Current Sources Of Renewable Energy

By Virginia Harrison

Have you heard about alternative energy? Chances are you have. More and more businesses are going ‘green’ and more new businesses are starting for the purposes of developing alternative fuels. We’re already using some sources of alternative energy like solar, wind and hydropower. There are other sources also but these need to be further developed before they are practical for wide range use.

There are two main positives to renewable energies. First, of course, is the fact that this energy is far better for the planet. But what many people don’t realize is that they are also more cost effective. In some instances, the technologies that are used to gather the energy are still too expensive to make the energy widely available. In time this will change.

If you hear ‘alternative fuels’ and you think that this is far in the future, think again. We’re already well on our way to becoming a ‘green’ world energy-wise. We use alternative fuels in many ways all over the world.

In fact, nearly 20% of the world’s energy supply is from renewable sources. This number is only going to rise, since oil is an unsustainable energy source.

Right now across Europe you can find numerous solar plants and wind farms. These efficiently harness natural resources that are essentially inexhaustible. Over the next ten years, expect to see more and more such energy projects.

Ethanol is a very popular alternative energy source around the world. It’s produced from corn. Brazil makes widespread use of ethanol, they use it for around 18% of their total fuel usage.

This is because in most other countries, cars run on a mixture of gasoline and ethanol. Generally you can get a mix of up to 10% ethanol, but the majority still has to be gasoline. There are critics of ethanol, though, who argue that this is not an appropriate fuel source. Corn can be used as food for people of course, and these critics argue that food crops should not be used for fuel.

If you are interested in biofuels, in fact, corn is not the only possibility. There are others that are so common that no corn would have to be diverted for fuel.
