Renewables
Renewable energy sources accounted for 7% of Australian energy consumption in 2019-20.
Renewable electricity generation has more than doubled over the last decade, but combustion of biomass such as firewood and bagasse (the remnant sugar cane pulp left after crushing) remains more than two fifths (40%) of all renewable energy consumption in Australia.

In 2020, 24% of Australia’s total electricity generation was from renewable energy sources, including solar (9%), wind (9%) and hydro (6%). The share of renewables in total electricity generation in 2020 was the highest since levels recorded in the mid-1960s.
Solar and wind have been the primary drivers in more than doubling renewable generation expansion over the last decade. Small-scale solar generation grew by 27% in 2020, and by an average of 28% per year over the last 10 years. Wind generation grew by 16% in 2020 and by an average of 14% per year over the last decade. Hydro power output has fluctuated around a fairly consistent level according to rainfall and market conditions, losing predominance as generation sources diversified.
Recently, large-scale solar generation has begun rapid expansion. Large-scale solar generation has grown from negligible levels before 2016 to 3% of all Australian electricity generation in 2020, representing a four-year growth rate of 1,268%.
