Solar Thermal Power Plant

The solar thermal power plant at Sanlucar la Mayor outside Seville, Spain. It is the first commercial solar thermal power plant in the world and can provide electricity for up to 6,000 homes.

The power plant uses solar concentrating devices with mirrors to catch the sun's heat, focusing it onto tubes filled with liquid. The heat from the tubes boils water to produce steam to drive turbines that generate electricity. This technology is currently cheaper than photovoltaic cells and the hot liquid can be stored to make electricity after sunset.
