  • What Is Concentrated Solar Power?

    What exactly is concentrated solar-thermal power (CSP) and how does it work? Mirrors are used in CSP technologies to reflect and concentrate sunlight onto a receiver. In the receiver, the energy from concentrated sunlight heats a high-temperature fluid.This heat, also known as thermal energy, can be used to generate electricity by spinning a turbine or powering an engine. Water desalination, incre
