Also known as Concentrated Solar Power, Solar Thermal Energy technologies use mirrors or lenses to concentrate the sun's heat to a level sufficient to boil water and create steam, which can then be used to produce electricity by driving a turbine.

Solar Thermal Energy systems are currently regarded as a more cost effective alternative to solar photovoltaic cells and most large scale solar farms use a form of STE technology.
