Read the paper to learn about the challenges, limitations, and benefits of implementing alternative energy sources. A particular part is dedicated to the importance of government policies in promoting the development and use of alternative energy sources. Overall, the essay on alternative sources of energy presents a comprehensive overview of the current state of renewable energy and its potential for shaping our future.

Introduction

Solar power, course of action, works cited.

The world has been overly relying on oil as a source of energy to fuel most of its operations. It is important to note that as much as 80% of the world’s energy comes from fossil fuel. Unfortunately, the fossil deposits we have in the world cannot last forever. They will be depleted one day and cause a lot of problems in the world.

Therefore, efforts should be made to ensure that other sources of energy are found so that when fossil fuel gets depleted the world does not come to a halt. In this regard, many people especially in the U.S. have been concerned with the steps that the government is taking towards encouraging development of other sources of energy.

Consequently, the government has been urged to reduce restrictions impeding the development of renewable sources of energy and increase funding of the same. However, to address this issue, it is better to understand some of the sources renewable energy.

Among the proposed sources of power to be used is solar energy. Solar energy is a renewable source of energy because the sun has been there and can only be absent for a very short period of time. On the same note, harnessing of solar energy is noise proof which means that noise pollution is avoided when using solar power (Boxwell 58).

Similarly, solar power is environmental friendly because it does not produce any form of pollution. In addition, equipments used in the production of solar power are cheap to maintain thus the long run cost of production is low. Moreover, it is easy and cheap to install appliances of solar power.

Similarly, the electricity produced from solar energy can be used to power virtually every thing that uses power (Boxwell 59). It is also important to note that the production of solar power does not lead to environmental degradation like digging up the ground or deforestation.

However, solar power has its disadvantages. To begin with, some people have argued that the initial cost of installing solar power harnessing equipment is very high. Additionally, harnessing of solar power is affected by whether and cannot be done during cloudy or rainy days and at night. Therefore, another source of energy is needed to act as a back up (Boxwell 60).

On the other hand, wind energy is also another source of energy that can replace fossil fuel. Wind energy does not emit green house gases which are dangerous to the environment. Furthermore, no fossil fuels are burnt to produce wind energy thus it does not pollute the environment (Miller and Scott 407). Besides, extraction of wind energy is more efficient given the advancement in technology.

The turbines used to produce wind power only occupy little space at the base leaving room for other activities to be done on the ground. Moreover, wind energy is highly applicable in under developed parts of a country and can add to the tax base of the area.

In addition, renewable sources of energy, wind being among them, require minimal subsidies to maintain. On the same note, the cost of producing wind power is constant and therefore prices for wind power do not fluctuate. Most importantly, wind is free and thus cost of producing wind power is low in the long run (Miller and Scott 407).

It is crucial, however, to highlight that wind power has its share of disadvantages. Firstly, wind power depends on the flow of wind. On the days when the weather is calm wind power might not be generated. On the same note, the initial cost of producing wind power is quite high and individuals may not afford it (Miller and Scott 408). Lastly, power produced by the turbines is insufficient compared to power produced by fossil fuels.

Despite the disadvantages of wind and solar power, their advantages are definitely more. They are renewable and therefore they will never get depleted. Sooner or later the government will have to find alternative ways of producing power.

Consequently, it is high time that the government increased its financial support in the production of the two types of power (Miller and Scott 407). Reduction of restrictions is necessary but it might not be sufficient given the heavy initial cost. Similarly, renewable sources of energy, especially wind and solar power, are both economically and environmentally viable in the long run hence the need to invest in them.

The fact that the country currently satisfies most of its energy requirements should not blind our eyes. We will need to think of how we will operate in future. The fossil fuel that forms the giant part of energy source will definitely be exhausted with time.

It will be a great disservice to the future generations if we do not find sustainable energy sources. Consequently, the government has no option but to encourage the production wind and solar energy.

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.

