Save Electricity Essay for Students and Children

500+ words essay on save electricity.

Electricity is an essential resource for a thriving life. It runs our daily life. Life without electricity would be impossible to imagine now. We generate electricity using coal or natural gas. However, people do not realize the natural resources to do as are limited and non-renewable. We must conserve electricity so that we can conserve these resources.

In other words, electricity serves mankind greatly. We must stop the wastage of power. The world will lose its light if there is no electricity. Moreover, careless behavior by humans must be checked. We need to realize the importance of electricity to save ourselves from the darkness.

Need for Electricity

Electricity is needed in almost every sphere of life now. We need it to lead a comfortable life full of all amenities and services. The world will become dormant without electricity. For instance, all our health and education facilities are conditioned by electricity. If there is no electricity, the surgeon won’t be able to perform his surgery. Moreover, students won’t be able to gain practical knowledge.

Likewise, motor mechanics in the garages and engineers in the factory depend on electricity. Furthermore, the passengers at the railway station and the airport can travel safely due to electricity only.

In addition, various means of transportation depend on electricity only. Trams and metros carry thousands of people every day. All this is made possible due to electricity only. Electricity boosts our modern life and helps in making it civilized.

How to Save Electricity

Firstly, all of us must understand that even a small step will go a very long way in saving electricity. For instance, if every person at each home switches on the fan when not in use, thousands of watts of electricity can be saved.

Similarly, if we use our air conditioners, heaters, ovens, refrigerators and more properly, we can successfully save large amounts of electricity.

Furthermore, try making use of natural light more. Do not keep the lights unnecessarily in the morning and afternoons. Make do with the natural light as it is enough. We must replace all our old appliances as they consume a lot of electricity. In other words, we must strive to make our homes energy efficient.

Moreover, always remember to unplug your electrical gadgets when not in use. These devices consume at least 10% of electricity even when inactive. Thus, unplug them to save electricity.

In addition, try to cut down your TV watching time. Encourage kids to read and play outside instead. Likewise, try using laptops in place of desktops. Desktops consume more energy than a laptop. You must also switch off the fans if you using your air conditioner, thereby avoiding unnecessary wastage.

Most importantly, installing solar panels can help you excessively. They are very economical and help in saving a lot of energy. The solar panels will help in consuming lesser energy that too economically. Similarly, the industries which use megawatts of electricity must install windmills. This can help in getting cheap electricity through natural means.

Energy Efficiency: The Clean Facts

Here’s what you need to know about energy efficiency and how you can help save the environment—and money—at the same time.

What Is Energy Efficiency?

Why is it important to use less energy, energy-saving tips, energy efficiency: for today and tomorrow.

Is contributing to the fight against climate change actually as easy as changing a light bulb? Granted, stemming the tide of global warming and rising sea levels is obviously more complicated than swapping in energy-saving LED bulbs. But energy efficiency is indeed an important—and often underappreciated—tool to reduce pollution and waste. After all, energy efficiency is America's largest energy resource, having done more to meet the nation’s energy needs than oil, gas, and nuclear power over the past four decades.

Energy efficiency harnesses technology to help avoid or reduce energy waste so that you can still turn on the lights, drive, or wash your clothes but use less energy doing so. (Similarly, energy conservation is also about smarter energy use but it relies on people cutting back on activities that consume energy, like turning off lights, driving less, or using appliances less often.)

Using less energy is good for your wallet (more on that in the energy-saving tips below) and the broader economy. Thanks to efficiency measures, U.S. energy use is about the same now as it was more than 20 years ago , even as the economy has steadily grown. Greater efficiency can also relieve stress on the power grid and infrastructure.

By reducing the amount of energy required for certain tasks, energy efficiency is also good for the planet. It can help to reduce air and water pollution from coal- and gas-fired power plants and avoid negative impacts on critical ecosystems . 

It cuts carbon pollution

Boosting energy efficiency in buildings, vehicles, appliances, and equipment is an inexpensive, low-impact way to reduce climate pollution, including carbon dioxide (CO2) emissions, on a grand scale. In fact, we need widespread adaptation of energy efficiency to reduce emissions at the pace and scale required to reach net-zero and combat climate change.

Since its founding in 1992, the U.S. Environmental Protection Agency’s (EPA’s) Energy Star label has been the gold standard for identifying the more energy-efficient appliances, buildings, and equipment. The EPA estimates that the program has reduced carbon pollution by 4 billion metric tons while saving $500 billion on household energy bills.

It creates jobs

As of 2022, more than 2.1 million Americans have jobs in energy efficiency. With greater investments, like those in the Inflation Reduction Act , we’re already seeing new jobs in research, production, installation, and sales. And as part of the same groundbreaking climate law, the U.S. Department of Energy (DOE) has announced $150 million in funding for states to train and support residential energy efficiency contractors. 

It lowers electric bills

The average U.S. household spends around $2,000 a year to power electronics, heat and cool spaces, warm up water, and keep the lights on. Energy-efficient appliances can save families hundreds of dollars a year on utility bills. In many cases, these long-term savings can make up for any price difference between efficient and inefficient appliances.

The cost savings from energy efficiency are especially powerful for low-income rural and urban households, as well as renters, who typically face a higher energy burden —the proportion of income spent on energy—than that of higher-earning households (partially due to lack of weatherization).

It improves lives

Energy efficiency can also help people live healthier, longer lives. One report found that cutting nationwide energy consumption by 15 percent for one year via efficiency measures could help save six American lives a day and avoid up to $20 billion in health-related problems. When power plants burn coal, oil, and natural gas, they release tiny particles into the air that we breathe in; these particles are linked to asthma, heart attacks, and lung cancer. Inside a home, inefficient ventilation and weatherization can also contribute to respiratory illnesses. Energy efficiency can even improve the comfort of everyday life , which may not be factored into most benefit statistics.

It strengthens independence

On a larger scale, energy efficiency improves energy security by not only making our power grid more resilient but also making the country less dependent on foreign sources of fossil fuels and the critical minerals in batteries .

Ready to join the energy efficiency revolution? Be sure to check our consumer guide for how to take advantage of the latest tax credits and rebates for making changes big and small, as detailed below.

Get smart about energy use

Start small by turning off electronics when they’re not in use, tweaking your TV settings, adjusting temperature settings, and setting timers. Hunt down “ energy vampires ” that consume electricity even when idle.

Buy efficient home appliances with the Energy Star label

Replacing older appliances with energy-efficient models can save the average household $450 a year . The Energy Star label , a voluntary program managed by the EPA and thousands of partners, can be found on 75-plus types of products, including major appliances, lighting, and home electronics.

For instance, a newer fridge with the Energy Star label uses 35 percent less electricity than a fridge reaching the end of its life span today (about 15 years). Energy Star washing machines use one-fourth less energy and one-third less water than standard models—cutting yet another utility cost. 

Consumers are getting a double bonus, because energy-efficient appliances like refrigerators, ovens, and dishwashers are also becoming more affordable. The Energy Star website can even direct you to rebates available in your area.

Heat and cool efficiently

U.S. households spend around $900 every year , on average, just to keep their homes at a comfortable temperature. But taking steps like investing in Energy Star–labeled heat pumps, air conditioners (ACs), and central air-conditioning units can cut those energy bills by $160 or more. 

