Biofuels

Biofuels are any kind of fuel made from living things, or from the waste they produce. This is a very long and diverse list, including: wood, wood chippings and straw, pellets or liquids made from wood, biogas (methane) from animals' excrement and ethanol, diesel or other liquid fuels made from processing plant material or waste oil. But can biofuels deliver on their promise as a sustainable and environmentally friendly source of energy? This book looks at the variety of fuels available, including second generation biofuels, and assesses their prospects.
