The Atacama region in Chile—where it essentially never rains—is the sunniest place on the planet. By 2017, some of the solar power produced there will be sent hundreds of miles away to the subway in Santiago, the first metro system in the world that will get most of its power from renewable energy.

The subway, which serves 2.5 million commuters every day, will get up to 60% of its energy from a new solar installation and up to 18% from the nearby San Juan wind farm.

Though Chile is particularly sunny, the fact that a massive, power-hungry subway will be powered in large part by the sun is a testament to the rapid rise of solar as the cost of the technology keeps falling. "I think this is a sign of the mainstreaming of solar," says Tom Werner, CEO of SunPower, the California-based solar company that is designing and building the system.