Super-efficient electric heat pumps are a cleaner and more affordable option for both heating and cooling homes­ and businesses, particularly where oil and propane furnaces are the norm. Heat pumps keep things cool when it’s hot outside by removing unwanted heat from your home and directing it outdoors. When you want to keep your home warm, the very same appliance can be kicked into reverse. 

They also come in different forms, depending on your home’s setup: A central heat pump, for example, takes the place of a central AC, sitting in the same spot and using the same air ducts and thermostats.

As climate change fuels more extreme weather conditions, more and more people are making the move to purchase their first air conditioner. This is actually the best time for you to instead buy a heat pump that can replace both your standard AC and furnace and help reduce your utility bill.

The Energy-Efficient Home Makeover

What Are “EnergyGuide” and “Energy Star” Anyway?

With homes and offices accounting for 13 percent of the nation’s annual greenhouse gas emissions , you will also be doing your part to help curb the impacts of climate change by reducing the use of fossil fuels. Other benefits include cleaner air inside your home and helping to lessen the pressure on your areas’s electrical grid, especially during heat waves. So while the up-front cost of a heat pump might be slightly more than a standard AC without a heating function, the long-term benefits make it a worthwhile investment for your wallet and the environment.

In addition to swapping out major appliances, many homes are also installing smart thermostats for greater control— and savings . Even today’s Energy Star–labeled ceiling fans with light fixtures are dramatically more efficient than conventional units. (Ceiling fans can make a room feel cooler while using just a fraction of the energy of a central air conditioner.)

Finally, keeping cool in summer and warm in winter requires far less energy when your house is well sealed against the elements. Consider consulting with a weatherization professional to find drafts, connecting with your local utility or government for an energy audit, or going DIY . Then add insulation where you need it.

Warm up water more effectively

While they’re often not top of mind (rather, far below, usually in a basement or crawl space), water heaters of all types tend to account for more of a home’s energy consumption than cooking and refrigeration combined . But heat pump technology—the same technology that can heat and cool your home—is also the most efficient way to get that shower hot. Heat pump water heaters are more effective than electric resistance heaters and far cleaner than gas and propane water heaters, as they emit zero greenhouse gas emissions or toxins like nitrogen oxides while in operation.

Switch to LED bulbs

Today, half of U.S. homes are brightened with efficient LED light bulbs . And with the latest federal rules for lights, the DOE expects nationwide consumers to save nearly $3 billion per year on their utility bills while cutting carbon emissions generated by electricity production.

To help consumers, NRDC has long worked to create and champion state and federal energy efficiency standards for buildings and appliances, collaborate with cities to cut energy waste in larger buildings, encourage utilities to promote efficiency, and push for efficiency improvements in building codes . For your part, by finding ways to reduce your personal use of fossil fuels , you, too, can play a role in creating an energy-efficient future that improves the health of people and the planet.

Things you can do to use less energy and cut your bills

Saving Energy

• English English

Today's energy shortages and high prices makes it more important than ever to use energy wisely

With today’s global energy crisis resulting in high prices and shortages that are hurting consumers, businesses and entire economies, it has never been more important to use energy more wisely. We can do this through simple changes in behaviour and habits to consume less energy in our daily activities. We can also save energy by investing in more energy efficient products that reduce both our energy bills and our environmental footprint.  

Energy Saving Tips

7 ways you can save energy.

Learn more on how to save energy

1. heating: turn it down.

Lower your thermostat by just 1°C to save around 7% of your heating energy and cut an average bill by EUR 50-70 a year. Always set your thermostat as low as feels comfortable, and wear warm clothes indoors. Use a programmable thermostat to set the temperature to 15°C while you sleep and 10°C when the house is unoccupied. This cuts up to 10% a year off heating bills. Try to only heat the room you’re in or the rooms you use regularly.

The same idea applies in hot weather. Turn off air-conditioning when you’re out. Set the overall temperature 1 °C warmer to cut bills by up to 10%. And only cool the room you’re in.

2. Boiler: adjust the settings

Default boiler settings are often higher than you need. Lower the hot water temperature to save 8% of your heating energy and cut EUR 100 off an average bill.  You may have to have the plumber come once if you have a complex modern combi boiler and can’t figure out the manual. Make sure you follow local recommendations or consult your boiler manual. Swap a bath for a shower to spend less energy heating water. And if you already use a shower, take a shorter one. Hot water tanks and pipes should be insulated to stop heat escaping. Clean wood- and pellet-burning heaters regularly with a wire brush to keep them working efficiently.

3. Warm air: seal it in

Close windows and doors, insulate pipes and draught-proof around windows, chimneys and other gaps to keep the warm air inside. Unless your home is very new, you will lose heat through draughty doors and windows, gaps in the floor, or up the chimney. Draught-proof these gaps with sealant or weather stripping to save up to EUR 100 a year. Install tight-fitting curtains or shades on windows to retain even more heat. Close fireplace and chimney openings (unless a fire is burning) to stop warm air escaping straight up the chimney. And if you never use your fireplace, seal the chimney to stop heat escaping.

4. Lightbulbs: swap them out

Replace old lightbulbs with new LED ones, and only keep on the lights you need. LED bulbs are more efficient than incandescent and halogen lights, they burn out less frequently, and save around EUR 10 a year per bulb. Check the energy label when buying bulbs, and aim for A (the most efficient) rather than G (the least efficient). The simplest and easiest way to save energy is to turn lights off when you leave a room.

5. Grab a bike

Walking or cycling are great alternatives to driving for short journeys, and they help save money, cut emissions and reduce congestion. If you can, leave your car at home for shorter journeys; especially if it’s a larger car. Share your ride with neighbours, friends and colleagues to save energy and money. You’ll also see big savings and health benefits if you travel by bike. Many governments also offer incentives for electric bikes.

6. Use public transport

For longer distances where walking or cycling is impractical, public transport still reduces energy use, congestion and air pollution. i f you’re going on a longer trip, consider leaving your car at home and taking the train. Buy a season ticket to save money over time. Your workplace or local government might also offer incentives for travel passes. Plan your trip in advance to save on tickets and find the best route.

7. Drive smarter

Optimise your driving style to reduce fuel consumption: drive smoothly and at lower speeds on motorways, close windows at high speeds and make sure your tires are properly inflated. Try to take routes that avoid heavy traffic and turn off the engine when you’re not moving. Drive 10 km/h slower on motorways to cut your fuel bill by around EUR 60 per year. Driving steadily between 50-90 km/h can also save fuel. When driving faster than 80 km/h, it’s more efficient to use A/C, rather than opening your windows. And service your engine regularly to maintain energy efficiency.

Hang your clothes instead of using a tumble dry

A standard clothes dryer consumes as much energy per year as an energy-efficient refrigerator, clothes washer, and dishwasher combined. Line drying saves money and promotes energy conservation. It also enhances freshness removing strong odors and it is gentle on clothing. One small step in making a difference!

Top 10 Reasons To Line Dry Laundry

Use your laptop more than your desktop

Laptops use an average of 20 to 50 watts of electricity to run, whereas desktop computers use an average of 60 to 200 watts of electricity to run. The reason for this is that laptops run off of battery power and desktops are continuously plugged into a power source that drains energy.

Make sure to unplug your laptop and docking station from the power source once it's fully charged. Not only does this help reduce your energy usage, but it also optimizes your laptop's battery life to last longer.

