A power station (or power plant) is a place where electricity is produced. Most do this by electromagnetism, spinning a coil of wire past a magnet to induce an electric current. Usually the spinning is powered by a steam engine, specifically a steam turbine. The steam may be created by:
- Burning fossil fuels to boil water
- Nuclear power, using radioactive sources
- Using the earth's heat, called geothermal energy, to boil water
- Using the sun's heat
Some do not use steam engines to spin the generator. Rather they use:
- Hydropower, which uses the power of moving water to drive turbines
- Using the wind to drive wind turbines
- Internal combustion engine power
A few power stations use the sun's rays to generate solar power without motion. There are many power stations around the world, because many things need electricity to work.
Renewable energy resources
- Renewable heat energy
- Renewable flow energy
Non-renewable energy resources
These all use heat as a source of energy.
Solid-state electricity sources
These sources have no moving parts. They are more expensive than generators, and are used where other questions are more important.
