Reporter Stephen Long documents the revolution in power generation taking place across the globe. He travels to California, where successive governments have legislated to have one third of the state's power come from renewable sources. He meets the Australian entrepreneur who left home to create a multi-million-dollar solar company in the US. Stephen Long visits a massive solar farm that not only takes energy from the sun, but can also store it in a massive salt crystal tower. In time, the farm will power the bright lights of Las Vegas. Meanwhile, back in Australia the Federal Government is being lobbied by power producers using coal and gas to wind back the renewable energy targets that would see 20 per cent of this country's power generated by renewable's by the end of the decade. Little wonder they want the targets lowered. The explosion in wind farms and solar rooftop panels in homes across Australia has already cut the demand for electricity and left them with gold-plated infrastructure that can no longer be justified.
