A power plant is a facility that generates electricity. It may serve a community or a particular commercial business. Power plants generate electricity through a variety of methods including burning coal, oil, gas or other fuels, or through hydroelectric generators powered by running water, nuclear reactors, or even tidal energy in coastal areas. Still, most power plants rely on large generators that burn fossil fuels.
A fuel-burning plant generates large amounts of waste such as smoke and ash, and requires appropriate design and safety features to protect the surrounding communities and the environment. In recent years, the environmental impact of burning fossil fuels has led to increasing interest in renewable-energy power sources such as wind farms and solar power to replace traditional power plants.
