Considering each technology in depth from both scientific and environmental perspectives, the book covers solar energy, photovoltaic, wind, wave, tidal and hydro power, biofuels, geothermals and more, and also features a new chapter on institutional factors, including ergonomics. In addition, extra worked problems and case studies are provided to help readers put theory into practice. After each chapter, reading and web-based material is indicated for further study, making this text ideal not only for practitioners but also for students on multi-disciplinary masters degrees in science and engineering as well specialist modules in science and engineering first degrees.
