This book discusses the generation of green energy, providing fundamental scientific information on the availability of sustainable biological resources. It addresses inter- and multidisciplinary topics, including policies and strategies for sustainable energy; the environment and advanced renewable energy technology; electricity generation through solid waste management; and direct electricity generation using microbial fuel cells. It examines the application of the principles and quantitative relationships that define the process as an effective technique to teach applied aspects of biomass energy technology conversion. In addition, it describes the latest commercialisation of microbial fuel cell technologies, bio-diesel production from microalgae, fermentation technology based on biobutanol from bacteria, and direct ethanol production from microalgae with attractive illustrations and models developed by corporate sectors.
