Biofuels are combustible fuels created from biomass.

“Firewood is the oldest bio-fuel mankind has used, now we have biogas, gasohol and many more. Carbon dioxide is produced when these burn, but as long as the trees and plants are allowed to re-grow, burning them simply helps carbon on its way round its natural cycle.

There are many such digesters in use all round the world, where the gas is used for cooking and lighting and the remains are a rich fertiliser. Biogas digesters are used in most sewage works where the methane is burnt to generate electricity.

“While many of us are already familiar with electric cars, there are numerous other energy options for motorists who may prefer to deviate from gasoline. Hydrogen, biofuels, ethanol, propane and solar power are just some of the alternative on offer for the ‘greener’ motorist. Be aware, though, that each of these options has their downsides, and refuelling stations for alternative fuels are still in very short supply, although this is likely to change over the next few years.”
