New analysis from research firm Bloomberg New Energy Finance has concluded that electricity from unsubsidised renewable energy is already cheaper than electricity from new-build coal and gas-fired power stations in Australia. The modeling from the BNEF team in Sydney found that new wind farms could supply electricity at a cost of $80/MWh -- compared with $143/MWh for new build coal and $116/MWh for new-build gas-fired generation. These figures include the cost of carbon emissions, but BNEF said even without a carbon price wind energy remained 14% cheaper than new coal and 18% cheaper than new gas. "The perception that fossil fuels are cheap and renewables are expensive is now out of date," said Michael Liebreich, chief executive of Bloomberg New Energy Finance. "The fact that wind power is now cheaper than coal and gas in a country with some of the world's best fossil fuel resources shows that clean energy is a game changer which promises to turn the economics of power systems on its head," he said.
