"Renewable electricity generation is at record levels in Australia. Renewables
produced 36% of the nation’s electricity in 2022. Solar photovoltaics (PV) had
the highest renewable contribution (about 15%) and are expected to keep growing
in coming years.
But the increase in the share of grid-connected renewables adds to the
challenge of maintaining a stable electricity grid, given the impact of weather
conditions on their output.
An increasingly important question is what impact will climate change have on
weather-induced inconsistencies in solar generation? Our newly published
research is the first to quantify climate change’s impact on solar resource
reliability in Australia over the next century.
We find that as the climate warms, in some regions of Australia there will be
more weather-induced variability than in others. In particular, the eastern
parts of Australia can expect fewer intermittent or lull periods of solar power
generation by the end of the century. By contrast, some regions in the west
will face prolonged periods of minimum-to-no power generation in the future.
Despite the changing climate, the good news is the future of solar power looks
promising in most of Australia. Our research suggests solar resource
reliability will increase in the regions where we have our existing solar