Learn more about the Laptop vs. Desktop Debate

Switch off your power strip before you leave

You can save energy and money when you remember to turn off your power strips when not in use!

Phantom load or Vampire Power is the electricity drawn from outlets when equipment is off or on sleep mode but still plugged in. Many types of electronics and office equipment, including computers, printers, and phone chargers continue to draw electricity even when they are on sleep mode.

Phantom load can account for up to 15% of the electricity used by equipment and appliances!

Always unplug electronics and appliances when not in use. You can make this task easier by using outlet/power strips, which can turn everything off with the flip of a switch. To help you remember, put the power strip in easy-to-reach locations.

Switch to LED bulbs Light Emitting Diode (LED) lights last longer than incandescent or halogen bulbs. They are energy efficient, very durable, and save you money. Replace your inefficient lights with LEDs, because it’s also 2020. Don’t forget to dispose of the old lights properly! Learn more about disposing of light bulbs responsibly

Consider switching to a renewable energy provider and using energy-efficient appliances

Look for providers that use renewable energy sources and sustainable, ethical practices. Switching to energy-efficient appliances and equipment in just the top 6 product sectors has the potential to reduce global electricity use by 10%.

Learn more about the UN Environment Programme's Global Alliance for Energy-Efficient Appliances and Equipment.

Charge your phone in airplane mode and before bedtime

While charging, switch your phone to airplane mode, so that the phone does not slow down the charging process by continually burning energy trying to connect with cell phone towers and plot your location with its GPS function. When you switch to airplane mode your phone charges more quickly.

The brighter the screen setting, the more power it uses and vibration uses more energy than a ringtone. Low Power Mode also saves battery life, therefore less energy consumption. And remember -unplug your charger if not in use! Tips For Saving Energy With Your Mobile Phone .

Unplug mobile phone and laptop chargers

Always unplug electronics and appliances when not in use. Unplugging will save you energy, money, and can prevent electrical fires. When the power strip is left on, the devices plugged into it continue to use energy and actually increase your energy usage.

The Northern Resources Defense Council found that devices in sleep or standby mode account for about one-quarter of all residential energy consumption.  Learn more about where chargers pull their power from.

Delete unwanted files from cloud storage

Reduce your carbon footprint by organizing your files and eliminating unnecessary data from cloud storage! Companies offering cloud data storage need warehouses filled with servers running nonstop. These data centers consume massive amounts of energy since they require AC systems to avoid overheating. Learn more about the environmental threat posed by data centers.

Delete old emails

78% of all incoming emails are spam, requiring 33 billion kilowatt-hours of electricity and causing 20 million tonnes of CO2e per year. If every single person in France deleted 50 emails, the energy savings would be equivalent to turning off the Eiffel Tower's lights for 42 years. By cleaning out your inbox , you can save electricity and reduce carbon emissions without even leaving your desk! 

Let's go green and save water, paper and energy, let's use less plastic and improve air quality. It's possible.

Saving energy around the house is good for your wallet, good for you and the family, and good for the environment. But energy conservation around the house is more complex than just using less electricity, because anything you do at home that requires water or fossil fuels is also energy intensive. There's also the point of caring for our planet and it's environment—but if everyone does their part and saves energy, then that problem would be significantly reduced. Cutting energy use around the house involves reducing electricity and water use, being smart about when and how you use energy, preventing energy loss, and choosing appliances and fixtures that will help you save energy.

Making Your Home More Energy Efficient

• Lighting typically accounts for roughly 10 percent of your energy use. A single CFL bulb could save you about $30 in energy costs over the course of its life compared to an incandescent bulb. They cost much more but they last much longer, [1] X Research source

• Don’t set your water heater temperature below 120 F (49 C). This can allow dangerous pathogens to live in your water tank.
• Cover the tank with an insulating blanket.

• Install weather stripping on doors, windows, and attic or crawl space access holes.
• Seal up mail slots that don’t get used.
• Seal openings and cracks in the roof, walls, around electrical outlets, and around pipes and wires with expanding caulk or foam.
• Plug large holes, such as by using a foam product.
• Install transparent plastic sheeting on drafty windows.
• Buy thermal curtains. These touch the floor and are wrap around to touch the walls, to trap cold air behind them. Normal curtains allow the cold air to escape by convection airflow.

• Buy washers and dryers with many energy-saving features.
• Front-loading washing machines are the most energy-efficient.
• Refrigerators with the freezer on top or the bottom are more energy-efficient than side-by-side refrigerator-freezers [9] X Research source
• Stoves with ceramic induction cooktops are more energy-efficient than traditional range cooktops
• Tankless on-demand water heaters are much more energy-efficient than tank-style water heaters

• If you have storm windows, caulk around their frames. Wind draws air out through storm windows and primary windows if the storm windows are not air-tight.
• In many places, there are tax credits available for homeowners who upgrade to energy-efficient windows, so look into government programs where you live.

Practicing Energy-Conscious Habits

• Use a toaster to make toast
• Use a toaster oven to cook, roast or bake small portions
• Use a steamer or rice cooker to steam rice and vegetables
• Use a frying pan to sauté or stir fry instead of baking or roasting
• Use a microwave to bake, steam, and boil all sorts of foods

• When you go away for overnight or longer, unplug all appliances and electronics, because many of them use energy even when they're not on. To make your job easier, use power strips for appliances that are often used together, such as the TV, stereo, and DVD player. [14] X Research source
• Unplug phone chargers and other devices when you're not using them too, because they draw power as long as they're plugged in. [15] X Research source
• Cut down on the Phantom Loads. Some appliances and electronic devices continue to consume energy even when they are not in use. This is commonly referred to as the Phantom Load. It is usually caused when electronics are still plugged in or are not turned off. You can ensure that you stop wasting energy and your money by unplugging your electronics or by turning off the power strip where the devices are plugged in.

• Also, leave the shades and curtains in the bedrooms completely open while you are gone. The bedrooms will be heated by UV radiation, like greenhouses. .

• Taking shorter showers
• Turning off taps when you're lathering up
• Filling the sink with water to wash dishes rather than letting it run
• Saving kitchen water for the garden
• Reusing cooking water
• Flushing less
• Investing in water-smart fixtures and faucets
• Capturing condensation from your air conditioning unit and using it to water plants.

• To save even more water with the washing machine, always choose the appropriate load size so the machine will adjust the water level.
• With the dishwasher, you can also save energy by turning off the drying cycle, and letting dishes drip and air dry instead. [16] X Research source

• Reserve hot water cycles for extremely soiled loads of laundry, but set the rinse cycle so it uses cold water.

• Avoid drying clothes inside, as this can create moisture and mold in the house.

• In winter, the leaves will fall off the trees and allow warming sunlight into your home.
• Instead of planting deciduous trees, you can also install thick curtains that will block the sun, sun screens, or a UV-protective film on the windows to tint them. [20] X Research source

• Rechargeable batteries are also cheaper in the long run, because you don’t have to keep buying them. [21] X Trustworthy Source U.S. Department of Energy Official site for the U.S. Department of Energy, which provides resources related to energy safety, conservation, and efficiency Go to source
• Rechargeable batteries are also better for the environment, because they don’t go to the landfill after each use.

• Depending on your municipality, items you may be able to recycle include glass, aluminum cans, bottles, plastic, cardboard, paper, and more.
• Buying products with minimal packaging is also a good way to save energy, because no resources or energy is wasted manufacturing or recycling the packaging. [22] X Research source

Reducing Heating and Cooling Needs

• Some furnace filters aren't washable, and they’ll have to be replaced every three months or so.

