Between 2009 and 2018 electricity generation emissions decreased by 30.2 Mt CO-e (14.3 per cent) from the peak in 2008-09 despite continuing population and economic growth. This was primarily driven by an 8.0 per cent increase in the share of generation of renewable energy in the National Electricity Market, with the largest increases coming from wind and solar, and a 1.8 per cent increase in the share from natural gas. This has coincided with a 9.8 per cent decrease in the share of electricity generation from brown and black coal, following the closure of twelve coal fired power plants between 2012 and 2017.
