The Liberals win in the South Australian election on the weekend has brought energy policy back into the spotlight with incoming Premier Steven Marshall vowing to abandon Labor's promise to lift the state's renewable energy target to 75 per cent.
Steven Marshall has also said he will bring the state back into the Federal Government's energy policy the National Energy Guarantee (NEG), which South Australia's Labor Premier Jay Wetherill had opposed.
The NEG, which will be brought to next month's COAG meeting, scraps subsidies and incentives for renewables and instead puts the onus on power companies to source energy from a range of sources including coal, gas and pumped hydro.
But now, new modelling by the energy advisory firm RepuTex shows Australia is set to beat its emisisons targets under what it calls a "do nothing" scenario, suggesting the NEG could be redundant.
Reputex says unless the emissions target is more ambitious, there's little need for what it calls the "complexity" of the NEG.
