Australian energy production by fuel mix

For the 3 months to 25 January 2023, the Australian energy market operator reports the following supply sources.


These three months are typically the best for sunshine and reasonable winds. Yet solar and wind generation are contributing only 20% of the country’s needs.

It seems to me that the only viable way to get the penetration of renewables up will be to shut down all coal and gas production. Then renewables would be close to 100%. An inconvenient side effect would be that we would have only a quarter of the energy that we have today.
