The new solar thermal power plant in Spain stands at 40 storeys high and looks as if it was being hosed with giant sprays of water from afar. Upon closer inspection, one realizes that this tower is reflected by a field of 600 gigantic mirrors, generating up to 11 Megawatts of electricity without emitting a single bit of greenhouse gas. That's enough juice to power up to 6,000 homes as the focused rays turn water into steam that subsequently generate power by turning the turbines. When the sun goes down, enough heat has already been stored in the form of steam to continue power generation for approximately an additional hour, although future advances hope to increase that time.

The largest series of solar installations in history, more than 1,300 megawatts, is planned for the desert outside Los Angeles, according to a new deal between the utility Southern California Edison and solar power plant maker, BrightSource.
The momentous deal will deliver more electricity than even the largest nuclear plant, spread out among seven facilities, the first of which will start up in 2013. When fully operational, the companies say the facility will provide enough electricity to power 845,000 homes — more than exist in San Francisco — though estimates like that are notoriously squirrely.
