This book provides technical data and information on unconventional- and inactive energy sources. After reviewing the current global energy situation, individual chapters discuss fossil fuel sources and renewable energy sources. It focuses on future energy systems and explores renewable energy scenarios including water energy and power, biofuels and algae energy. It also provides essential information on energy from inactive sources, energy from waste materials and the optimization of energy systems.

Professor Ayhan Demirbas´ area of work is mainly concerned with renewable and sustainable energy technologies. He has studied on the subjects of pyrolysis, liquefaction, gasification, and supercritical fluid extraction and gasification of biorenewable feedstocks. He has analysed the products from pyrolysis, liquefaction, gasification, and supercritical fluid extraction of biomass. Professor Demirbas has studied on the subjects of renewable transportation fuels such as biodiesel, biomethanol, bioethanol, biogas, biohydragen, gasoline and diesel fuel from fisher-trops synthesis of biofuels. He has also studied petroleum products, new products from crude oil, renewable energy resources, global renewable energy strategies and scenarios, sulfur removal from coal using alkali from biomass ashes, toxic emissions from firing and co-firing processes, global climate change, hazardous materials, persistent, organic pollutants, spectrophotometric determination of carbaryl pesticides in soil and drinking water and, creal analyses etc.
