@DanielGarb Wonderful perspective, Daniel - thank you. Australian football is in good hands with this young squad who have won more hearts back home through this campaign and are now hungrier than ever for greater Socceroos success. The next golden generation is born, the future is ����💛

@Blue_Pie_Ninja @johnrhanger I’d like to push back on your view about nuclear and suggest it’s in the same category as coal - just stupid!

[Chris Meder @EVCurveFuturist]

For decades France’s nuclear fleet defined the concept of “baseload” power. Now something remarkable is happening across Europe.

French reactors are increasingly bending around midday solar.

Not because nuclear suddenly became weak.
Not because demand collapsed.

But because solar scaled so hard across Europe that the economics and physics of the grid itself are changing.

The old energy system was built around inflexible generation chasing demand.

The new system increasingly reorganises around:

☀️ ultra-cheap midday solar
🔋 batteries arbitraging time
⚡ flexible demand
🌍 continental interconnections
🧠 smarter grids

Even Europe’s largest nuclear fleet is now adapting to that reality.

This isn't about merely about replacing one generator with another. It’s entire electricity systems reorganising themselves around a fundamentally different energy logic.

France’s reactors are no longer just supplying power.

Increasingly, they are responding to solar. That alone tells you how far this disruption has already progressed.

@johnrhanger And yet there are politicians still advocating to build new coal fired power plants and nuclear, I just don’t get it…

[Mark Cometti @ComettiMark]

@FootyonNine Love that North are finally earning the recognition their supporters have been craving. The rebuild is over, our time is coming 💪🏼

[Mark Cometti @ComettiMark]

@GiorgiaMeloni That’s how you do it @AlboMP .

@Microinteracti1 Australia should heed this warning and reconsider the AUKUS deal. We are never getting those submarines…

44% of evening peak met by batteries. In California, world’s 4th largest economy. Not some tiny pilot project or a niche experiment, a global industrial powerhouse

If you’re still sitting in boardrooms or parliament banging on about baseload and the intermittency of renewables, you’re not just wrong, you’re a dinosaur

California's 44% isn't an anomaly. It's a preview of the 2027-2030 reality for every major grid overbuilding renewables

The "technical barriers" the fossil fuel lobby loves to cry about are gone. We are shifting solar and wind into the night at a massive, industrial scale. We don't need expensive, inflexible coal or gas to keep the lights on; we need more storage and we need it now - everywhere

South Australia wasn’t supposed to move this fast. Models assumed slow, steady, controlled change. Instead it’s already at ~74% renewables, hitting 100% around 74% of the time. Beyond targets. Beyond plans. When cost curves hit, the system doesn’t transition… it flips.

That’s where the models start to break. They assumed renewables would gradually take share. Instead they’re already setting the behaviour of the grid. Price, flow, stability… all increasingly driven by wind and solar. That shift wasn’t meant to happen this early.

And here’s the part most people still miss. Demand isn’t sitting back waiting for the grid to catch up. It’s starting to move toward it. What used to be a ~3.3 GW system is now planning for 6.5 GW and beyond, with long term thinking pushing toward ~25 GW.

SA already has way more generation capacity than it needs most of the time, which is why you’re seeing 100%+ renewables periods, negative demand events, exports to other states, and a surge in new battery plants. That’s a classic sign of a system moving into energy surplus mode.

That’s not normal growth. That’s a system being rebuilt for something bigger. Mining, green metals, data centres. Energy-intensive industries don’t wait around. They move to where energy is cheapest, most abundant, most reliable.

At the same time, the old intermittency argument quietly collapsed. Not through debate, but through deployment. Storage scaled. Batteries moved from experiment to infrastructure. Multi-hour systems are becoming standard, not exception.

Now the grid is doing things it wasn’t supposed to do this early. Negative demand. Excess generation. Exporting energy instead of scrambling for it. These aren’t edge cases anymore. They��re signals the system has already flipped.

This is why calling it a transition doesn’t quite fit anymore. It implies something slow, linear, predictable. What this looks like is a phase change. The models assumed gradual adoption. Reality followed cost curves.

China is winning on scale. No question. But South Australia is showing something just as important… what the end state actually looks like. A grid where energy becomes abundant at times, local by default, and detached from fuel markets.

@Microinteracti1 The next move should be for Australia and the UK to cancel AUKUS.

[Mark Cometti @ComettiMark]

@PaulineHansonOz You and @LiamRBartlett go together like pees and carrots, Pauline.

[Mark Cometti @ComettiMark]

@MineCooky Great perspective…

[Mark Cometti @ComettiMark]

@campbellclaret Why are world leaders not speaking out about this?
