Renewable Energy Resources

This chapter discusses the primary roles of solar, geothermal, wind, hydro, ocean and biomass energies in combating environmental challenges. The energy sources are treated particularly in the forms of thermal and electrical. The chapter also covers the fundamental aspects, technological dimensions, operational details, examples and practical applications of renewable energy systems. The performances of such systems are evaluated through energy and exergy approaches. The renewable energy systems are also evaluated from various technical, environmental and sustainability perspectives. Furthermore, a case study is presented for an integrated multigenerational energy system to specifically study its design, operational conditions and performance criteria.
