ADVERTISEMENTS:

Here is your short essay on Energy!

Energy is a primary input for almost all activities and is, therefore, vital for improvement in quality of life. Its use in sector such as industry, com­merce, transport, telecommunications, wide range of agriculture and house­hold services has compelled us to focus our attention to ensure its continuous supply to meet our ever increasing demands.

Energy related problems are not new. The energy related problems are as old as 2500 years ago. The early Romans and Greeks faced fuel shortage as wood was their primary source of energy. They had to import wood from very faraway places. Fossil fuel is still the main source of energy. Today we are facing the peak of oil and gas utilization. Fossil fuel resources took millions of years to form and are infinite.

These resources may be exhausted in a few hundred years. Historical evidence shows that world energy demand has increased at almost the same rate as gross world product (GWP). People living in industrialized or developed countries are a relatively small percentage of the world’s total popu­lation, but they consume a huge share of the total energy produced in the world.

The main issues regarding the energy problem in urban areas are:

(a) How to utilize the energy from non-renewable sources at their maximum efficiency.

(b) How to make use of renewable sources of energy or the alternative energy sources?

Energy policy today has two choices (paths). One path leads to the fossil fuels (hard path), which means continuing as we have been for a number of years i.e., emphasising energy quantity by finding more amount of fossil fuels and build­ing much larger power plants.

The second path is the soft path which leads to the energy alternatives that emphasize energy quality and are also renewable, flexible and more environmental friendly. The soft path relies mainly on renew­able energy i.e. sunlight, wind biomass, tidal energy etc.

There is a need to resort to energy management. This concept recognizes that no single energy source can possibly provide all the energy required by the source nation. Thus, the basic objective of the integrated energy management is to obtain sustainable energy and which should be realized at the local level. In addition, measures to conserve energy need to be followed.

Energy conservation is considered as a quick and economical way to solve the problem of power shortage as also a means of conserving the country’s finite sources of energy. Energy conservation measures are cost effective, require rela­tively small investments and have short gestation as well as pay back periods. The studies conducted by Energy Management Centre, New Delhi have indi­cated that there is about 25% potential of energy conservation in the industrial sector.

• Renewable and nonrenewable energy resources

Renewable and nonrenewable energy sources

• Global energy use
• Intro to energy resources and consumption

• Nonrenewable energy sources are those that are consumed faster than they can be replaced. Nonrenewable energy sources include nuclear energy as well as fossil fuels such as coal, crude oil, and natural gas. These energy sources have a finite supply, and often emit harmful pollutants into the environment.
• Renewable energy sources are those that are naturally replenished on a relatively short timescale. Renewable energy sources include solar, wind, hydroelectric, and geothermal energy. They also include biomass and hydrogen fuels. These energy sources are sustainable and generate fewer greenhouse gas emissions than fossil fuels.

Renewable energy, explained

Solar, wind, hydroelectric, biomass, and geothermal power can provide energy without the planet-warming effects of fossil fuels.

In any discussion about climate change , renewable energy usually tops the list of changes the world can implement to stave off the worst effects of rising temperatures. That's because renewable energy sources such as solar and wind don't emit carbon dioxide and other greenhouse gases that contribute to global warming .

Clean energy has far more to recommend it than just being "green." The growing sector creates jobs , makes electric grids more resilient, expands energy access in developing countries, and helps lower energy bills. All of those factors have contributed to a renewable energy renaissance in recent years, with wind and solar setting new records for electricity generation .

For the past 150 years or so, humans have relied heavily on coal, oil, and other fossil fuels to power everything from light bulbs to cars to factories. Fossil fuels are embedded in nearly everything we do, and as a result, the greenhouse gases released from the burning of those fuels have reached historically high levels .

As greenhouse gases trap heat in the atmosphere that would otherwise escape into space, average temperatures on the surface are rising . Global warming is one symptom of climate change, the term scientists now prefer to describe the complex shifts affecting our planet’s weather and climate systems. Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas , and a range of other impacts .

Of course, renewables—like any source of energy—have their own trade-offs and associated debates. One of them centers on the definition of renewable energy. Strictly speaking, renewable energy is just what you might think: perpetually available, or as the U.S. Energy Information Administration puts it, " virtually inexhaustible ." But "renewable" doesn't necessarily mean sustainable, as opponents of corn-based ethanol or large hydropower dams often argue. It also doesn't encompass other low- or zero-emissions resources that have their own advocates, including energy efficiency and nuclear power.

Types of renewable energy sources

Hydropower: For centuries, people have harnessed the energy of river currents, using dams to control water flow. Hydropower is the world's biggest source of renewable energy by far, with China, Brazil, Canada, the U.S., and Russia the leading hydropower producers . While hydropower is theoretically a clean energy source replenished by rain and snow, it also has several drawbacks.

For Hungry Minds

Large dams can disrupt river ecosystems and surrounding communities , harming wildlife and displacing residents. Hydropower generation is vulnerable to silt buildup, which can compromise capacity and harm equipment. Drought can also cause problems. In the western U.S., carbon dioxide emissions over a 15-year period were 100 megatons higher than they normally would have been, according to a 2018 study , as utilities turned to coal and gas to replace hydropower lost to drought. Even hydropower at full capacity bears its own emissions problems, as decaying organic material in reservoirs releases methane.

Dams aren't the only way to use water for power: Tidal and wave energy projects around the world aim to capture the ocean's natural rhythms. Marine energy projects currently generate an estimated 500 megawatts of power —less than one percent of all renewables—but the potential is far greater. Programs like Scotland’s Saltire Prize have encouraged innovation in this area.

Wind: Harnessing the wind as a source of energy started more than 7,000 years ago . Now, electricity-generating wind turbines are proliferating around the globe, and China, the U.S., and Germany are the leading wind energy producers. From 2001 to 2017 , cumulative wind capacity around the world increased to more than 539,000 megawatts from 23,900 mw—more than 22 fold.

Some people may object to how wind turbines look on the horizon and to how they sound, but wind energy, whose prices are declining , is proving too valuable a resource to deny. While most wind power comes from onshore turbines, offshore projects are appearing too, with the most in the U.K. and Germany. The first U.S. offshore wind farm opened in 2016 in Rhode Island, and other offshore projects are gaining momentum . Another problem with wind turbines is that they’re a danger for birds and bats, killing hundreds of thousands annually , not as many as from glass collisions and other threats like habitat loss and invasive species, but enough that engineers are working on solutions to make them safer for flying wildlife.

