This book examines the various types of biofuels and the most current cellulose ethanol production technology that focuses on cost-effective biomass conversion, along with relevant economic, environmental and policy considerations. It offers a review of biofuels production as an attractive alternative to fossil fuels (crude oil, natural gas and coal) production, with due consideration for benefits ranging from reduced greenhouse gas emissions to reduced dependency on imported oil. It is the author's hope that readers would find this book informative and practical enough to recommend it to others.