• Set the thermostat so that the furnace or air conditioner comes on less during the day when nobody is home, and at night when everybody is sleeping.
• Use the thermostat to turn down the heat or air conditioning when you're away on vacation, but set it to come back on just before you arrive home. There are also some thermostats that you can operate remotely, such as by using a computer or smartphone.

• Sealing these leaks could save you up to 20 percent on your energy bills. [25] X Trustworthy Source U.S. Department of Energy Official site for the U.S. Department of Energy, which provides resources related to energy safety, conservation, and efficiency Go to source

• In winter, use sweaters, thick socks, slippers, and blankets to keep warm at home.

• A small space heater may even be sufficient in winter if you live in the southern part of the US.

Recycling is the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products. Recycling often saves energy and natural resources.

Natural resources include land, plants, minerals, and water. When we use materials more than once, we conserve natural resources.

Recycling saves energy and other resources

Making a product from recycled materials almost always requires less energy than is required to make the product from new materials. For example, using recycled aluminum cans to make new aluminum cans uses 95% less energy than using bauxite ore, the raw material aluminum is made from.

Electricity Costs Are Surging. Here's How You Can Save

Higher electricity costs this summer can be blamed on sweltering temperatures and rising demand. Here's what you can do to save.

• Newsletter sign up Newsletter

Unfortunately, you can expect to pay more for your utility bills this summer. From April 2021 to April 2024, electric prices have increased by 24%, and you’ve no doubt been feeling the strain on your wallet as the weather warms up and the number on your thermostat goes down. Here's a look at what's causing this rise in energy prices and what you can do to save money. 

Why are energy prices rising?

Increased costs are due to a number of factors, including increased demand, especially among energy-intensive data centers. Electricity consumption is now expected to grow 4.7% in the next five years, up from the 2022 forecast of 2.6%. “Data centers whose chips run artificial intelligence are especially energy-intensive, and more are coming,” Jim Patterson writes in the Kiplinger Letter . “Data centers in general account for 4.6% of demand. By 2026, that figure stands to rise to 6%.” 

He also shares that increased construction of high-tech manufacturing facilities, appliances switching from natural gas to electricity and more electric vehicles are also driving up electricity consumption. But along with this increased demand comes supply constraints. And this all results in higher rates on electricity bills.

“How much higher depends on a lot of factors, such as your region, the price of natural gas (the leading fuel source for generation) and how quickly government officials try to ramp up renewable power,” Patterson writes.

2024 to be one of the hottest summers ever

Not to mention the anticipated heat waves this summer that will surely cause you to crank up your air conditioning, and in turn, your power bill. The more energy you use to combat those roasting temperatures, the more money you’ll inevitably spend.  

From June through August, temperatures are expected to reach 2 degrees above historical averages across more than half of the country, Accuweather notes. Experts believe that there’s a good chance this summer could be one of the hottest on record in the U.S., especially from the Rockies to the East Coast.

“We expect electricity consumption will grow in all major consuming sectors this year, but especially in the residential sector, which we expect will increase by 4%” reports the U.S. Energy Information Administration in the March edition of its Short Term Energy Outlook . “Much of the forecast year-over-year growth in residential electricity occurs during the summer months of 2024.”

How to cut your electric bill summer 2024

And while you can't directly control how much your electricity costs, you can control how much you use. One of the best ways to save on energy bills , and also one of the easiest, is to keep your thermostat at the right temperature. According to the U.S. Department of Energy (DOE) , the smaller the difference between indoor and outdoor temperatures, the lower your overall cooling bill will be. 

They recommend keeping your thermostat set to 78 degrees in the summer months while you're at home, and even higher while you're away. You can easily control the temperature in your home by opting for a smart thermostat . "Programmable thermostats will avoid any discomfort by returning temperatures to normal before you wake or return home," states the DOE. 

This means you'll need to find other ways to stay cool this summer. Check out our 12 tips to stay cool without air conditioning , which include maximizing shade in your home, prioritizing good insulation and properly using fans to beat the heat. Did you know your fan should rotate in a different direction depending on the season? Particularly, counterclockwise in the summer months? By reading the article, you'll find more information on how to save money — and not sweat to death in those record-setting temperatures.

Metaheuristic methods have emerged as powerful tools for solving complex optimization problems in various domains, including the sustainability of water distribution systems. They provide efficient and effective solutions by mimicking natural processes and searching for the optimal option within a large solution space. Despite the existence of these methods in the water distribution field for several years, a direct comparison between the various proposed solutions often proves challenging, due to the different parameter definitions used by the authors. The present review presents the solutions proposed by a total of 36 research papers taken from the Web of Science, Scopus and Google Scholar databases focusing on the application of metaheuristic methods for leakage reduction and energy saving in water distribution networks. The review is intended to facilitate comparative analysis among the solutions proposed by authors concerning key aspects of the optimization process. These aspects include the definition of the algorithm, the specification of the objective function, and the strategies employed for reducing the search space. The characteristics of the networks used as case studies by the reviewed papers are also presented to allow the reader to evaluate the applicability of the solutions to specific networks.

Avoid common mistakes on your manuscript.

1 Introduction

Aging pipelines together with other stresses have rendered the water distribution networks (WDNs) vulnerable to leakage, creating one of the most significant challenges facing WDNs all over the world in recent decades. The effects of leakages could be mitigated in network management operations by adopting technological solutions to monitor and control more efficiently the WDN. For instance, installing pressure-reducing valves (PRVs) reduces excessive pressure in the network and consequently the amount of leakage. This approach for leakage reduction is widely used by water utility management because it has proved to be effective, inexpensive, and immediate.

Despite the theoretical simplicity of the solution, one of the main issues regarding its implementation is the need to identify an optimal location for PRV installation and its ideal setting, which is the pressure that the PRV must regulate downstream of the valve. Some researchers suggest the installation of devices for energy recovery in place of a simple PRV; this would combine the solution to leakage reduction with energy recovery, improving two aspects of water distribution sustainability: energy and water saving.

The problem of valve location is a non-linear non-convex problem. Assuming a network of 150 pipes, the placement of five PRVs entails the evaluation of over 591,600,030 possible combinations of positions without considering the evaluation of the best valve setting, which would add further combinations. This kind of large search space highlights the importance of a proper optimization methodology, such as the application of metaheuristic methods. The qualities of metaheuristic methods include the ability to explore efficiently large search spaces, find good solutions without strict assumptions, and adapt to different problems, making them valuable tools for solving real-world optimization problems in various fields. The interest of researchers in metaheuristic methods for leakage reduction and energy saving in water distribution networks (WDNs) spans several decades and has led to the development of several possible approaches.

Genetic Algorithms (GA), inspired by natural evolution, were among the first metaheuristic methods applied to WDNs (Cembrowicz and Krauter 1977 ). GA were mainly used to optimize pipe layouts and pressure management, aiming to mitigate leakage and energy consumption.

