Biofuels are a Green Energy Source

Biofuels are also a green energy source. It has been around for a very long time and lately, people are beginning to take notice.

Liquid biofuel which is the one used in cars is a natural and renewable domestic fuel that can only be used for diesel engines. This can be made from vegetable oils mostly soy and corn. The nice thing about it is that it contains no petroleum, is nontoxic and biodegradable.

By fueling up with biofuel, you decrease the pollutants in the air because it does not emit anything. Right now, it is the only fuel approved by the Environmental Protection Agency (EPA), passed every Heath-Effects Test of the Clean Air Act and meets the requirements of the California Air Resources Board (CARB).

Why is Hydropower a Green Energy Source?

It is estimated that we only use 3% of our damns to products hydroelectric power. The Oak Ridge National Laboratory (ORNL), with inputs from the Idaho National Laboratory (INL), executed the technical analysis and identified 54,000 NPDs (non-powered dams). It just doesn't make sense, with the price of oil and the pollution value of coal. Why aren't we utilizing this all ready made green energy source.

Hydropower is a green energy source because we are able to harness electrical power by converting water into electricity.

Geothermal as a Green Energy Source

We have the technology to do a lot of things and one of these is to tap the earth’s energy. This is exactly what we do when we decide to use geothermal which happens to be a
green energy source.

Geothermal energy is energy obtained by tapping heat from the earth itself. This comes from magma and the radioactive decay of uranium, thorium, and potassium.

The downside to geothermal energy is the fact that it is expensive to build. On the other hand, because the earth's crust continuously decays replenishing the heat, it is still a renewable source of energy.
