Science turns sun, surf into green energy

Leigh Sheppard, of the University of NSW, estimated that 1.6 million of the solar devices, installed on rooftops, would be able to produce enough hydrogen gas to supply Australia’s entire energy needs. While other energy options under discussion, such as nuclear power, produce harmful wastes, the only by-products of this solar hydrogen technology would be oxygen and fresh water, Dr Sheppard said.

“It is the cleanest, greenest energy option for a sustainable economy.”
