This photo is of a solar thermal power plant that, once fully operational in 2013, will be able to power 140,000 homes. Solar thermal plants generate energy from the sun by using thousands of heliostats (basically, curved mirrors) to concentrate sunlight onto a central tower (seen in the center of the circle on the photo) so as to generate steam. The steam is used to spin a turbine, which generates electricity--all without the use of fossil fuels. What's more, through the use of molten salt, the heat can be stored and released at night, generating power 24/7.
The problem is that this project, and most large-scale renewable power plants, use a lot of land...land that is often untouched and home to endangered flora and fauna. Below is a photo of the land on which this power plant was built before work began:
