Energy resources — Supplement Learning Objectives

Summary
  • Know that radiation from the Sun is the main source of energy for all our energy resources except geothermal, nuclear and tidal
  • Know that energy is released by nuclear fusion in the Sun
  • Know that research is being carried out to investigate how energy released by nuclear fusion can be used to produce electrical energy on a large scale
  • Define efficiency as: (a) (%) efficiency = (useful energy output)/(total energy input) (x 100%) (b) (%) efficiency = (useful power output)/(total power input) (x 100%) recall and use these equations
