Concentrated Solar Power (CSP) is a form of solar energy technology that uses mirrors or lenses to concentrate the sun's rays to generate electricity. The concentrated light is then used as a heat source to drive a heat engine, such as a steam turbine, that generates electricity. CSP systems are typically mounted on towers and can provide a continuous supply of electricity, even after the sun goes down. This makes them a reliable source of renewable energy, especially in areas with high levels of solar radiation.
