In some power stations an energy source is used to heat water. The steam produced drives a turbine that is coupled to an electrical generator.
Energy sources include:
uranium and plutonium, when energy from nuclear fission is used to heat water
biofuels that can be burned to heat water.
Water and wind can be used to drive turbines directly.
Electricity can be produced directly from the Sunís radiation.
Small-scale production of electricity may be useful in some areas and for some uses, eg hydroelectricity in remote areas and solar cells for roadside signs.
Using different energy resources has different
effects on the environment. These effects include:
the production of waste materials
noise and visual pollution
the destruction of wildlife habitats.
