<p>Emissions reductions delivered by renewable energy</p>
19 Nov 2024

Since 2015, 40 GW of new rooftop solar and large-scale renewable energy capacity has been deployed across Australia, with the share of renewables in the energy system climbing from 16 per cent to just shy of 40 per cent in 2023.

This investment has resulted in emissions being 30 per cent lower today than they would have otherwise been without the renewable energy investment since 2015. In aggregate, this has resulted in over 200 million tonnes of avoided CO2 emissions since 2015, relative to if Australia had continued to rely on the 2015 power plant fleet. 


Australia's electricity emissions in 2023 were down by 30% thanks to renewables
The growth in renewable generation since 2015 is estimated to have avoided 55 million tonnes of CO2 emissions in the 2023 calendar year, relative to a situation in which we had continued to rely on the generation fleet in place back in 2015. This is equal to a 30 per cent reduction in electricity emissions
By the end of 2025 it is expected that renewable  generation will be more than three times greater than  it was in 2015 and its share of overall generation will be around 48 per cent.
This will deliver 75 million tonnes of emission reductions in that year relative to if we had kept the 2015 mix of generation plant in place. This is a 39 per cent reduction on electricity emissions. That is equivalent to reducing the emissions from all of Australia’s cars, light commercial vehicles, and aeroplanes to zero.
Emissions in 2030 alone will be 178 million tonnes lower as a result of the growth in renewable energy generation since 2015, with an aggregate emissions reduction of 998 million tonnes between 2015 to 2030.
That's if growth continues at the pace required to meet the Federal Government's target of 82% renewable energy by 2030.
