In the spring of 2009, the world's biggest solar power tower, a tower that helps convert sunlight into electricity, launched operations near Seville, Spain. Imagine a scaffolding, a hundred meters high, that has a black circular receiver on top of that. Imagine around that central receiver you have a field of mirrors, flat mirrors , all of those mirrors basically pointing at this central receiver on top of this tall tower. You can imagine the sunlight striking these mirrors, redirecting that sunlight to this tall tower Mehos said the sunlight forms an intense white beam between the mirrors and the tower, and creates very high temperatures at the central receiver. That's the sunlight, the radiation, transferring before it’s converted into thermal energy. This thermal energy or heat, powers a steam turbine in order to generate electricity. The thermal energy can be stored for later use.
