Ketan... Could you pls engage with @johnquiggin.bsky.social on this? Could be an informative dialogue! "Can someone check my arithmetic, please. I saw recently that ChatGPT gets 2.5 billion queries per day. Rounding slightly down that’s 100 million queries per hour.

You've done it now, Richard. I'd rather go round saying "six-seven" than have to initiate such full-scale neural restructuring.

Good takes on IEA report, and some good questions, too. Scheduled for 30 mins, went for an hour, could have gone longer...

What a profound failure of imagination and principle for Labor to back in this utterly wrong-headed AUKUS business.

Yes, this story is a thing of beauty! PM dragged in, story spreading everywhere and the boot definitely ends up on Pocock's foot with his conditions for rejoining. A true bright spot in the day!

Chris - I adjust my late afternoon walk length to the show's duration - this episode will literally as well as metaphorically take me to places I've never been!

In India, each km driven using bio-ethanol uses up to 250 x as much land as an equivalent EV recharged by solar - ieefa.org/resources/in...
India’s ethanol roadmap off course
Land is used far more efficiently generating renewable power for EV batteries than growing crops for ethanol.

Transporting coal is very profitable for Indian Railways, but also an enormous problem, producing major congestion and crippling the passenger network. ieefa.org/resources/co...
Coal: A heavy burden on the Indian Railways
Indian Railways could better serve the country’s changing economy if policymakers focus on accelerating renewable electricity generation rather than expanding the transport of coal by rail.

Well done Anthony Klan. Simply appalling that someone funding such a destructive, biased and repulsive political lobby group should have any taxpayer-funded position of influence.

Yes, it is a significant competitor for food and fodder crops. Sugar cane was the staple for ethanol production, rice is also used and increasingly, maize, which used to be exported. Worse, compared to solar for EVs, ethanol in India is massively more land hungry - ieefa.org/articles/iee...

Ketan, you'd be thrilled to have read the editorial in today's Australian (I read at my ☕ shop to see what the other side's up to). Touting two industries for the country's future: gas and AI. Clueless.

I think it's much worse than overlooking them. They purposefully downplay the effect of Australia's cynicism on other governments' commitments . It isn't about our 1.3% (domestic) or ~4.5% (exports) contribution, it's also about moral and diplomatic leadership of a formerly respected middle power.

It was a great piece. Deserved to be picked up. Loved Ben Eltham's 'gas-flare on the hill', too - or was that a sub-editor? Good either way.
