This 2-volume set provides an overview of the global progress in achieving renewable energy goals through sustainable and economically viable means. Volume II covers various potential renewable energy sources such as solar, wind, hydro and biomass, including the technologies associated with each that are economically feasible while still being environmentally sustainable in their implementation. This then leads into a discussion of how a transition to a green economy based on renewable energy could be achieved, including global opportunities, trends, policy considerations and societal implications. The book will appeal to academics, industry professionals and policy makers engaged with the energy economy, renewable energy research and environmental sustainability.
