* UNSW study: Least Cost Electricity Scenarios for 2030

Associate Professor Mark Diesendorf, of the Institute of Environmental Studies at UNSW, said all fossil-fuelled power stations in Australia’s National Electricity Market could be phased out and replaced economically and reliably with commercially available renewable energy technologies by increasing the carbon price to this “medium” level.

This carbon price range is considerably less than Treasury estimates for measures that would achieve far less in terms of cutting greenhouse gas emissions,” he said.