Out with the Old, In with the Re(new)able

The United States has been operating as a country using limited fossil fuels, but what happens when it all runs out? Would it not be more beneficial to never find out? Renewable energy, energy that is not depleted after its use, is limitless and more sustainable than any other source in energy history. To initiate the clean energy movement is expensive, but there are countless benefits ranging from individual to global impacts in going completely renewable. The first recorded use of renewable energy was harnessing wind power to drive ships over water about 7000 years ago (Darling). However, renewable energy has been around as long as Earth has existed: wind, sun, geothermal, biomass and many more. Clean energy sources can be harnessed to produce electricity, process heat, fuel and other chemicals with significantly less impact on the environment. In 2014, renewable energy sources accounted for fourteen percent of America’s total electricity use (“Renewable Energy Sources”), a four percent incline from the prior year. Completely diverting from fossil fuels to renewable energy clearly is not a new concept for a select few of innovative countries. A few countries, for example, are Costa Rica, Norway and Iceland, all of whom have ran on renewable energy for the entire 2015 calendar year, diving deep into their own land’s resources and utilizing volcanic presence to produce energy (Rosecrance & Thompson 7). Following in the footsteps of Costa Rica and a few other third world countries, major economic powerhouses and biggest users of fossil fuels like the United States should convert to clean energy as a way to benefit the economy, environment and overall health of the country.

As a consumer, one is worried about how abandoning a safe form of energy and transitioning to something new can help or hurt their wallet. Not only can renewable energy help save money, it can also help make money. A 150 billion dollar investment into this new industry would result in 1.7 million job opportunities, reducing the unemployment rate in America by an entire percentage (Pollin & Heintz). The reason for the potential high employment rate is because the industry is labor intensive in the means of installation and maintenance, requiring a lot of manpower for ultimate success. However, the more we wait the more future benefits we are currently losing. In an American Solar Energy Association (ASES) report in 2009, they stated “the 2008 predictions for renewable energy industry in 2030 are significantly lower than the 2007 predictions (National Research Council 169).” Unlike fossil fuels, which are subject to volatile pricing fluctuating over time depending on the market, renewable energy is relatively “free” after installation, using natural resources. The process of transportation and maintenance is minimized allowing prices to stay constant throughout the years. The only way price can head is down; for instance, clean energy is more affordable than 25 years ago. In particular, wind energy, the fastest growing source of power, prices have declined from forty cents per kilowatt per hour to less than five cents per kilowatt per hour (“The Energy Story”), a remarkable change and a huge upside in favor of the conversion. As time continues, technology should continue its progression resulting in cheaper mediums to acquire the energy. Despite of this, the conversion should take place now so results are maximized for the future. All in all, clean energy can both save Americans money while help them make money, the perfect win-win for producers and consumers alike.

Abstaining from burning countless, yet limited fossil fuels every day and polluting the environment is the single biggest benefactor for moving towards a cleaner approach. Not only would greenhouse gas emissions, as well as other pollutants that cause smog and acid rain, reach minimal levels, but also the country is consequently assisting in the reduction of the global warming speed and effects. Unlike fossil fuels, which are unable to be replenished easily, renewable energy is limitless, feeding from natural resources. With the global and national population expected to continue rising, the demand for energy will follow. There is a multitude of different approaches to acquire renewable energy including the most used types: solar and wind power. Specifically, solar energy is the epitome of sustainability and efficiency, calculated through production and prices. Despite the massive amounts of energy used yearly nationwide, “the sunlight falling on the United States in one day contains more than twice the energy we consume in an entire year ( The Energy Story ).” As for wind power, “California [alone] has enough wind gusts to produce 11 percent of the world’s wind electricity ( The Energy Story).” Wind turbines take up a lot of space but still allow the area around it, usually farms, to be used regularly. In the United Kingdom, for comparison, the government set a target for renewable energy to make up 15 percent of their total energy expense by 2020. This motive results in a 34 percent cut in the country’s carbon emission in the same time span (National Research Council 180). Needless to say, renewable energy will make landmark strides in the progression towards a cleaner, better environment. The most important thing on this Earth is this Earth, and it’s society’s job to maintain it.