Solar: From home rooftops to utility-scale farms, solar power is reshaping energy markets around the world. In the decade from 2007 and 2017 the world's total installed energy capacity from photovoltaic panels increased a whopping 4,300 percent .

In addition to solar panels, which convert the sun's light to electricity, concentrating solar power (CSP) plants use mirrors to concentrate the sun's heat, deriving thermal energy instead. China, Japan, and the U.S. are leading the solar transformation, but solar still has a long way to go, accounting for around two percent of the total electricity generated in the U.S. in 2017. Solar thermal energy is also being used worldwide for hot water, heating, and cooling.

Biomass: Biomass energy includes biofuels such as ethanol and biodiesel , wood and wood waste, biogas from landfills, and municipal solid waste. Like solar power, biomass is a flexible energy source, able to fuel vehicles, heat buildings, and produce electricity. But biomass can raise thorny issues.

Critics of corn-based ethanol , for example, say it competes with the food market for corn and supports the same harmful agricultural practices that have led to toxic algae blooms and other environmental hazards. Similarly, debates have erupted over whether it's a good idea to ship wood pellets from U.S. forests over to Europe so that it can be burned for electricity. Meanwhile, scientists and companies are working on ways to more efficiently convert corn stover , wastewater sludge , and other biomass sources into energy, aiming to extract value from material that would otherwise go to waste.

Geothermal: Used for thousands of years in some countries for cooking and heating, geothermal energy is derived from the Earth’s internal heat . On a large scale, underground reservoirs of steam and hot water can be tapped through wells that can go a mile deep or more to generate electricity. On a smaller scale, some buildings have geothermal heat pumps that use temperature differences several feet below ground for heating and cooling. Unlike solar and wind energy, geothermal energy is always available, but it has side effects that need to be managed, such as the rotten egg smell that can accompany released hydrogen sulfide.

Ways to boost renewable energy

Cities, states, and federal governments around the world are instituting policies aimed at increasing renewable energy. At least 29 U.S. states have set renewable portfolio standards —policies that mandate a certain percentage of energy from renewable sources, More than 100 cities worldwide now boast at least 70 percent renewable energy, and still others are making commitments to reach 100 percent . Other policies that could encourage renewable energy growth include carbon pricing, fuel economy standards, and building efficiency standards. Corporations are making a difference too, purchasing record amounts of renewable power in 2018.

Wonder whether your state could ever be powered by 100 percent renewables? No matter where you live, scientist Mark Jacobson believes it's possible. That vision is laid out here , and while his analysis is not without critics , it punctuates a reality with which the world must now reckon. Even without climate change, fossil fuels are a finite resource, and if we want our lease on the planet to be renewed, our energy will have to be renewable.

ENCYCLOPEDIC ENTRY

Renewable resources.

Renewable resources are an energy source that cannot be depleted and are able to supply a continuous source of clean energy.

Geology, Earth Science, Engineering, Physics

Geothermal power is a form of renewable energy created by powering electrical generators with the heat of the earth and naturally occurring subterranean hot water reservoirs.

When it comes to energy resources, there is always the question of sustainability. It is important that resources provide enough energy to meet our needs—to heat our houses, power our cities, and run our cars. However, it is also important to consider how these resources can be used long term. Some resources will practically never run out. These are known as renewable resources . Renewable resources also produce clean energy , meaning less pollution and greenhouse gas emissions, which contribute to climate change.

The United States’ energy sources have evolved over time, from using wood prior to the 19th century to later adopting nonrenewable resources, such as fossil fuels, petroleum, and coal, which are still the dominant sources of energy today. But Earth has a limited supply of these resources. Recently, renewable resource use has begun to increase. According to the U.S. Environmental Protection Agency, 11 percent of the nation's energy consumption came from renewable resources in 2017.

There are some challenges associated with using renewable resources . For instance, renewable energy can be less reliable than non renewable energy , with seasonal or even daily changes in the amount produced. However, scientists are continually addressing these challenges, working to improve feasibility and reliability of renewable resources .

Renewable resources include  biomass energy (such as ethanol ), hydropower, geothermal power , wind energy , and solar energy .

Biomass refers to organic material from plants or animals. This includes wood, sewage, and ethanol (which comes from corn or other plants). Biomass can be used as a source of energy because this organic material has absorbed energy from the Sun. This energy is, in turn, released as heat energy when burned.

Hydropower is one of the oldest renewable resources and has been used for thousands of years. Today, every U.S. state uses some amount of hydroelectricity. With hydropower, the mechanical energy from flowing water is used to generate electricity. Hydroelectric power plants use the flow of rivers and streams to turn a turbine to power a generator, releasing electricity.

Geothermal energy comes from the heat generated deep within Earth’s core. Geothermal reservoirs can be found at tectonic plate boundaries near volcanic activity or deep underground. Geothermal energy can be harnessed by drilling wells to pump hot water or steam to a power plant . This energy is then used for heating and electricity.

Wind energy generates electricity by turning wind turbines . The wind pushes the turbine’s blades, and a generator converts this mechanical energy into electricity. This electricity can supply power to homes and other buildings, and it can even be stored in the power grid .

Radiation from the sun can be used as a power source as well. Photovoltaic cells can be used to convert this solar energy into electricity. Individually, these cells only generate enough energy to power a calculator, but when combined to create solar panels or even larger arrays, they provide much more electricity.

Searching for the right method of using renewable resources is a task that is growing ever more important as Earth’s supply of nonrenewable resources continues to dwindle. Converting to renewable energy will not only better sustain the world’s rapidly growing population, but it will also provide a cleaner, healthier environment for the generations to come.

The classical description of energy is the ability of a system to perform work, but as energy exists in so many forms, it is hard to find one comprehensive definition. It is the property of an object that can be transferred from one object to another or converted to different forms but cannot be created or destroyed. There are numerous sources of energy. In the next few sections, let us discuss the about different sources of energy in detail.

Sources Of Energy

Sources of energy can be classified into:

• Renewable Sources
• Non-renewable Sources

Renewable sources of energy are available plentiful in nature and are sustainable. These resources of energy can be naturally replenished and are safe for the environment.

Examples of renewable sources of energy are : Solar energy, geothermal energy, wind energy, biomass, hydropower and tidal energy.

