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 classification. 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 beyond doubt 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 unfilled 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 contemporary worldwide capacity being about 100 GW.

Clean Energy

“Clean energy” is simply any form of energy which is made 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. But there are also other forms of geothermal energy which are harmless and clean.

Clean energy makes the less impact on the environment than our contemporary conventional energy sources do. It makes 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 vital 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 reasonably priced.

Carbon emissions and other forms of pollution are not only made by heavy manufacturing factories. They are made in the ordinary household as well. Energy efficiency has become an vital aspect of our lives.

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