As well as helping the environment and wallets, renewable energy can help with everyone’s health. By cutting the emission of greenhouse gasses and fossil fuels, air pollution decreases. Air pollution, primarily those contributed through coal burning power plants emitting fine-particulate pollutants, is most associated with causing health problems, chiefly lung cancer. The Environment Protection Agency (EPA) predicts that conversion, or even standards, will prevent at least 100,000 heart attacks and asthma attacks per year. Additionally, EPA also estimates a projected 1,100 billion dollar income in health benefits due to avoiding illnesses and deaths (U.S. EPA). As a form of partnership, the health industry could invest a portion of this money into the clean air movement due to its beneficial health impacts and help make installation cheaper. A majority of these pollutants are associated with dangerous levels of climate change, this century’s biggest threat to human health. Climate change, a change in global climate patterns, “will increasingly jeopardize the fundamental requirements for health, including clean urban air, safe and sufficient drinking-water, a secure and nutritious food supply, and adequate shelter (World Health Organization).” Climate change is the main contributor and accelerator towards global warming. Global warming increases the risk of two deadly diseases: Plague and Ebola, to name a few. For Plague, changes in temperature and rainfall will affect rodent populations as well as the infected fleas they carry. Additionally, Ebola outbreaks tend to follow serious downpours or droughts, a likely result of climate change (Biello). The movement would not only lower the pollution rate and risk of infection, but also save countless lives across the globe during the process.

America, along with most other countries, needs to initiate their plans towards a more sustainable, cleaner form of energy. Renewable energy helps increase the production of the economy through the addition of million of jobs. Simultaneously, energy prices would be lower, also helping the consumer save money. However, it is vital to start now. The longer the wait, the less benefits are reaped. Likewise, the clean air movement will mark the beginning of recovery for the environment. Greenhouse gases and other emission will reach all time lows, possibly zero. This deduction is important to slow the rate of climate change and global warming. Stopping climate change and gas emissions in its tracks would also lead to more health benefits. There are dozens of deadly diseases and carriers that spawn from the irregular climate patterns. Also, climate change could affect physiological needs by lessening safe drinking water, food supply and shelter. The United States has a reputation of being an innovator, a leader for many countries. Why has it been so lackadaisical with something so important to everything in today’s society? It has a history of being scared of change; people are too comfortable with life as it is, but it could be better. With the United States recently moving in the right direction, it will be better.

• Alternative Sources of Energy

Introduction to the World of Energy

Sources of energy are very important and we perform different day-to-day tasks with the help of energy. Can you imagine your life without sources of energy? It will be very difficult to survive and life will end. But from where is this energy obtained? Are these sources man-made or natural? Have you ever heard about the alternative sources of energy that are used other than the traditional sources of energy? Let’s discuss these.

People started looking for other energy sources in the late 1900s so they could heat their homes, light their homes, and power their vehicles. People worried that sources like coal, oil, and nuclear power were depleting. Waterpower, wind power, and solar power are examples of alternative energy sources. These and other non-depletable energy sources are referred to as green or renewable.

What are Alternative Sources of Energy? 

Alternative sources of energy can be defined as the use of sources of energy other than the traditional fossil fuels (such as oil, coal, and natural gas), which are shorter in supply and which are considered harmful to the environment. It includes all renewable and nuclear energy sources. 

The most commonly used alternative sources of energy include the following:

Wind Energy

Solar Energy

Geothermal Energy

Hydroelectric Energy

Hydrogen Energy

Nuclear Energy

Tidal Energy

The above-listed sources of energy are explained below:

Uses of Alternative Sources of Energy

1. wind energy.

In this source of energy, the wind is used for producing electricity by making use of the kinetic energy created by air in motion.

2. Solar Energy

In this source of energy, the radiation from the Sun is used which is capable of producing heat, causing chemical reactions, and generating electricity.

3. Geothermal Energy

It is a source of energy that is taken from the Earth’s core. It comes from the heat which is generated during the original formation of the planet.

4. Bioenergy

In this source of energy electricity and gas are generated from the organic matter known as biomass. Bioenergy is one of the resources available to help meet the demand for energy, it includes electricity, heat and transportation fuel. 

5. Hydroelectric Energy

It is a source of energy that is obtained by falling water from high potential to low potential as potential is defined to flow down from a certain height. It is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity.

Importance of Alternative Sources of Energy

The importance of alternative sources of energy are discussed below:

Protects the Environment: Alternative sources of energy help to protect the environment and give it the opportunity to regenerate.