A non-renewable resource is a natural resource that is found underneath the earth. These type of energy resources do not replenish at the same speed at which it is used. They take millions of years to replenish. The main examples of non-renewable resources are coal, oil and natural gas.

Examples of non-renewable sources of energy are: Natural gas, coal, petroleum, nuclear energy and hydrocarbon gas liquids.

Difference between Renewable and Non-renewable Sources of Energy

Natural sources of energy.

During the stone age, it was wood. During the iron age, we had coal. In the modern age, we have fossil fuels like petroleum and natural gas. So how do we choose the source of energy?

Good sources of energy should have the following qualities:

• Optimum heat production per unit of volume/mass used
• Easy to transport
• Least Polluting

What is renewable energy?

Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly being replenished. Renewable energy sources are plentiful and all around us.

Fossil fuels - coal, oil and gas - on the other hand, are non-renewable resources that take hundreds of millions of years to form. Fossil fuels, when burned to produce energy, cause harmful greenhouse gas emissions, such as carbon dioxide.

Generating renewable energy creates far lower emissions than burning fossil fuels. Transitioning from fossil fuels, which currently account for the lion’s share of emissions, to renewable energy is key to addressing the climate crisis.

Renewables are now cheaper in most countries, and generate three times more jobs than fossil fuels.

Here are a few common sources of renewable energy:

SOLAR ENERGY

Solar energy is the most abundant of all energy resources and can even be harnessed in cloudy weather. The rate at which solar energy is intercepted by the Earth is about 10,000 times greater than the rate at which humankind consumes energy.

Solar technologies can deliver heat, cooling, natural lighting, electricity, and fuels for a host of applications. Solar technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation.

Although not all countries are equally endowed with solar energy, a significant contribution to the energy mix from direct solar energy is possible for every country.

The cost of manufacturing solar panels has plummeted dramatically in the last decade, making them not only affordable but often the cheapest form of electricity. Solar panels have a lifespan of roughly 30 years , and come in variety of shades depending on the type of material used in manufacturing.

WIND ENERGY

Wind energy harnesses the kinetic energy of moving air by using large wind turbines located on land (onshore) or in sea- or freshwater (offshore). Wind energy has been used for millennia, but onshore and offshore wind energy technologies have evolved over the last few years to maximize the electricity produced - with taller turbines and larger rotor diameters.

Though average wind speeds vary considerably by location, the world’s technical potential for wind energy exceeds global electricity production, and ample potential exists in most regions of the world to enable significant wind energy deployment.

Many parts of the world have strong wind speeds, but the best locations for generating wind power are sometimes remote ones. Offshore wind power offers t remendous potential .

GEOTHERMAL ENERGY

Geothermal energy utilizes the accessible thermal energy from the Earth’s interior. Heat is extracted from geothermal reservoirs using wells or other means.

Reservoirs that are naturally sufficiently hot and permeable are called hydrothermal reservoirs, whereas reservoirs that are sufficiently hot but that are improved with hydraulic stimulation are called enhanced geothermal systems.

Once at the surface, fluids of various temperatures can be used to generate electricity. The technology for electricity generation from hydrothermal reservoirs is mature and reliable, and has been operating for more than 100 years .

Hydropower harnesses the energy of water moving from higher to lower elevations. It can be generated from reservoirs and rivers. Reservoir hydropower plants rely on stored water in a reservoir, while run-of-river hydropower plants harness energy from the available flow of the river.

Hydropower reservoirs often have multiple uses - providing drinking water, water for irrigation, flood and drought control, navigation services, as well as energy supply.

Hydropower currently is the largest source of renewable energy in the electricity sector. It relies on generally stable rainfall patterns, and can be negatively impacted by climate-induced droughts or changes to ecosystems which impact rainfall patterns.

The infrastructure needed to create hydropower can also impact on ecosystems in adverse ways. For this reason, many consider small-scale hydro a more environmentally-friendly option , and especially suitable for communities in remote locations.

OCEAN ENERGY

Ocean energy derives from technologies that use the kinetic and thermal energy of seawater - waves or currents for instance -  to produce electricity or heat.

Ocean energy systems are still at an early stage of development, with a number of prototype wave and tidal current devices being explored. The theoretical potential for ocean energy easily exceeds present human energy requirements.

Bioenergy is produced from a variety of organic materials, called biomass, such as wood, charcoal, dung and other manures for heat and power production, and agricultural crops for liquid biofuels. Most biomass is used in rural areas for cooking, lighting and space heating, generally by poorer populations in developing countries.

Modern biomass systems include dedicated crops or trees, residues from agriculture and forestry, and various organic waste streams.

Energy created by burning biomass creates greenhouse gas emissions, but at lower levels than burning fossil fuels like coal, oil or gas. However, bioenergy should only be used in limited applications, given potential negative environmental impacts related to large-scale increases in forest and bioenergy plantations, and resulting deforestation and land-use change.

Energy Conservation Essay for Students and Children

500 words energy conservation essay.

Energy conservation refers to the efforts made to reduce the consumption of energy. The energy on Earth is not in unlimited supply. Furthermore, energy can take plenty of time to regenerate. This certainly makes it essential to conserve energy. Most noteworthy, energy conservation is achievable either by using energy more efficiently or by reducing the amount of service usage.

Importance of Energy Conservation

First of all, energy conservation plays an important role in saving non-renewable energy resources. Furthermore, non-renewable energy sources take many centuries to regenerate. Moreover, humans consume energy at a faster rate than it can be produced. Therefore, energy conservation would lead to the preservation of these precious non-renewable sources of energy.

Energy conservation will reduce the expenses related to fossil fuels. Fossil fuels are very expensive to mine. Therefore, consumers are required to pay higher prices for goods and services. Energy conservation would certainly reduce the amount of fossil fuel being mined. This, in turn, would reduce the costs of consumers.

Consequently, energy conservation would strengthen the economy as consumers will have more disposable income to spend on goods and services.

Energy conservation is good for scientific research. This is because; energy conservation gives researchers plenty of time to conduct researches.

Therefore, these researchers will have more time to come up with various energy solutions and alternatives. Humans must ensure to have fossil fuels as long as possible. This would give me enough time to finding practical solutions.

Another important reason for energy conservation is environmental protection. This is because various energy sources are significantly harmful to the environment. Furthermore, the burning of fossil fuels considerably pollutes the atmosphere. Moreover, nuclear energy creates dangerous nuclear waste. Hence, energy conservation will lead to environmental protection.

