Most power stations contain one or more generators, a rotating machine that converts mechanical power into electrical power . The relative motion between a magnetic field and a conductor creates an electrical current . The energy source harnessed to turn the generator varies widely . Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity . Others use nuclear power, but there is an increasing use of cleaner renewable sources such as solar, wind, wave and hydroelectric . </P> <P> In 1868 a hydro electric power station was designed and built by Lord Armstrong at Cragside, England . It used water from lakes on his estate to power Siemens dynamos . The electricity supplied power to lights, heating, produced hot water, ran an elevator as well as labor - saving devices and farm buildings . </P> <P> In the early 1870s Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry . </P>

Where was the first power station built and why
