Photovoltaic systems create electricity when the sun's energy strikes silicon and creates an electric current. Concentrated solar devices focus the sun's energy on water or another medium, using it to create steam and power electric turbines. Solar heating systems warm air or water with the sun's energy for home or industrial use. There are even solar cooling systems that use the sun's energy to drive warm air through substances that cool the air through chemical reactions.
