Australia went from 5% to 20% in 15 years. South Australia had blackouts during the 2016 summer due to fossil fuel (particularly gas) companies poor maintenance shutting them down during high heat scenarios. Their state government decided enough was enough and poured money into renewables. They got the very first Tesla grid scale battery from Musk in 2017, which saved their grid $48m last year. In October this year, their grid ran 100% renewable for 6 days. They are officially planning a regular 100% renewable grid in 2025.

Australia changed national government this year and altered their targets substantially. They injected $25b into renewable sources directly and received $85b on top in private investment as a result. Their energy regulator is now planning (not predicting, actively planning pole and wire infrastructure requirements, new regulation to control Rooftop solar and forcing fossil fuel, particularly coal, to stay idle) for 80% renewables in 2030.

It's attitudes like yours which are holding us back. Labour and private investment are waiting for strong targets.

You’re highlighting my point. 100% isn’t happening in 15 years. Australia isn’t going from 20 to 100% in that timeframe. 25 billion isn’t enough to cover most, if any US states to go renewable. You’re also not factoring in the economics or supply chain of switching. Lithium demand and other rare earth metals are already projected to skyrocket without coming close to getting net zero. Without new extraction technologies, we simply can’t produce enough materials to go 100% renewable in the timeframe you’re suggesting.

LNG/coal plants will be around in 20 years. That much is guaranteed. It’s better to force carbon capture, which will make those plants more expensive to operate, while reducing emissions as the transition happens.

The last coal plant in Australia is due to close in 2038. It's moved forward closure an entire decade in the last 3 years and they're talking about moving it forward again. LNG has shot themselves in the foot here, as they tried to game the federal electrical system during a lack of 'gas availability' (they chose to export it for higher prices) in June. They've just had their prices capped and a super profits tax is on the cards in early '23. LNG will be summer peaking only by mid-2030s. They'll be lucky if they're being used more than a month year.

I'm afraid you don't seem to see what's happening in the renewable space. Regulation globally is decimating fossil fuels because people are sick of them determining prices based on their profits. This isn't the 2000s anymore. The world is moving quickly and inexorablly to renewables. The war in Ukraine has galvanised Europe on it even more. Yes, in the short term (2-4 years) they will be more dependant. But they are spending hundreds of billions to get off it now because they're no longer prepared to have it used as a weapon a la Russia. America is the only major Western country now lagging in their ambition.
