When the renewable energy projects that began construction in 2016-17 are completed, that number will rise to 90%, according to Green Energy Markets which completed the first Australian Renewable Energy Index.
While renewable energy output in Australia has grown substantially, the percentage of renewable energy making up the power mix in the grid is much lower. The country still uses more fossil fuel power than anything else, but the transition to a cleaner mix is happening steadily. Ten years ago, renewables only made up 7% of the power mix nationally, but as of last month that number has risen to 18.8%.
Australia's renewable energy comes mostly from hydroelectric plants (40%), with wind (31%) and rooftop solar (18%) trailing behind. Large solar farms only account for 2% of the country's electricity, but with major projects in the works, that number will change drastically.
Australia has set a renewable energy target of 20% by 2020, but according to the Green Markets analysis, that goal will be met by next year.
As the country builds the necessary infrastructure to support its renewable energy generation like transmission lines and energy storage to balance the power loads, more clean power will find its way to homes.
