With rapidly rising oil prices and advances in solar technology, solar power generators are becoming an increasingly desirable option for nations’ energy needs, and Spain is showing the rest of the world how to make the most of it.

Earlier this year the Sol10 Solar Tower became the world’s first commercial solar plant to provide electricity for the national grid. 624 solar mirrors, known as heliostats, concentrate the sun at the top of a 35 storey tower, where water is heated to around 250 degrees centigrade. The steam produced drives the tower’s turbines, which create enough electricity to power a town with a population of 10,000.

The tower, which is located west of Seville, costs around three times more than a coal fired plant to build, but saves thousands of tons of CO2 each year – and now five more similar plants are planned for the same area in the next five years.
