"Solar PV is different from other electricity sources — in one crucial way. Every other commercial source of electricity — besides solar PV — generates energy through roughly the same means: by spinning a turbine."

"Coal plants, gas plants, nuclear plants, and concentrated solar power plants are all just different ways of boiling water to produce steam that spins a turbine. Wind power harnesses the wind to spin a turbine. Hydropower dams use flowing water to crank a turbine. These spinning turbines, in turn, provide mechanical force to an electric generator, which translates it into electrical current (this is done by moving electrical conductors through magnetic fields"
