This stunning Lord Of The Rings looking PS10 Solar Power Tower in Seville, Southern Spain, is Europe’s first commercial concentrating solar power plant. Upon completion in 2013, the plant will produce enough energy to power 180,000 homes, equivalent to the needs of the city of Seville without producing one particle of carbon emission.

From ENS:

“Known as PS10, the project produces electricity with 624 large movable mirrors called heliostats. Each of the mirrors has a surface measuring 120 square meters (1,290 square feet) that concentrates the Sun’s rays to the top of a 115 meter (377 foot) high tower where a solar receiver and a steam turbine are located. The turbine drives a generator, producing electricity. PS10 is the first of a set of solar electric power generation plants to be constructed in the same area that will total more than 300 MW by 2013. Power generation will be accomplished using a variety of technologies.”