Over time, other metaheuristic methods based on different approaches have emerged (Samadi-Koucheksaraee et al. 2022 ). Simulated Annealing (SA), which simulates the annealing process in metallurgy to find near-optimal solutions, was firstly introduced by Sousa et al. ( 1970 ). Particle Swarm Optimization (PSO), inspired by the collective behaviour of bees in a swarm (Wegley et al. 2000 ), was first introduced to optimize pump scheduling and minimize leakages. Recently, Ant Colony Optimization (ACO) has gained attention for its ability to solve complex optimization problems (Maier Holger et al. 2003 ). ACO mimics the foraging behaviour of ants, allowing for the optimization of pipe layouts, valve location, and leakage detection in water distribution networks.

Only recently, thanks to the advent of new technologies, researchers have suggested to combine water leakage reduction solutions and energy recovery. Some authors, also considered in this review, suggested replacing simple PRVs with small turbines ( Ferrarese and Malavasi 2020 ; Giudicianni et al. 2023 ), inverse pumps, cross flow turbines, and other alternative technologies able to recover energy and control the flow. It is evident that the deployment of sophisticated network management methodologies demands to rapidly develop hydraulic devices that meet new standards and requirements, such as remote control or increased frequency of variable monitoring (Ferrarese et al. 2022 ). Nowadays, the integration of machine learning is also gaining momentum, aiming at improving the capacity of predicting consumer behaviours so as to manage the network pressure accordingly (Shirvani-Hosseini et al. 2022 ).

This review aims to be a reference document for researchers and practitioners of the various metaheuristic methodologies mentioned above, which were developed by researchers to regulate the pressure in the network, limit leakage, and recover energy. Furthermore, the case studies used in various studies to validate optimization methodologies are analysed. Specifically, all the key features of the networks used as case studies are reported, allowing the reader to assess their applicability to the different specific cases.

Section  2 describes the reason for the review and methodology used for it. Section  3 presents the state of the art, highlighting the differences and similarities between the various approaches introduced by the works under review. Finally, Section  4 proposes conclusions and perspectives for future developments.

2 Reason and Motivation of the Review

Metaheuristic methods have been introduced in the field of water distribution network optimization for several years with the main but not sole purpose of improving network sustainability by reducing losses and recovering energy. Methods based on different algorithms, diverse objective functions, and various strategies for reducing the search space have been proposed. The proposed solutions are sometimes challenging to compare, also due to the different definitions used by the authors. This review systematically organizes the contributions of various authors, categorising them based on key aspects of the optimization process: algorithm design, objective function formulation, search space reduction, and the case studies used by authors to validate their methods. This structured approach facilitates reader comprehension, allows for a more effective comparison of proposed methodologies and helps selecting the most suitable approach for addressing specific problems of interest.

This review covers the papers published over the last three decades, from 1990 to May 2023, concerning the use of metaheuristic methods for valves location and settings in WDNs with objective leakage reduction and/or energy recovery. The keywords used to search for publications are: metaheuristic methods, genetic algorithms, water distribution network optimization, pressure management, leakage reduction. The databases queried are Web of Science, Scopus and Google Scholar.

The main section of the paper, “Current situation”, is organized in four sub-sections:

Algorithms: presentation of the main optimization approaches introduced in the reviewed papers.

Reduction of the search space: detailing techniques for search space reduction.

Objective functions: comparison of the various objectives and penalty functions and their corresponding equations.

Case studies: illustration of both real and theoretical networks used to validate and evaluate the performance of the different methodologies.

3 Current Situation

3.1 algorithms.

Typically, algorithms used for optimization in distribution networks fall into two fundamental categories: deterministic and stochastic. Each approach has its own set of advantages and disadvantages. The deterministic approach ensures that the solution found is the absolute optimum. This characteristic represents a fundamental difference with respect to stochastic methods, which instead are characterized by uncertainty in finding the absolute optimum in the search space.

The deterministic approach is suitable for problems characterized by continuous variables, linear objective functions and constraints. It can also be applied to nonlinear objectives and discrete variables such as the problem of locating valves in WDNs, but only in a restricted number of instances. For example, Jowitt and Xu ( 1990 ) used iterated linear programming to find optimal valve control, whereas Vairavamoorthyl and Lumbers ( 1998 ) used the sequential quadratic programming method. The authors were constrained to use a linearized model of the network to be able to evaluate the fitness function. Pezzinga and Gueli ( 1999 ) proposed a fully deterministic methodology based on sequential addition also used in comparison or coupled with other methodologies, as proposed in Creaco and Pezzinga ( 2018 ).

The main recognized issues with deterministic methodologies (Liberti and Kucherenko 2005 ) are their difficulty in dealing with problems where the simulation is required to evaluate objective function and constraints. They are also computationally expensive and slow convergent methods. For these reasons, the stochastic approaches have gained importance to solve valve location and pressure management issues.

The stochastic approach implies the use of randomness in finding the optimum solution and it consists of two classes of algorithms: specific heuristics and metaheuristics (Talbi 2009 ). The latter are problem-independent, much faster, and less expensive (Liberti and Kucherenko 2005 ). The metaheuristic approach suits well Non-deterministic Polynomial, Non-linear Non-convex combinatorial problems, to which many water resources field-related problems belong. Many metaheuristics methods have been applied to optimize numerous issues concerning not only the design of the water distribution network (WDN) (Sangroula et al. 2022 ) but also the rehabilitation planning (Elshaboury and Marzouk 2022 ), operation (Behandish and Wu 2014 ), water quality control and WDN security (Yudina et al. 2021 ).

In the following, the stochastic methodologies used in the reviewed papers for PRV or energy recovery device’s location and setting are presented together with the methodologies used to reduce the search space and drive the evolution of the algorithms. Finally, hybrid methodologies (between deterministic and stochastic) are also presented.

3.1.1 Genetic Algorithms

One of the most prominent and established metaheuristic algorithm used for water distribution networks optimization is the genetic algorithm (GA). Araujo et al. ( 2006 ) used GA in a two-phase methodology, to find the optimal location in the first phase and the optimal setting of the PRV in the second phase. The simulation strategy is to assume a pseudo-valve on each pipe, considering an increased roughness 90% greater than the normal roughness as a potential location for a valve. They used the elitism technique and total replacement of parents by children. The total number of valves is a constraint of the problem. Making several repetitions, they found that installing 4 PRVs reduced leakage by 19% in the considered test case (see Table  3 ). The main drawback is that considering a pseudo-valve for each pipe, the computation cost for the real network rises considerably. Besides that, the method has some ambiguity about dealing with pressure violations, i.e., pressures under the limit for a sufficient service to water users.

Using real coded GA, Ali ( 2015 ) implemented tailored genetic operators of crossover and mutation (Gaussian mutation and an improved arithmetical crossover) appropriate for mixed integer variables, optimizing the location and average setting synchronously in one phase. It reduced leakage by 16% in the benchmark network considered (see Table  3 ). However, the application of this methodology requires the skeletonization of the network to only consider the most important pipes. In addition, when there are huge variations in demand, it entails a forecasting model, especially for real-time applications.

Using binary grey representation, exponential rank selection, uniform crossover, bitwise mutation and partial elitism, Covelli et al. ( 2016a , b ) went a step further, also considering the direction of valve installation as a decision variable, and aiming to minimize the whole cost associated with installation and purchase of valves as well as the cost of water losses.

