A national target to deliver 33,000 GWh of large scale renewables will mean that around 23.5% of Australia’s energy generation in 2020 will come from low emissions sources. The target has accelerated development of large projects that fit with natural resources, including wind energy installations, solar farms, and a proliferation of rooftop solar power. On average, around 23% of all homes in Australia have rooftop solar PV systems. In South Australia and Queensland, the proportion is closer to one-third.
A number of states and cities have targets specifically for energy generation:
- South Australia – 50 per cent of state’s electricity generation from renewable energy by 2050
- Queensland – powering Queensland with 50 per cent renewable energy by 2030
- Victoria – 25 per cent renewable energy by 2020 and 40 per cent by 2025.
- City of Sydney – 50 per cent renewable electricity by 2030
- City of Melbourne – 25 per cent renewable electricity by 2018
- Canberra – 100 per cent renewable electricity by 2020 (on track)
The world’s largest grid-scale lithium-ion battery is being installed in 2017, connected to a large wind farm in regional South Australia, marking a significant shift to renewables plus battery back-up into the national grid.
Significant expertise has been developed in energy supply in planning, finance, installation, project design and grid integration. In energy efficiency, there is extensive Australian expertise in technology, building management, data systems, behaviour change and financing.
