Garnaut says renewables will cut energy costs to Whyalla steelworks by at least a third, and outlines plans for large scale solar, rooftop solar and pumped hydro and battery storage.
South Australia, which already gets around 40 per cent of its electricity supply from wind and solar, is supporting the idea of using battery storage so new housing estates do not need to be connected to the grid. Ultimately, this will save everyone money.
Energy storage systems may be a bigger game-changer for the electricity market than solar PV. An affordable system developed by an Australian company means households will be able to produce their own ‘baseload’ renewable energy supply.