3.1.2 Other Metaheuristic Algorithms

Other studies opted for different metaheuristic algorithms, such as Scatter Search used by Liberatore and Sechi ( 2009 ) with a modest computation burden according to the authors, or De Paola et al. ( 2017a ) who used Harmony Search (HS) with double harmonic components to optimize the valve location and setting in a single step. The obtained leakage reduction rate is almost similar to the one obtained by Araujo in a 24 h simulation on the same reference network (see Table  3 ), but the method showed less sensitivity to the selected parameters. Moreover, the small computational time required by the calculations suggests the suitability of HS for real-time optimization of the WDN.

Jafari-Asl et al. ( 2020 ) applied the PSO algorithm to minimize leakage through a two-step process for optimal location and then for a 24 h setting testing of three characteristic demand conditions. The method achieves a reduction of the losses by 19.5% maintaining the minimum pressure in the reference nodes.

Mehdi and Asghar ( 2019 ) used PSO to minimize leakage and maximize reliability via the network pressure reliability index (NPRI). The method reduced leakage by 19% considering the fuzzy logic for evaluating pressure in the WDN.

3.1.3 Multi-Objective Algorithms

When the problem to be solved requires to set more than one objective, and in order to give the decision maker various possibilities to choose among, a Pareto front needs to be generated, where the best solutions are represented on the closest curve to the origin. In recent years, many researchers (Gupta et al. 2017 ; Latifi et al. 2018 ; García et al. 2019 ) have adopted this method for reducing water leakages.

Nicolini and Zovatto ( 2009 ) applied the Non-Sorting Genetic Algorithm NSGAII to find a compromise between the minimization of the number of valves and the minimization of the total leakage in the system. This method uses a combination of non-dominated sorting and elitism to maintain a diverse and well-distributed population of solutions throughout the optimization process. NSGA-II introduces the concept of crowding distance to promote the spread of solutions along the Pareto front. The number of PRVs is used as a surrogate for installation costs. The method obtained a leakage reduction rate of 14.8% by installing three valves, while when installing five valves, it reached a leakage reduction rate of 16.5%. The study is applied to the reference network indicated in Table  3 .

Saldarriaga and Salcedo ( 2015 ) also used NSGAII to trade off the unperceived financial cost of water loss against the annual cost of valve installation and maintenance. The results show that the valves should be installed in leakage-free areas to decrease the pressure’s surface, thus reducing the leakages downstream the PRVs. However, the 15% reduction achieved is lower than the best solution (31%) found by (Giugni et al. 2014 ) on benchmark networks (see Table  3 ).

Nicolini et al. ( 2011 ) compared NSGAII and Epsilon Multi-Objective Evolutionary Algorithm (Epsilon-MOEA) in terms of minimization of the number of valves versus minimization of total leakage. The Epsilon-MOEA method extends the traditional non-dominated sorting approach by introducing an epsilon dominance concept. The "epsilon" parameter controls the level of convergence desired. By manipulating this parameter, users can obtain a diverse set of solutions along the Pareto front, striking a balance between convergence and diversity. The authors found that Epsilon-MOEA behaves in a better way than NSGA-II and it appears to be more robust to the variation of the initial seed.

3.1.4 Hybrid Algorithms

Taking advantage of the exploration capability of metaheuristics and the fast convergence of deterministic approach, some researchers tried to create a hybrid between the two methods. Reis et al. ( 1997 ) embedded linear programming in the genetic algorithm to find the optimal valve settings for each location of valves proposed as a solution by the genetic algorithm.

Creaco and Pezzinga ( 2018 ) tried to compare NSGAII and the sequential adding (SA) method, embedding linear programming to assess the fitness function in both algorithms. They found that GA outperforms SA when the number of valves exceeds 4, due to the non-linear effects of WDNs. SA needed less computation, whereas GA can account for other issues in the evaluation of the fitness.

Creaco and Haidar ( 2019 ) combined three algorithms: NSGAII for location, a Fast-Greedy partitioning algorithm to divide the network in DMAs, and iterated linear programming to optimize the setting of PRVs. They searched for a trade-off between minimizing daily leakage volume, installation cost and demand uniformity.

3.2 Reduction of the Search Space

Reducing the search space is paramount as it effectively reduces the computational cost and, as a consequence, the time needed to apply a methodology. For example, a 40% reduction in potential locations for valves may reduce by 88% the possibility of having to install a network of 100 pipes and 4 valves, which will accelerate the process consistently and reduce the computational cost. To reduce the search space, different criteria have been implemented based on hydraulic considerations. These criteria allow one to exclude less important pipes placing a valve on which has a negligible effect on the pressure in the rest of the network.

This criterion could be Pipe Index PI (Ali 2015 ), specific power SP (Saldarriaga and Salcedo 2015 ), Valves Selection Index VSI (Mehdi and Asghar 2019 ) or Pipe Closure Index PCI (Dini and Asadi 2020 ). Saldarriaga and Salcedo ( 2015 ) and Salcedo and Saldarriaga ( 2018 ) compared SP, PI and a sectorization criterion that measures the hydraulic impact of closing a pipe. The authors deduced that both the SP and the sectorization criterion could reach best solutions but the latter entails higher computational complexity. All the search space reduction methods mentioned so far aim to create a list of the pipes ordered according to their importance. In the following, the different indexes are specified:

pipe index, PI, (Ali 2015 ) is defined as:

where \(Q\) is the pipe flow; \(L\) and \(D\) are the pipe length and diameter, respectively; and CHW is the roughness coefficient of the pipe. Arulraj and Rao ( 1995 ) found that pipes that have the greatest impact on the whole network have higher values of this index.

specific power, SP, (Saldarriaga and Salcedo 2015 ):

where: \({h}_{f}\) is the friction loss and \({h}_{m}\) is the minor loss

valves selection index, VSI, (Mehdi and Asghar 2019 ):

where \({Q}_{k}^{t}\) is the flow of pipe \(k\) from node i to node j at time t ; \(\Delta {P}_{ij}^{t}\) is the pressure head difference between node i and j at time t ; \({CHW}_{k}^{t}\) is the roughness coefficient of pipe \(k\) at time t; and T is the simulation period time.

pipe closure index, PCI, (Dini and Asadi 2020 ):

where \({D}_{io}^{t}\) is the optimal diameter of pipe i at time t , which is calculated in the calibration process; \({D}_{i}\) is the real diameter of each pipe; \({Q}_{i}^{t}\) is the flow rate of pipe i at time t ; \({q}_{j}^{t}\) is the nodal demand of node j at time t; N is the number of nodes; and T is the simulation period time.

3.2.1 Penalty Functions

Penalty functions play a vital role in metaheuristic methods for handling constraints. These functions help transform constrained problems into unconstrained problems, allowing the efficient exploration of the search space. When a solution violates a constraint, a penalty value is added to the objective function, penalizing the infeasible solutions. This encourages the algorithm to avoid violating constraints during the search process. Choosing an appropriate penalty function is crucial as it directly influences the algorithm's convergence and the quality of the final solutions. Balancing the trade-off between exploration and exploitation is essential to ensure algorithm effectively navigate constraint-rich search spaces. In pressure management problems, penalty functions are usually used to guarantee that the pressure in the demand node satisfies the consumer expectations, hence equal or above the pressure of service \({p}^{min}\) that usually ranges between 20 and 30 m of head. Considering a single time step and a node j, a penalty function used in several works can be generalized as follows:

where p j is the service pressure at node j ; \(a\) , \(b, c,\) and d are coefficients that change depending on the authors as follow (Table  1 ).