Energy conservation would also result in the good health of humans. Furthermore, the pollution released due to energy sources is harmful to the human body. The air pollution due to fossil fuels can cause various respiratory problems. Energy sources can pollute water which could cause several harmful diseases in humans. Nuclear waste can cause cancer and other deadly problems in the human body.

Measures to Conserve Energy

Energy taxation is a good measure from the government to conserve energy. Furthermore, several countries apply energy or a carbon tax on energy users. This tax would certainly put pressure on energy users to reduce their energy consumption. Moreover, carbon tax forces energy users to shift to other energy sources that are less harmful.

Building design plays a big role in energy conservation. An excellent way to conserve energy is by performing an energy audit in buildings. Energy audit refers to inspection and analysis of energy use in a building. Most noteworthy, the aim of the energy audit is to appropriately reduce energy input.

Another important way of energy conservation is by using energy-efficient products. Energy-efficient products are those that use lesser energy than their normal counterparts. One prominent example can be using an energy-efficient bulb rather than an incandescent light bulb.

In conclusion, energy conservation must be among the utmost priorities of humanity. Mahatma Gandhi was absolutely right when he said, “the earth provides enough to satisfy every man’s needs but not every man’s greed”. This statement pretty much sums up the importance of energy conservation. Immediate implementation of energy conservation measures is certainly of paramount importance.

FAQs on Energy Conservation

Q1 state one way in which energy conservation is important.

A1 One way in which energy conservation is important is that it leads to the preservation of fossil fuels.

Q2 Why energy taxation is a good measure to conserve energy?

A2 Energy taxation is certainly a good measure to conserve energy. This is because energy taxation puts financial pressure on energy users to reduce their energy consumption.

This Is the Future: Essay on Renewable Energy

Today the world population depends on nonrenewable energy resources. With the constantly growing demand for energy, natural gas, coal, and oil get used up and cannot replenish themselves. 

Aside from limited supply, heavy reliance on fossil fuels causes planetary-scale damage. Sea levels are rising. Heat-trapping carbon dioxide increased the warming effect by 45% from 1990 to 2019. The only way to tackle the crisis is to start the transition to renewable energy now. 

What is renewable energy? It is energy that comes from replenishable natural resources like sunlight, wind, thermal energy, moving water, and organic materials. Renewable resources do not run out. They are cost-efficient and renew faster than they are consumed. How does renewable energy save money? It creates new jobs, supports economic growth, and decreases inequitable fossil fuel subsidies. 

At the current rates of production, some fossil fuels will not even last another century. This is why the future depends on reliable and eco-friendly resources. This renewable energy essay examines the types and benefits of renewable energy and its role in creating a sustainable future.

Top 5 Types of Renewable Energy: The Apollo Alliance Rankings

There are many natural resources that can provide people with clean energy. To make a list of the five most booming types of renewable energy on the market today, this energy essay uses data gathered by the Apollo Alliance. It is a project that aims to revolutionize the energy sector of the US with a focus on clean energy. 

The Apollo Alliance unites businesses, community leaders, and environmental experts to support the transition to more sustainable and efficient living. Their expert opinion helped to compile information about the most common and cost-competitive sources of renewable energy. However, if you want to get some more in-depth research, you can entrust it to an essay writer . Here’s a quick overview of renewable energy resources that have a huge potential to substitute fossil fuels. 

Solar Renewable Energy

The most abundant and practically endless resource is solar energy. It can be turned into electricity by photovoltaic systems that convert radiant energy captured from sunlight. Solar farms could generate enough energy for thousands of homes.

An endless supply is the main benefit of solar energy. The rate at which the Earth receives it is 10,000 times greater than people can consume it, as a paper writer points out based on their analysis of research findings. It can substitute fossil fuels and deliver people electricity, hot water, cooling, heat, etc. 

The upfront investment in solar systems is rather expensive. This is one of the primary limitations that prevent businesses and households from switching to this energy source at once. However, the conclusion of solar energy is still favorable. In the long run, it can significantly decrease energy costs. Besides, solar panels are gradually becoming more affordable to manufacture and adopt, even at an individual level. 

Wind Renewable Energy

Another clean energy source is wind. Wind farms use the kinetic energy of wind flow to convert it into electricity. The Appolo Alliance notes that, unlike solar farms, they can’t be placed in any location. To stay cost-competitive, wind farms should operate in windy areas. Although not all countries have the right conditions to use them on a large scale, wind farms might be introduced for some energy diversity. The technical potential for it is still tremendous. 

Wind energy is clean and safe for the environment. It does not pollute the atmosphere with any harmful products compared to nonrenewable energy resources. 

The investment in wind energy is also economically wise. If you examine the cost of this energy resource in an essay on renewable resources, you’ll see that wind farms can deliver electricity at a price lower than nonrenewable resources. Besides, since wind isn’t limited, its cost won’t be influenced by the imbalance of supply and demand.

Geothermal Renewable Energy

Natural renewable resources are all around us, even beneath the ground. Geothermal energy can be produced from the thermal energy from the Earth’s interior. Sometimes heat reaches the surface naturally, for example, in the form of geysers. But it can also be used by geothermal power plants. The Earth’s heat gets captured and converted to steam that turns a turbine. As a result, we get geothermal energy.

This source provides a significant energy supply while having low emissions and no significant footprint on land. A factsheet and essay on renewable resources state that geothermal plants will increase electricity production from 17 billion kWh in 2020 to 49.8 billion kWh in 2050.

However, this method is not without limitations. While writing a renewable resources essay, consider that geothermal energy can be accessed only in certain regions. Geological hotspots are off-limits as they are vulnerable to earthquakes. Yet, the quantity of geothermal resources is likely to grow as technology advances. 

Ocean Renewable Energy

The kinetic and thermal energy of the ocean is a robust resource. Ocean power systems rely on:

• Changes in sea level;
• Wave energy;
• Water surface temperatures;
• The energy released from seawater and freshwater mixing.

Ocean energy is more predictable compared to other resources. As estimated by EPRI, it has the potential to produce 2640 TWh/yr. However, an important point to consider in a renewable energy essay is that the kinetic energy of the ocean varies. Yet, since it is ruled by the moon’s gravity, the resource is plentiful and continues to be attractive for the energy industry. 

Wave energy systems are still developing. The Apollo energy corporation explores many prototypes. It is looking for the most reliable and robust solution that can function in the harsh ocean environment. 

