Australia is seeing a faster than expected shift toward renewable energy. Recent data shows that wind and solar have supplied approximately half of the nation's electricity for two consecutive quarters, while coal usage has dropped to historic lows. This transition is being driven largely by the widespread adoption of rooftop solar. The rapid shift highlights a growing gap between public energy adoption and current political stances on decarbonization.

Half the electricity from wind and solar is a big number, but we need to see the peak demand data. Rooftop solar is great for the midday slump, but it does not solve the evening ramp. I wonder what the current curtailment rates look like in the sunny states.
That is the core issue. The incentive for rooftop solar was the feed in tariff, which worked for the consumer but created a headache for grid operators. We are now moving from a phase of simple adoption to a phase where we need better market design for storage.
It is interesting that the people voted with their rooftops. Most of this happened because the payback period for solar became a no brainer for the average homeowner. If we can get that same cost certainty for heat pumps, the gas transition will move just as fast.
The piece basically says the public has moved on from the old energy debates while the opposition is still stuck in the past. It is a practical shift in the energy mix that is happening regardless of the political rhetoric.
