Explores the production of biofuels as alternatives to fossil fuels, focusing on the technological issues that need to be addressed for any new fuel source. Each type of biofuel currently in production is considered in detail, covering the benefits and problems with production and use and the potential for biological material to provide sufficient energy for the world's population - the principles on which future fuel development are based.
1. Energy and fossil fuel use; 2. Consequences of burning fossil fuels; 3. Mitigation of global warming; 4. Biological solid fuels; 5. Gaseous biofuels; 6. Liquid biofuels to replace petrol; 7. Liquid biofuels to replace diesel; 8. Benefits and deficiencies of biofuels.