Another limitation of ocean renewable energy is that it may cause disruptions to marine life. Although its emissions are minimal, the system requires large equipment to be installed in the ocean. 

Biomass Renewable Energy

Organic materials like wood and charcoal have been used for heating and lighting for centuries. There are a lot more types of biomass: from trees, cereal straws, and grass to processed waste. All of them can produce bioenergy. 

Biomass can be converted into energy through burning or using methane produced during the natural process of decomposition. In an essay on renewable sources of energy, the opponents of the method point out that biomass energy is associated with carbon dioxide emissions. Yet, the amount of released greenhouse gases is much lower compared to nonrenewable energy use. 

While biomass is a reliable source of energy, it is only suitable for limited applications. If used too extensively, it might lead to disruptions in biodiversity, a negative impact on land use, and deforestation. Still, Apollo energy includes biomass resources that become waste and decompose quickly anyway. These are organic materials like sawdust, chips from sawmills, stems, nut shells, etc. 

What Is the Apollo Alliance?

The Apollo Alliance is a coalition of business leaders, environmental organizations, labor unions, and foundations. They all unite their efforts in a single project to harness clean energy in new, innovative ways. 

Why Apollo? Similarly to President John F. Kennedy’s Apollo Project, Apollo energy is a strong visionary initiative. It is a dare, a challenge. The alliance calls for the integrity of science, research, technology, and the public to revolutionize the energy industry.

The project has a profound message. Apollo energy solutions are not only about the environment or energy. They are about building a new economy. The alliance gives hope to building a secure future for Americans. 

What is the mission of the Apollo Alliance? 

• Achieve energy independence with efficient and limitless resources of renewable energy.
• Pioneer innovation in the energy sector.
• Build education campaigns and communication to inspire new perceptions of energy. 
• Create new jobs.
• Reduce dependence on imported fossil fuels. 
• Build healthier and happier communities. 

The transformation of the industry will lead to planet-scale changes. The Apollo energy corporation can respond to the global environmental crisis and prevent climate change. 

Apollo renewable energy also has the potential to become a catalyst for social change. With more affordable energy and new jobs in the industry, people can bridge the inequality divide and build stronger communities. 

Why Renewable Energy Is Important for the Future

Renewable energy resources have an enormous potential to cover people’s energy needs on a global scale. Unlike fossil fuels, they are available in abundance and generate minimal to no emissions. 

The burning of fossil fuels caused a lot of environmental problems—from carbon dioxide emissions to ocean acidification. Research this issue in more detail with academic assistance from essay writer online . You can use it to write an essay on renewable sources of energy to explain the importance of change and its global impact. 

Despite all the damage people caused to the planet, there’s still hope to mitigate further repercussions. Every renewable energy essay adds to the existing body of knowledge we have today and advances research in the field. Here are the key advantages and disadvantages of alternative energy resources people should keep in mind. 

Advantage of Green Energy

The use of renewable energy resources has a number of benefits for the climate, human well-being, and economy:

• Renewable energy resources have little to no greenhouse gas emissions. Even if we take into account the manufacturing and recycling of the technologies involved, their impact on the environment is significantly lower compared to fossil fuels. 
• Renewable energy promotes self-sufficiency and reduces a country’s dependence on foreign fuel. According to a study, a 1% increase in the use of renewable energy increases economic growth by 0.21%. This gives socio-economic stability.
• Due to a lack of supply of fossil fuels and quick depletion of natural resources, prices for nonrenewable energy keep increasing. In contrast, green energy is limitless and can be produced locally. In the long run, this allows decreasing the cost of energy. 
• Unlike fossil fuels, renewable energy doesn’t emit air pollutants. This positively influences health and quality of life. 
• The emergence of green energy plants creates new jobs. Thus, Apollo energy solutions support the growth of local communities. By 2030, the transition to renewable energy is expected to generate 10.3 million new jobs. 
• Renewable energy allows decentralization of the industry. Communities get their independent sources of energy that are more flexible in terms of distribution. 
• Renewable energy supports equality. It has the potential to make energy more affordable to low-income countries and expand access to energy even in remote and less fortunate neighborhoods. 

Disadvantages of Non-Conventional Energy Sources

No technology is perfect. Renewable energy resources have certain drawbacks too: 

• The production of renewable energy depends on weather conditions. For example, wind farms could be effective only in certain locations where the weather conditions allow it. The weather also makes it so that renewable energy cannot be generated around the clock. 
• The initial cost of renewable energy technology is expensive. Both manufacturing and installation require significant investment. This is another disadvantage of renewable resources. It makes them unaffordable to a lot of businesses and unavailable for widespread individual use. In addition, the return on investment might not be immediate.
• Renewable energy technology takes up a lot of space. It may affect life in the communities where these clean energy farms are installed. They may also cause disruptions to wildlife in the areas. 
• One more limitation a renewable resources essay should consider is the current state of technology. While the potential of renewable energy resources is tremendous, the technology is still in its development phase. Therefore, renewable energy might not substitute fossil fuels overnight. There’s a need for more research, investment, and time to transition to renewable energy completely. Yet, some diversity of energy resources should be introduced as soon as possible. 
• Renewable energy resources have limited emissions, but they are not entirely pollution-free. The manufacturing process of equipment is associated with greenhouse gas emissions while, for example, the lifespan of a wind turbine is only 20 years. 

For high school seniors eyeing a future rich with innovative endeavors in renewable energy or other fields, it's crucial to seek financial support early on. Explore the top 10 scholarships for high school seniors to find the right fit that can propel you into a future where you can contribute to the renewable energy movement and beyond. Through such financial support, the road to making meaningful contributions to a sustainable future becomes a tangible reality.

Renewable energy unlocks the potential for humanity to have clean energy that is available in abundance. It leads us to economic growth, independence, and stability. With green energy, we can also reduce the impact of human activity on the environment and stop climate change before it’s too late. 

So what’s the conclusion of renewable energy? Transitioning to renewable energy resources might be challenging and expensive. However, most experts agree that the advantages of green energy outweigh any drawbacks. Besides, since technology is continuously evolving, we’ll be able to overcome most limitations in no time.

Essay on Energy Resources in India

The below mentioned essay provides an anatomy of the Energy Resources of India. After reading this essay you will learn about: 1. Introduction to Energy Resources 2. Types of Energy Resource in India 3. The Energy Strategy 4. Energy Scenario.

