1 Survey of renewable energy

Abstract

The chapter is a survey on renewable energy. Before industrialization, renewable energy had been the only source of energy available. At present, renewable energy can be used to provide only a rather limited amount of secondary energy. Actually, renewable energy available in total worldwide could satisfy the total worldwide demand on primary energy. Annual potential of renewable energy in units of exajoule is tabulated. Renewable energy now contributes only a small fraction to satisfy the total demand on “technical” energy (not including “natural” energy in form of primary biomass to be finally converted to food), mainly using hydro power to generate electricity and burning biomass, especially leftovers and waste, to produce heat and electricity. The availability of electric power from different energy sources, its restrictions and fluctuations in time are graphically illustrated. The chapter also presents a survey of technologies to convert renewable energy into final energy demanded. Illustrations also include possible utilization of the different kinds of renewable energy, such as hydro power to produce electricity, wind energy, sunlight, biomass, heat from earth interior, water, soil and air. The main obstacles to increase the use of renewable energy, synergy effects of extensive use of renewable energy are also discussed.