Helps in Providing Sustainable Fuel Systems: The alternative sources of energy can help in creating a sustainable fuel system and can help in sustaining the ecological balance of a region.

Helps in Reducing the Dependence on Imported Fuels: Another use of alternate sources of energy is that it helps to reduce the dependence on imported fuels.

Helps in Enhancing Income: It helps in enhancing the income of the country by creating additional employment opportunities for the population of the country.

Useful in Conserving Fossil Fuels: When we make use of alternate sources of energy it helps us in conserving fossil fuels.

Useful in Slowing and Reversing Climate Change: Because the alternate sources of energy have a much lower carbon content it helps to slow down and reverse climate change.

Useful in Economic Growth: Producing more utility-scale energy systems can help in creating more economic growth.

Thus it can conclude that the alternate sources of energy are the future energy sources that will help in sustaining the environment as well as help in minimising the dependency on conventional energy sources. These sources of energy need to be explored more and more.

FAQs on Alternative Sources of Energy

1. What percentage of the world uses alternate sources of energy and which is the most widely used alternate source of energy?

From 27% in 2019 the share of renewables in global electricity increased to 29% in 2020. The increase in alternative sources of energy mainly came at the cost of gas and coal, though these two sources still represent close to 60% of the global electricity supply. The most widely used alternate source of energy in the world is hydropower energy. Before lockdown, some measures were implemented, and shares of renewables were higher due to favourable weather conditions. The global use of alternate sources of energy was 1.5% higher in 2020 than in 2019.

2. Why are we looking at alternate sources of energy?

We are looking at alternative sources of energy because as our standards of living are increasing day by day so are our energy requirements. So a need has arisen to exploit and look for more and more alternative sources of energy. Another reason why we are looking for alternate sources of energy is that our conventional sources of energy like fossil fuels get depleted very soon which is why we need to look for other alternatives as well.

3. Write some interesting facts about alternative sources of energy.

Some interesting facts about alternative sources of energy are given below:

There are over two million solar power systems installed in the United States.

The alternate sources of energy create five times more employment opportunities than the conventional sources of energy.

Solar energy is nearly 200 years old.

One wind turbine can be used to power nearly 1500 homes for a year.

Essay 221 – The use of alternative sources of energy is being encouraged

Gt writing task 2 / essay sample # 221.

You should spend about 40 minutes on this task.

Write about the following topic:

Fossil fuels, such as coal, oil and natural gas, are used in many countries. However, the use of alternative sources of energy, including wind and solar power, is being encouraged.

Is this trend a positive or negative development?

Give reasons for your answer and include any relevant examples from your own knowledge or experience.

Write at least 250 words.

Model Answer 1:

Fossil fuels harm the environment and to save our planet we need to encourage the use of green energy. The use of alternative sources of energy, or ‘green’ energy, is a positive trend of development, and indeed their use should be encouraged further.

As the demand for energy worldwide is increasing the strains on the existing and already limited resources also increase. To solve this problem, we must consider two issues: how to better use the existing, limited fossil fuel resources and how we can encourage the use of alternative energy sources.

It is universally acknowledged that there is a limitation on the use of fossil fuels, especially coal and oil. Some countries are rich in oil deposits like OPEC, whereas China is rich in coal deposits and Russia in natural gas. Others, such as Japan and Germany, are completely dependent on the import of resources. For all countries- resource-rich versus resource-poor, alternative energy should be encouraged and utilised to reduce the dependence on fossil fuels as well as to keep the global environment in balance and ‘healthy’.

The only way is to turn to other sources to get energy supply. Wind power and solar power are at present feasible alternatives. France is one country that has the advanced technology needed to produce extremely efficient solar panels to store energy from the sun. Both kinds of power can reduce a country’s dependence on fossil fuels. Furthermore, they do not pollute the environment and in turn, help keep the ecosystem stable.

To conclude, while fossil fuel resources are diminishing, the energy demand continues to increase year after year. It is a positive trend to develop other alternative sources of power and the experiences should be shared and promoted. If this switch to alternative energy is encouraged early enough, then we may yet avoid the pending energy crisis and environmental disaster.
