The signal types can be either analog audio or digital audio.' Audio broadcasting also can be done via cable radio, local wire television networks, satellite radio, and internet radio via streaming media on the Internet. Stations can be linked in radio networks to broadcast a common radio format, either in broadcast syndication or simulcast or both. 'Radio broadcasting is a one-way wireless transmission over radio waves intended to reach a wide audience. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity, and some use nuclear power, but there is an increasing use of cleaner renewable sources such as solar, wind, wave and hydroelectric.' It depends chiefly on which fuels are easily available, cheap enough and on the types of technology that the power company has access to. The energy source harnessed to turn the generator varies widely. At the center of nearly all power stations is a generator, a rotating machine that converts mechanical power into electrical power by creating relative motion between a magnetic field and a conductor.

'A power station (also referred to as a generating station, power plant, powerhouse or generating plant) is an industrial facility for the generation of electric power. The vector stencils library 'Stations' contains 110 symbols of communications equipment, generating, transmitting and receiving stations substations satellites and power plants for power generation and distribution and radio relay systems.
