Understanding bioenergy and climate change mitigation requires knowledge of several disciplines, from thermodynamics in the study of power generation to biochemistry and policy in the case of biofuels and energy trade. The first three parts of this book provide the scientific and technical background for the production and use of bioenergy. They consider the chemistry, biochemistry and physics of the production and use of solid, liquid and gaseous biofuels. The fourth part describes the political forces that drive and deter renewable energy production on the global scale, and demonstrates how global politics and economics combine with climate change policy to produce the energy transition. The book will be invaluable for graduate researchers, academics and climate change scientists, and decision-makers in the energy industry. Part of IOP Series in Renewable and Sustainable Power.
