Imagine powering your entire home or even your car or bike using left-over cooking oil or plant-based foods. It's not something from the hit movie Star Wars, the process is known as Biofuel.

Biofuels can come from any living thing, including the waste they produce.

The list can be very long; from wood and wood chippings to straw pellets or liquids made from wood biogas (methane) and from animals' excrement ethanol, diesel or other liquid fuels made from processing plant material or waste oil in recent years, according to a BBC News article.

But the term "biofuel" has come to mean the last category — ethanol and diesel, made from crops including corn, sugarcane and rapeseed.

Bermudian Robin Gray, an energy futurist, is one of a slim few on the Island who are licensed to process bio fuel. In the US Biofuel is better known as ethanol.

Bio-ethanol, an alcohol, is usually mixed with petrol, while biodiesel, another variation, is either used on its own or in a mixture.

Brazil leads the world in production and use, making about 16 billion litres per year of ethanol from its sugarcane industry.

Sixty percent of new cars in Europe can run on a fuel mix which includes 85 percent ethanol.

The European Union has a target for 2010 that 5.75 percent of transport fuels should come from biological sources, but the target is unlikely to be met, according to the BBC.
