註釋Covers energy crops that are already in use and those that are being developed or researched. The introductory chapter defines energy crops before reviewing the development and current state of the technology. It also gives an historical perspective and introduces the ethical issues. Each of the subsequent chapters is dedicated to a single crop and describes the current usage of that crop for energy, its potential for future development, the economics of its use for energy production, and the research that is being undertaken to tailor it for use as an energy crop. Where appropriate, the implications for food and feed security are balanced against the benefits in terms of fuel security, the impending oil supply 'peak', the need to reduce CO2 emissions, and the implications for climate change mitigation. The chapters by representatives of the plant breeding and biofuel industries give an industrial perspective on why energy crops have 'come of age'. They also describe how the sector is expected to develop with a wish list of crop improvements that industry would like to see realized. These include higher levels of fermentable starch, cellulose, fibres and oil quality through to the production of pure hydrocarbons.