Recently, Sangroula et al. ( 2022 ) suggested the introduction of a specific penalty function based on the target velocity in the pipe to be used together with the penalty based on pressure. Moreover, the pressure considered in Eq.  5 is a target pressure rather than a minimum pressure like the one used by other authors, giving penalties both when the pressure at the node is below and when it is above the target with different weights. The suggested penalty function on a single time step and link is as follows:

where \({f}_{p}({V}_{i})\) is the velocity penalty at a given link i; \({V}_{i}\) is the flow velocity at link i; \({T}_{V}\) is the target velocity; \({V}_{P1}\) is the velocity penalty coefficient if the velocity at a given link is above target velocity (equals to 0.3); and \({V}_{P2}\) is the velocity penalty coefficient if the velocity at the link is below target velocity (equals to 0.06).

A penalty function that unifies penalties based on conditions on both the nodes and pipes can be written as follows:

where \({OF}_{pen}\) is the penalty function that can be introduced in a general objective function; \({f}_{p,j}\) is a generic penalty function for nodes; and \({f}_{p,i}\) is a generic penalty function for links.

3.3 Objective Functions

An objective function is a function that is minimized or maximized through the search process. In the following, the main objective functions introduced by the authors are reported. Table 2 below lists all equations reported in the following section with cross reference to their authors, also specifying the main objective of the papers, the optimization algorithm, the optimization methodology, and the constraints of the problem. The last column of the table indicates the equations used to define the objective function of the problem. All the equations reported have been adapted is such a way as to always use the same symbols for their parameters, to help the reader comparing the different approaches.

3.3.1 Leakage Reduction

The most adopted objective for valve placement problems is the minimization of leakage volume. Leakage volume can be modelled considering the following equations:

where \({W}_{L}\) is the total period leakage volume; \({W}_{L,\Delta t}\) is the cumulated leakage volume from all nodes N n at each time step (or load condition); \(\Delta t\) is the time step of the problem; \({N}_{\Delta t}\) is the number of time steps; \({\widetilde{Q}}_{j}\) is the leakage flow at node j ; \({p}_{j,\Delta t}^{\beta }\) is the service pressure at node j at time step \(\Delta t;\) \(K_{j}\) is a fixed leakage coefficient for the node j and β equals 1.18 in several papers. In Eq.  11 , \({c}_{i}\) is the discharge coefficient of the orifice, which depends on several characteristics such as shape, diameter, material, and age, whereas L ij is the pipe length between nodes i and j , and M is the number of pipes connected to the node j .

Considering a specific \({K}_{j}\) coefficient for each node, the Objective Function (OF) devoted to the minimization of the leakage volume (W L ) can be summarized as follows:

Coefficients \({K}_{j}\) and \(\beta\) are not always specifically defined by authors.

3.3.2 Costs Minimization

Many researchers based the search of the optimal solution on cost minimization. This is often used as a surrogate of minimization of the number of valves to be installed in the network.

The costs considered by most Authors are:

the cost of water not sold due to leakage \({C}_{tot,L}\) ; this amount can be calculated as:

where \({U}_{NP}\) represents the unperceived profit per lost unit of water.

the cost composed by the purchase, installation and maintenance cost of the valves \({C}_{tot,v}\) ; it can be defined as:

where C cv and k are the parameters of a potential regression that represents the increasing capital cost of valves according to their diameter, and d i stands for the diameter of the i-th valve.

The total amount of costs can be expressed as:

where a penalty function \({OF}_{pen}\) is added to consider penalties caused by problem constraints related to special features of the network.

To extend the cost analysis and also consider the sustainability of investment, Covelli et al. ( 2016a ) valuated the cost of the intervention during the lifetime of the installed valve ( \({N}_{EWT}\) ):

The total cost of the investment is then calculated as:

where N EWT is the Expected Working Time of the valves before their replacement (years); W lost is the expected volume of water lost over 1 year; \({c}_{{\text{CM}}}\) is the initial cost for a single unit of water lost; r WL is the rate at which the price of the volume of water that could be delivered to users if no longer dispersed in the subsurface would grow annually; ν and N valve are the generic PRV and the whole number of PRVs considered in the simulation, respectively ( ν  = 1,2, …., \({N}_{valve}\) );  \({C}_{maint,{\text{v}}}\) . are the costs sustained for the maintenance of both the PRV and manhole; \({C}_{Inst,{\text{v}}}\) are the costs sustained for purchasing the PRV, the construction of the related manhole, and the installation of the PRV in the manhole, evaluated at the end of the expected PRV working time.

3.3.3 Pressure Management

A widely shared objective in the literature is pressure management; the discrepancy between the actual pressure and the target or minimum pressure of service in each demand node is usually minimised to reduce leakage by considering the following objective function:

where \({N}_{\Delta t}\) is the number of simulation period time \(\Delta t\) ; \({P}_{j,\Delta t}\) is the pressure calculated in the node j for the instant \(\Delta t\) ; \({P}^{min}\) is the minimum pressure of service, pre-established by the user, for any node of the network; and \({N}_{valve,\Delta t}\) is the number of valves calculated at instant \(\Delta t\) .

3.3.4 Minimization of Excess Nodal Pressure

In this case, the objective is to reduce the nodal pressure when it overcomes a threshold value, in order to protect the pipes and equipment in the network. The suggested definition of the objective function to be minimized is as follows:

where N n is the number of demand nodes; \(P{e}_{j}\) is the excess pressure at node j ; \({P}_{j,\Delta t}\) is the pressure of node j at time \(\Delta t\) ;  \({P}^{max}\) is the maximum node pressure limit; and C ep is the excess node pressure penalty constant, with the following constraints:

3.3.5 Maximization of the Reliability

Some authors suggest optimizing pressure distribution in the WDN on the basis of a reliability index, specifically the Nodal Pressure Reliability Index (NPRI). The index can be defined as follows:

where NPRI is the nodal pressure reliability of the network; \({NPRI}_{j,\Delta t}\) is the nodal pressure reliability index of node j at time \(\Delta t;\) \({P}_{j,\Delta t}\) is the nodal pressure at time \(\Delta t\)  in meter, Nn is the number of nodes; and \(Q_{j,\Delta t}^{req}\) is the demand of node j at time \(\Delta t\) . Another interpretation of the use of the reliability index for optimizing water network pressures is the Fuzzy Reliability Index (FRI), defined as follows:

where FRI is the fuzzy reliability index of the water distribution network; FRI Node is the total nodal fuzzy reliability; FRI Pipe is the total fuzzy reliability of the pipes; Nn 35 is the number of nodes with pressure higher than 35 m; i  and j are counters for pipes and nodes, respectively; NL and Nn are the total number of pipes and nodes, respectively; Q req j is the demand at node j; L i is the length of i-th pipe; \(MemF_{pipe,i}\)  is the membership function of pipe i to the pipe fuzzy reliability function; MemF Node,j is the membership function of the node j to the nodal fuzzy reliability function; P j is the pressure head at node j; h fi is the head loss per 1 km length of pipe, as computed by the Hazen-Williams equation; Q i discharge in pipe i; D i is the diameter of pipe i; and CHW i is the Hazen Williams coefficient of pipe i . In this case, the OF is subjected to the following constraints:

\({P}^{set,min}\) and \({P}^{set,max}\) are the minimum and maximum possible PRV set pressures, \({P}_{valve}^{set}\) is the set pressure of each valve, and NPRV is the number of PRV.