Essay # Introduction to Energy Resources in India:

Energy resources are very much important in the context of economic development of the country. With the growing industrialisation, mechanisation of agriculture, and the development of transportation sector, the demand for energy resources is increasing day by day.

Thus a positive correlation exists between economic growth and demand for energy. Moreover, consumption of energy for domestic uses and public lighting has also been increasing.

In India between 1952-53 to 1987-88 the GDP had increased annually at the rate of 3.7 per cent while the energy consumption had increased at the rate of 6.2 per cent per annum. Inspite of this, the per capita consumption of energy in India is low in comparison to that of developed countries. In India, more than half of the population does not possess the capacity to purchase commercial energy.

ADVERTISEMENTS:

Again out of the total energy consumed, about half of it is obtained from non-commercial energy. In India the non­commercial sources of energy, mostly used by rural poor, are obtained from firewood, dung cakes and agricultural waste. But the commercial energy is obtained from oil and natural gas, coal, hydro-electricity and a little volume of nuclear energy.

Essay # Types of Energy Resource in India:

Oil and coal :.

In India the consumption of commercial energy is too much dependent on oil and coal. About 47 per cent of the demand for commercial energy is met through petroleum oil. With the growing oil crisis, the importance of coal has also been realised in the country. Coal has an advantage over other fuels as it can be suitably converted into other types of energy like electricity, oil and gas.

In India, the coal is the principal source of electricity, at present with the significant development of thermal power projects based on coal. About 60 per cent of the total electricity generated in India is available from these coal based thermal power projects. 

Power or electricity is considered as one of the major sources of commercial energy. Power contributed about 28.7 per cent of the total commercial energy consumption of the country in 1987-88. In India, the development of power is progressing at a considerable scale.

If we look at the installed capacity then the total installed generating capacity in India has increased from 2,300 M.W. in 1950 to 2,55,000 MW in 2015 (March).

Essay # The Energy Strategy in India:

Out of this total power generation in India about 60 per cent of it is generated through coal-based thermal power projects. The remaining 40 per cent of electricity is generated through hydro-electricity and atomic energy.

Considering the present power scenario of the country and the present energy crisis, proper steps should be taken for the proper utilisation of huge hydro-power potential of the country, which according to C.E.A. is equivalent to 75,400 M.W., along-with the development of non-conventional energy in the country.

The following elements are incorporated in the new energy strategy of the country:

(i) Accelerated exploitation of domestic conventional energy resources—oil, natural gas, coal, hydro, and nuclear power;

(ii) Proper management of oil demand;

(iii) Substitution of natural gas for oil products;

(iv) Conservation of energy;

(v) Exploitation of renewable sources of energy such as energy forestry and bio-gas, specially for meeting the energy requirements of the rural people; and

(vi) Intensify research and development on the emerging energy technologies.

In India, the shortage of energy is presently working as a major constraint of the industrial development. In view of the serious oil crisis faced at present due to soaring oil price, steps be taken for sustained increase in the production of coal.

Hydro-power potential should also be developed with a sense of urgency. Nuclear power, which is at present contributing a little more than 2 per cent of the total power generated, will have to be exploited with great vigour and urgency.

Moreover, in order to supplement the commercial energy produced in the country through the development of non-conventional energy, the Seventh Plan puts emphasis on “The development and accelerated utilisation of renewable energy sources wherever they are technically and economically viable, to improve the access to and availability of, renewable decentralised energy sources, particularly for the rural population and to reduce environment degradation resulting from deforestation.”

In order to realise these above mentioned objectives, the following efforts should be undertaken:

1. A large number of demonstration projects should be undertaken to popularise these new and renewable sources of non-conventional energy like wind, solar, bio-gas and bio-mass.

2. For developing indigenous technologies in this connection, the Government should support intensive R&D (Research and Development).

3. Attempts have to be made to create demand for this system through government intervention along with appropriate financial incentives as the initial cost of this system of renewable energy is very high.

4. An appropriate infrastructure for manufacturing, installation and servicing of this renewable energy system should be developed for its proper utilisation.

5. A large scale awareness programme should be undertaken to educate the people about the new technologies developed for the efficient utilisation of this system.

6. Lastly, substitution of non-commercial energy sources by commercial fuels should be discouraged and for that energy forestry should be developed.

Essay # Energy Scenario in India:

It is important to look at the present energy scenario of the country vis-a-vis other countries.

Latest finding from the Emerging Economy Report prepared by research and consultancy firm, Center for Knowledge Societies (CKS) shows that emerging economies could play pivotal roles in reducing the growing environmental anxieties worldwide. The report shows that most emerging economies remain for below the energy consumption as well as carbon emission levels of industrialised countries.

India’s per capita energy consumption of 12.6 million BTU and Indonesia’s (21.5) are almost negligible when compared to more economically developed nations like South Korea (170.2 m BTU per capita) and Taiwan (181.5 m BTU).

China’s carbon dioxide (CO 2 ) emission of 2.6 thousand metric tonnes per 1000 people is far below the 10.16 thousand metric tonnes per 1000 people in Germany.

The report has also identified several new energy paradigms that can fundamentally alter the ways in which end consumers access and use energy. Therefore, the new paradigm can dramatically change the adverse environmental effects of increased energy demand in the emerging economies.

The report highlighted that energy scarcity can lead to energy efficiency. To some extent the outstanding and latent demand for energy of most emerging economies, which is never met, can contribute to energy efficiency, at least in economic terms.

It is to the credit of India’s growth process that its energy intensity has fallen over time. In comparison to the rest of the world, particularly the emerging economies of Brazil and China, the use of energy per capita in India remained moderate and it increased at a slower pace.

Table 5.3 will clarify its position.

Table 5.3 reveals that total use of energy in India was 362 MMTOE in 1990 and then increased to 573 MMTOE in 2004 as compared to that of 1609 MMTOE for China, 205 MMTOE for Brazil, 1245 MMTOE for EMU and 2326 MMTOE for USA. The growth in the use of energy during the period 1990-2004 was 3.3 per cent in India as compared to that of 3.6 per cent in China, 3.2 per cent in Brazil and 1.4 per cent in USA.

However, the energy use per capita (KGOE) in India was 426 KGOE in 1990 increased to 531 KGOE in 2004 as compared to that of 1242 KGOE in China, 1114 KGOE for Brazil, 3906 KGOE for UK, 3990 for EMU and 7921 KGOE in the USA. Considering the huge size of population, the use of energy per capita in India is found to be moderate and its pace in also comparatively slower.

