State that energy may be stored as kinetic, gravitational potential, chemical, elastic (strain), nuclear, electrostatic and internal (thermal)

Describe how useful energy may be obtained, or electrical power generated, from: (a) chemical energy stored in fossil fuels (b) chemical energy stored in biofuels (c) hydroelectric resources (d) solar radiation (e) nuclear fuel (f) geothermal resources (g) wind (h) tides (i) waves in the sea including references to a boiler, turbine and generator where they are used

Recall and use the equation energy = current × voltage × time, E = IVt
