With the cost of energy generated from wind and solar now less than coal, the share of Australia’s electricity coming from renewables has reached 23%. The federal government projects the share will reach 50% by 2030. It is at this point that integrating renewables into the energy system becomes more costly. We can add wind and solar farms at little extra cost when their share is low and other sources – such as coal and gas generators now – can compensate for their variability. At a certain point, however, there comes a need to invest in supporting infrastructure to ensure supply from mostly renewable generation can meet demand. But by 2030, even with these extra costs, adding new variable renewable generation (solar and wind) to as high as a 90% share of the grid will still be cheaper than non-renewable options, according to new estimates from the CSIRO and Australian Energy Market Operator.

Global renewable energy generation is expected to grow by seven per cent in 2020, further bolstering record shares of the power mix for clean power sources after plummeting electricity demand during the coronavirus crisis saw fossil fuel generation marginalised. That is one of the top line conclusions of a new global electricity markets report published today by the International Energy Agency (IEA), which summarises the influential organisation’s projections for the full year.
