“The basic idea [of Concentrated Solar Power] is to arrange mirrors so that they concentrate sunlight into a relatively small area and then use the resulting heat to raise steam to drive turbines and generators, just like a conventional power station. Direct sunlight is needed and CSP works best when sunshine is plentiful, as it is in hot deserts. In those kinds of conditions, CSP is currently the most cost-effective way of capturing solar energy but this might change in the future with further developments in photovoltaics (PV).”
