What are fossil fuels?

Essentially there are three fossil fuel sources available to the world but each of them are dwindling. The most abundant is coal; coal is widely used and inexpensively extracted. As such, we have come to rely exceptionally heavily on coal and while there is still quite a large amount of coal left it is estimated that America’s remaining coal will sustain the country for the next 200 too 300 years but it is by no means a perfectly clean form of power.

The biggest problem is that coal is made up of carbon, like living beings, and the burning it needs to go through in the production of energy forms carbon dioxide. This carbon dioxides traps the earth’s heat and is a major contributing factor that scientists believe to be causing global warming. On a more positive note, though, scientists have created a more effective method to burn coal that traps 99% of the impurities and harmful gases that are emitted.

Apart from coal we heavily rely on natural gas and oil that are also in limited supply, and this is where the problem lies. The human race is consuming more and more energy with every day that passes and our resources of fossil fuels are being seriously depleted thanks to the way we live. The answer to this problem seems to lie in alternative energy.

What is alternative energy?

Alternative energy are non fossil fuels and do not deplete the earth’s resources of fossil fuels any further. Countries across the world are being pushed into investing money into the research and production of alternative energy and many countries already have natural energy sources producing usable energy.

Wind energy.

One of the first used forms of alternative was wind energy. Many countries have developed wind farms, both off shore and mainland wind farms. Turbines are turned by wind, creating a viable renewable energy source. The problem with wind energy is that turbines can’t be located near housing districts because of the noise they create, although with further research and investment technologies associated with wind energy and wind turbines will undoubtedly keep improving.

Solar Energy.

In many countries grants are now available to help pay for photovoltaic tiles which collect the heat from the sun’s rays and convert it into an exceptionally safe and renewable form of alternative energy. Whether used to create electricity or to simply heat water or a central heating system, solar energy is easily obtained and the technology is very affordable. With solar energy consumers are assist with the protection of the environment.

Biomass.

Biomass is still a relatively unused form of energy in many parts of the world but more and more money is being put into funding of biomass. Biomass is the creation of energy using plant materials, and is another source of clean, renewable energy. America is one country that uses Biomass to quite big effect, being the largest source of renewable energy every year since the year 2000.

These are only a few alternative energy sources that are available around the world, and more and more funding is becoming available for the production and research of these sources.

To many people, the differences between “alternative energy,” “renewable energy,” and “clean energy,” might not be obvious. But each term is unique and has its own individual definition. These three terms are not all exactly the same.

Alternative Energy

When we speak of alternative energy, we refer to sources of usable energy that can replace conventional energy sources (usually, without undesirable side effects). The term “alternative energy” is typically used to refer to sources of energy other than nuclear energy or fossil fuels.

Throughout the course of history, “alternative energy” has referred to different things. There was a time when nuclear energy was considered an alternative to conventional energy, and was therefore called “alternative energy.” But times have changed.

These days, a form of “alternative energy” might also be renewable energy, or clean energy, or both. The terms are often interchangeable, but definitely not the same.

Renewable Energy

Renewable energy is any type of energy which comes from renewable natural resources, such as wind, rain, sunlight, geothermal heat, and tides. It is referred to as “renewable” because it doesn’t run out. You can always get more of it.

People have begun to turn to this type of energy due to the rising oil prices, and the prospect that we might one day deplete available sources of fossil fuels, as well as due to concerns about the adverse effects that our conventional energy sources have on the environment.

Of all the different types of renewable energy, wind power is one which is growing in its use. The number of users who have some form of wind power installed has increased, with the current worldwide capacity being about 100 GW.

Clean Energy

“Clean energy” is simply any form of energy which is created with clean, harmless, and non-polluting methods.

Most renewable energy sources are also clean energy sources. But not all.

One such example is geothermal power. It may be a renewable energy source, but some geothermal energy processes can be harmful to the environment. Therefore, this is not always a clean energy. However there are also other forms of geothermal energy which are harmless and clean.

Clean energy makes the less impact on the environment than our current conventional energy sources do. It creates an insignificant amount of carbon dioxide, and its use can reduce the speed of global warming – or global pollution.

As you can see, alternative energy, renewable energy, and clean energy are very similar. But it is important to know that there are differences.

There are many actions which can be taken, to help reduce the greenhouse gases in our atmosphere. Some of these steps can be taken in your own home. Many clean energy solutions can can be easily installed, and some kits are quite affordable.

Carbon emissions and other forms of pollution are not only created by heavy industrial factories. They are created in the common household as well. Energy efficiency has become an important aspect of our lives.

It’s important to start making changes now; if we want to save our planet for our children, for the flora and fauna of the Earth, and for the future of mankind. Clean energy, to be exact, can make a big difference.