This could partly due to unsatisfied demand arising due to domestic capacity constraints. A large section of India’s population is still not in a position to buy and use any commercial sources of energy due to their poor economic capacity. Major portion of these energy resources are being used by a small section of rich and middle class people of the country.

Thus economic empowerment of this large section of poor people will lead to a huge demand for energy in near future leading to a serious energy crisis in our country. There is also enough evidence of wastage in use of scarce energy resources by the richer and middle class people of the country.

Sudden spurt in the use of private vehicles by these sections of population and the faulty vehicle policy pursued by the Government may lead to a serious energy crisis in near future in the context of shrinking national as well as global reserve of energy.

There is considerable room to improve energy efficiency, especially of motor vehicles and in the generation, transmission and end-use of electricity, commercially viable and economic attractive technology options in use in the developed world, should be considered and adopted.

Finally, wastage in the use of energy, especially in respect of petroleum and electricity needs to be immediately controlled both by pursuing the policy of imposition and awareness for attaining curtailment in consumption in the use of energy resources.

Thus under the present scenario of energy crisis, improving energy efficiency and demand side management measures like encouraging urban mass transport are quite important. Sustaining economic growth is critically dependant on significant supply augmentation and change in the composition of energy use.

Import dependence, for meeting the primary energy demand in the country, has been increasing over a long period since 1990-91 to 2006-07. In order to reduce incremental import dependence of country’s energy requirement in the medium term to long term entails a number of measures.

These include:

(a) Tapping India’s coal reserve with appropriate technology and reforms in the coal sector to increase competition

(b) Mitigating transportation constraints on availability of coal;

(c) Accelerating exploration of oil and gas within the country;

(d) Fully exploiting the nuclear and hydro-potential for power generation; and

(e) Expediting programmes for energy generation through renewable and non-conventional sources. Besides, a steps up of domestic production, the remaining deficit would have to be bridged by entering into strategic geo-political alliances to access the energy assets in the region. There is also a need for regulatory reform to implement open access in power sector to facilitate competition.

Finally, putting a curb on wasteful use of energy, especially in respect of petroleum and electricity is the urgent need of the hour. This needs to be attained by pursuing a rational policy of imposition and awareness for attaining the required curtailment in consumption in use of energy resources and also for pursuing a policy for conservation of energy in real and rational manner.

• Energy literacy is crucial for an equitable energy transition and essential as individuals are impacted by the energy transition in myriad ways.
• This means ensuring people understand the complexity behind these transformations, including their scope and scale, and the impact of different facets of the energy transition.
• The Centre for the Fourth Industrial Revolution in Malaysia and the World Economic Forum’s Centre for Energy and Materials are piloting a programme that supports the country’s young people and research communities in unpacking the complexities of the energy triangle.

The world is at a critical inflection point where societies and industries are rapidly transforming. Changing our energy systems to be cleaner while meeting energy needs worldwide and ensuring stable and secure futures requires large-scale transformations in industry and society.

Governments, business leaders and civil society organizations are all grappling with how to transform systems. However, those who are both crucial to and affected by these changes must understand the transformation and how it affects them. They cannot be left behind.

Have you read?

Can we become ‘energy literate’, the evolving dynamics of asia-middle east relations during the energy transition, 5 key insights into how to accelerate an equitable energy transition, why energy literacy is important.

Energy literacy is key to broadening understanding of the complexities behind energy systems. From individual consumption habits to acceptance of new energy infrastructure to job creation, energy systems affect the public's day-to-day activities. It is crucial to increase public awareness of the energy system's multifaceted nature to build a future energy system for all.

Investing in energy transition promises lasting socioeconomic gains. Individuals are key in realizing a rapid, equitable and inclusive energy transition.

Wider public support must be sought to support an equitable and inclusive energy transition and prepare individuals for its implications on society, the economy, and culture. This means ensuring people understand the complexity behind these transformations, including their scope and scale, and the impact of different facets of the energy transition.

That would help ensure its inclusivity and society’s readiness for it.

While energy equity and inclusivity are essential to building a robust, resilient, and fit energy system in time for the 2030 goals, stakeholders at different levels – individuals, communities, businesses, and governments – must be engaged as the energy transition will play out at these different levels.

How can it be scaled?

It has become increasingly clear that firmly integrating equity and inclusivity into the business and economic case is essential to driving business opportunity. However, economic development and wider public support for the energy transition must happen in tandem for quick progression, requiring action across multiple areas of the energy system to set the pace for reaching key milestones in 2030 and 2050.

The shift towards a future energy system will be a multidimensional process that differs by market and country. Everyone will drive it and must play their part: consumers, financiers, innovators, producers and policymakers. ​

Some of the approaches needed to achieve a secure, equitable and sustainable energy system by 2050 include:

• Transforming energy demand and doubling energy efficiency.
• Enabling the rapid and responsible deployment of clean energy supply and delivery infrastructure.
• Strengthening the economic and business case for the transition.
• Driving industrial transformation that unlocks system value.
• Scaling up and deploying technologies and innovation.

Fostering an equitable energy transition is also key to scaling up and increasing general energy literacy is a core component.

Who is moving to bridge energy literacy

The Centre for the Fourth Industrial Revolution (C4IR) in Malaysia is taking on the challenge of improving energy literacy by supporting the country’s young people and research communities in unpacking the complexities of the energy triangle. C4IR Malaysia and the World Economic Forum's Centre for Energy and Materials are piloting an energy literacy programme to increase public awareness and understanding of the energy transition.

Malaysia ranked 35th among 120 countries on its energy system performance under the Energy Transition Index 2023 . The Energy Transition Index provides data and insights on the energy and industry transition to guide transition efforts. It seeks to raise awareness around the gaps and opportunities for transitioning energy and industrial systems.

At the same time, Malaysia has committed to achieving 70% of energy coming from renewable resources by 2050, with strategies and plans highlighted under the National Energy Transition Roadmap (NETR). As a country that has traditionally been a strong regional trader in fossil fuels, this is a significant commitment that must involve all segments of society. Because of this, energy transition literacy is made much more important.

The energy literacy programme will uncover the different analyses that went into the ranking and engage the public on what is needed to advance energy equity, sustainability and security within the energy transition to enable positive economic and social development.

The pilot programme will be amplified through the Centre for Energy and Material ’s global work to expand this approach and curriculum to different audiences worldwide.