3.3.6 Maximization of the Resilience

This is an objective function that can be used for networks partitioned into districts. The index used as an objective function is the resilience deviation index \({I}_{RD}\) , which compares pressures before and after the network partitioning operation, i.e., after the installation of a control valve. It is defined as:

where Q j is the total water demand at node j , including the pressure-dependent leakage flow; \({P}^{min}\) is the minimum pressure required for proper supply; \({P}_{j,nd}\) and \({P}_{j}\) are the total heads detected at the same node in the starting configuration of the WDN and in the partitioned one, respectively.

3.3.7 Maximizing the Demand Uniformity throughout the Network

This objective function is used when valves are placed in order to create a District Metered Area (DMA). The objective is to obtain a DMA where the demand has the highest possible uniformity. The uniformity is evaluated using the coefficient of variation \({\text{C}}{\text{u}}\) . The lower \({\text{C}}{\text{u}}\) is, the more uniform is the demand across the DMAs:

where \(std ({Q}_{j}^{req})\) is the standard deviation of the demands in the area considered, and \(average({Q}_{j}^{req})\) is the average of the demands in the area considered.

3.3.8 Maximization of Energy Recovery

Energy recovery and saving are strongly connected to valve placement in the WDN. In fact, every time a control valve is installed in a WDN, a minor loss is introduced in the pipeline. Where this loss is particularly intense, some researchers suggest to install energy recovery devices in place of simple pressure reducing valves. Among the devices most commonly proposed in place of PRVs for energy recovery purposes are Pumps As Turbines (PATs) (See Table 2  for reference details). In these cases, the objective function is devoted to the optimization of the recovered energy. The energy recovered can be translated into a revenue introducing an electrical energy tariff \({t}_{e}\) :

where ρ is the water density; g is the gravitational acceleration; \({Q}_{k}^{*}\) is the flow at k-th PAT at timestep \(\Delta t\) ; H k is the head available for recovery at k-th PAT at timestep \(\Delta t\) ; \({\eta }_{k}\) is the efficiency of the k-th PAT; and \({N}_{PAT}\) is the number of PATs installed in the water network.

An alternative solution is to introduce an objective function that also considers the volume of water saved thanks to the regulation of pressure made possible by the PATs introduced in the networks. This alternative solutions ranks the solutions based on the most cost-effective combination of energy recovery (based on total daily energy recovered) and leakage reduction (average percentage leakage reduction), according to the following equation:

where W ER is the energy recovery weight; \({t}_{e}\) is the energy cost; \(ER_{\Delta t}\)  is the energy recovery per timestep; \({W}_{L}\) is the current annual real losses; W LR is the leakage reduction weight; \({c}_{{\text{CM}}}\) is the water cost per unit; LR i is the leakage reduction per timestep; ER max is the energy recovery installation capacity; and \({OF}_{pen}\) is the solution penalty defined as follows:

An alternative version of the equation is given by the same authors as follows:

Another issue concerning energy saving is the optimization of pump scheduling, which is not strictly related with valve installation and setting but involves pressure regulation. Researchers applied metaheuristic algorithms also for optimizing pump scheduling. Usually, the objective functions used in these cases are based on the cost, because it is a simple way to put together the water saved from pressure regulation and the energy saved by pump scheduling, which can both be considered as a cost for the utility. An example of this application is represented with the following objective function:

where ω is the water price coefficient, equal to the water price multiplied by the conversion factor. W t ’ and W t are the leakage amount of the \(\Delta t\) period before and after scheduling, respectively. T is the number of time steps. Q mnt is the quantity of the n pump in the m pump station in period \(\Delta t\) . H mnt is the corresponding head. η mnt is the efficiency coefficient, which includes pump efficiency, motor efficiency, etc. ψ m is the electric price coefficient of the m pump station. p and q are the total number of pump stations and the total number of pumps in the m pump station. F before is the total electric consumption before scheduling. Including energy recovery and pressure regulation in the same OF brings to:

where flow discharge \({Q}_{k}\) by the pressure drop  \(\Delta H_k\)   caused by the k-th device, and a is a penalty coefficient defined in Table  1 .

3.4 Case Studies

To test and validate the optimization methodologies developed in their research, the authors introduced several benchmark networks. Some networks are real whereas others are synthetic and specifically designed to the benchmarking scope. An issue that often limits the possible use of the same network by other researchers is the lack of information about the network characteristics. This is the main reason why methods are not applied to the same network as first benchmark, which is a major obstacle to a structured comparison among the different methodologies. An effort in this direction has been made by Creaco and Pezzinga ( 2018 ) and by Ormsbee et al. ( 2022 ): the former compared different optimization methodologies using the same reference network; the latter created an organized database of several networks that can be used for water distribution research activities. A repository is accessible and can be freely used by researchers (University of Kentucky 2022 ).

Table 3 summarizes the different networks used as a case study in the papers considered in this review, illustrating the characteristics of each network along with a sketch of its layout. The initial point to consider is that various networks exhibit distinct characteristics, such as varying numbers of nodes and links, as well as the presence of reservoirs or pumps. This diversity prevents straightforward comparison between the methodologies. The network most used as benchmark case (21 of the total number of paper reviewed) is the one firstly introduced by Coulbeck and Sterling ( 1978 ), inspired from the Yorkshire Water Authority’s network. It is composed by 22 nodes and 37 links highly interconnected and by three reservoirs. The network has been used for the application of several optimization methodologies, in particular GA, PSO, ACO, and, lastly, also AI. Comparing the results obtained by the different methodologies in terms of percentage reduction of leakage, the highest performance solution was found by (Giugni et al. 2014 ), with a reduction of 31% of losses, obtained by installing 3 control valves and using several insulation valves in the network. The methodology is based on a hybrid multi-objective algorithm that composes GA and LP respectively for valve placement and valve setting.

4 Concluding Remarks and Future Directions

Over the last three decades, various research teams have developed their own approaches, algorithms, test networks and optimization variables. Research groups in Italy, the UK, and Iran have been particularly productive on these areas with a particular focus on leakage reduction for Italy and Iran and on energy saving for UK. The results obtained by researchers are promising with respect to the use of metaheuristics as an optimization method for reducing water loss in WDNs and recovering dissipated energy. Despite the proven validity and functionality of all the presented methodologies, at least on the network used as a case study, none has emerged as the final reference method. Nevertheless, there is still much research to be done on reducing computational burdens and integrating prediction models.

The current research trend on metaheuristic methods, highlighted in the most recent publications, such as Karakatsanis and Theodossiou ( 2022 ) and Samadi-Koucheksaraee et al. ( 2022 ), suggests a focus on hybridization, integrating multiple metaheuristic methods to leverage their strengths and overcome their weaknesses. Hybrid algorithms combine the exploration capabilities of Genetic Algorithms with the exploitation abilities of other metaheuristic methods, or combine Machine Learning with different metaheuristic algorithms (Sangroula et al. 2022 ). The development of these methods is linked to the recent high availability of data that can be used in the learning process by Artificial Intelligence methods. In this context, the recent momentum in technology development should also be considered for the development of new technologies for the control and monitoring of networks. These technologies, capable of providing remote control, reliable data, and high-frequency updates, can enable the implementation of new strategies for optimizing loss reduction and energy recovery in water distribution networks.
