China has recently completed construction of the world’s biggest solar farm. Called Longyangxia Dam Solar Park, the operation generates 850 Megawatts of electricity, which for the uninitiated, is enormous. Containing over four million solar panels, the plant can generate enough power from the sun to run nearly a quarter of a million homes. The Guardian has a good look at the new solar park, part of China’s giant effort to clean up their electrical generation. As solar prices get cheaper, look for more of these giant installations to help take our planet out of the age of coal, oil and gas.