Understanding Coal’s Classification as Renewable or Nonrenewable

This essay about coal discusses its classification as a nonrenewable resource. It explains that coal is formed from plant remains over millions of years, making it impossible to replenish on a human timescale. The essay highlights the finite nature of coal reserves and the environmental impacts of coal combustion, such as greenhouse gas emissions and pollution. It contrasts coal with renewable energy sources like wind and solar, which are naturally replenished and have a lower environmental impact. The essay also touches on the global reliance on coal and the need to transition to sustainable energy sources for long-term energy security and environmental health.

How it works

The categorization of coal as either a renewable or nonrenewable resource stands as a pivotal subject within dialogues concerning the sustainability of energy and its environmental ramifications. To grasp the rationale behind considering coal nonrenewable, one must delve into its genesis, its availability, and the implications it bears for long-term energy strategies.

Coal, being a fossil fuel engendered from the remnants of vegetation that thrived and perished millions of years ago during the Carboniferous epoch, undergoes a transformative metamorphosis over extensive geological epochs.

Entombed beneath layers of sediment, these botanical remnants are subjected to formidable levels of heat and pressure, undergoing a metamorphosis that spans millions of years, rendering coal irreplaceable within the temporal scope of human existence. Upon extraction and utilization, coal is irrevocably depleted. This stands in stark contrast to renewable resources like solar or wind energy, which undergo natural replenishment over brief intervals.

The finite nature of coal reserves further accentuates its nonrenewable designation. Geological assessments indicate a substantial, albeit finite, global reservoir of coal. Projections suggest that if contemporary consumption rates persist, coal reserves may face depletion within the forthcoming century. This finite availability poses formidable challenges for energy planning, necessitating a shift towards more sustainable energy sources. With the exhaustion of the most accessible coal deposits, the remaining reserves will prove increasingly arduous and economically burdensome to extract, thereby exacerbating environmental and economic repercussions.

The combustion of coal for energy begets profound environmental consequences, thereby augmenting its classification as a nonrenewable resource. Coal combustion releases substantial quantities of carbon dioxide, a prominent greenhouse gas that propels climate change. Additionally, mining and combustion yield pollutants such as sulfur dioxide, nitrogen oxides, and mercury, which pose deleterious effects on air quality and public health. These environmental detriments persist not merely in the immediate term but endure over protracted durations, impacting ecosystems and communities across successive generations.

In contrast, renewable energy sources such as wind, solar, and hydroelectric power offer a sustainable alternative. These resources undergo natural replenishment and exert significantly lesser environmental footprints. Transitioning to renewable energy is indispensable for mitigating climate change and diminishing reliance on finite resources like coal. Advancements in technology and energy storage are rendering renewables increasingly feasible and cost-effective, thereby diminishing the imperative for coal.

Despite these realities, coal retains a prominent position within the global energy amalgam, particularly within developing nations, where it is perceived as an affordable and dependable energy reservoir. This reliance engenders a multifaceted challenge: striking a balance between immediate energy requisites and the long-term imperative of sustainability. Policymakers must tread cautiously, ensuring energy security while concurrently advocating for cleaner alternatives.

Investment in cleaner coal technologies, such as carbon capture and storage (CCS), can partially assuage environmental impacts. However, these technologies remain costly and are not yet widely implemented. While they may offer interim relief, they fail to address the fundamental issue of coal’s nonrenewable nature. Ultimately, focus should center on diminishing coal dependency and hastening the adoption of renewable energy sources.

In summary, coal unequivocally qualifies as a nonrenewable resource due to its formation process, finite reserves, and substantial environmental repercussions. While pivotal in propelling industrial progress, the trajectory of energy must veer towards sustainability. Renewable energy sources chart a viable path forward, heralding a cleaner, more sustainable energy vista. Transitioning away from coal and other fossil fuels stands not solely as an environmental necessity but also as an economic and social imperative for safeguarding long-term energy security and environmental well-being.

Short essay on the Energy Resources of India

Energy is the capacity to work. We use energy at various levels in different forms. It is used in the kitchen for cooking food to run machines at the factories. The motor vehicles, the trains, the turbines and the aero planes are driven by the energy. The exploration of Antarctica or the arrival of man on the moon is only possible by harnessing energy rich fuels.

Energy provides the power to progress. Its uses at present life are manifold. We cannot grow without it. More the man is advancing towards modernity, more he is becoming dependent on energy. From the prehistoric period, when man first came to know about the use of fire, till date, it plays a key role in the economic and social developments of mankind.

A nation is considered rich not by amount of minerals or industrial resources it possesses, but by its technical ability it has acquired and scientific progress it is making, which depends ultimately on the supply and consumption of energy. The per capita daily consumption of energy of the developed countries is much higher in comparison to the developing countries like India.

ADVERTISEMENTS:

Energy consumption pattern of selected nations

We have 15 per cent of world’s population; but we consume only 2 per cent of the world’s total energy. Whereas countries like USA, Canada, UK, Japan etc. have very less population but their energy consumption is much higher. That is the main reason for which these countries are categorized under ‘developed’ and India under ‘developing’ countries. The common units for expression of energy are calorie and BTU or British thermal unit when the quantity is large; we express it in Mega Watt (MW).

Energy Resources:

Along with all other natural resources like air, water, land, forestry and fisheries, energy also occupies an important place. Our progress And prosperity depend solely upon it. Natural resources, energy and Environment are intimate related. Distributed or any one would definitely cause disturbances in other two.

Energy is required for beneficial use of natural resources and the resources, on the other hand, provide energy. The interaction of these two in the environment in safe and tolerable limit is called ‘limit of tolerance*. When this is disturbed, great disasters occur.

Depending on the source and availability, energy resources are mainly of two types.

(i) Non-conventional or renewable energy.

(ii) Conventional or non-renewable energy.

(i) Non-conventional or renewable energy

It is a type of non-replenish able or non-exhaustible form obtained from the continuous or repetitive currents of energy occurring in the natural environment. As the source of energy is unlimited, it is also called infinite or renewable energy.

The examples are: Biomass and Biogas Solar, Wind, Tidal, Minihydel and Geothermal.

(ii) Conventional energy

All the non-renewable types of energy come under this category. In this case, the raw materials that provide energy can not be replaced. Once it is used, its stock is depleted for ever. The common types are coal, Oil Natural gas and recently the Nuclear energy.
