31 October

Last week South Australia got 99.8% of its electricity from solar (yellow) and wind (green) only. That's day and night, not just days. On Saturday it actually hit 264%, but because prices were negative in the grid because of so much supply, it didn't use over 160% of the renewables power it had available. It plans to use those huge surpluses to fill batteries and produce green hydrogen, to make green steel, which could make it very rich.
