The Australian government plans to build the world’s largest solar power station, a 1,000-megawatt plant that would generate three times as much electricity as the world’s largest solar electric plant, now located in California, Prime Minister Kevin Rudd announced.

Over all, the proposed facility would cost about U.S. $1 billion, Rudd said, and would generate electricity equivalent to a large coal-fired power plant.
