black-outs, extreme weather events such as record heat waves and storms, and ongoing climate change denialism within the ranks of the Coalition government that has caused an abject failure on climate and energy policy at the national level. A key contributor to the current situation was the decision by the Coalition to divorce energy policy from climate policy and remove a carbon price signal. Let us be clear: there never was any real-world rationale for the abolition of a carbon price. Instead, it was done for ideological reasons and base political gain. The schism wrought in Australian politics over climate and energy policy by the Coalition has been disastrous for political discourse in this country and is now having severe adverse economic, social and environmental consequences for the nation. Australia's existing electricity network was built to support the outdated and dirty coal-fired power stations. The world is moving rapidly to decarbonise electricity supply and the current owners of coal-fired power stations were quite emphatic in telling this committee (and the concurrent Senate Environment and Communications References Committee inquiry into the retirement of coal-fired power stations) that they are getting out of coal and have no intention of building any more coal-fired power stations. By definition, therefore, coal has no role to play in a secure energy future. Coal-fired power stations are being closed down and coal is in structural decline. The market has moved. Investors have now priced climate risk into their calculations about the sources of future electricity generation. Investors know that a price on carbon is inevitable, but the debacle around climate and energy
