Renewable Fuels

Renewable fuels are fuels that are created as fast as they are consumed.

There are two main systems for creating such fuels, the first involves a biological process to convert sunlight into biomass, which is then converted into the actual fuel. These fuels will generally be used in much the same way as fossil fuels. An example of such a fuel is Bio Diesel, a diesel oil that is created from biomass.

Another option is to use energy to effect a chemical reaction (such as the separation of water into hydrogen and oxygen) which will then later be reversed to liberate the energy again.
