News from Helsinki, Finland which recently became coal-free when the last two coal plants closed. The local government just released a statement that the coal exit led to very clear air quality improvements. Can you spot the coal exit in the graph of SO2 concentrations?

Here's a sneaky peak the next release of the GB Renewables Map, or should I say the GB Not Just a Renewables Map…
That's right, all types of power assets are coming to the map! Plus a whole bunch of other improvements.

Next time someone asks you about energy and land use, maybe remind them that the ~35 million acres that currently grow corn for ethanol in the US could produce ~15 PWh per year of electricity from solar photovoltaics. That's ~3.5 times more than *total annual generation from all US power plants*.

Seems like a load of rage bait headlines about pensioners being targeted to pay more road tax have come out today. I’ve read the articles and it seems that an increase *for everyone* is being presented as a raid on pensioners. What am I missing here? Am I being a bit thick?

I'm dead against the proposed new housing development near us but the group formed in opposition to it is so full of flag-shaggers, illiterates, reactionaries and general numpties that I'm actually coming around to the idea that some new neighbours might be a good thing.

Sorry Donald, what was that? I can’t hear you over the sound of you backtracking.
Closest anyone will ever get to an apology from The Orange ManBoy - now he should say something similar to the other 31 countries whose military he insulted

I don't think it nuanced to make up something called "super flu", to use it in official communications from the NHS, or to project out record bed numbers that would require a tripling of current growth rates to reach.
That's stirring up panic & it'll erode trust when things really do look bad.

Just imagine being the parent of a soldier from Canada or Denmark or Great Britain or France who was killed in Afghanistan in the one and only time Article 5 was invoked and the entire alliance came to America's aid, and hearing President Bone Spurs say this.
Trump on NATO: "I've always said, will they be there if we ever needed them? That's really the ultimate test. I'm not sure of that. We've never needed them. They'll say they sent some troops to Afghanistan and this or that. And they did. They stayed a little back, off the front lines."

If this chart doesn't terrify the oil industry, I don't know what will. India’s peak road-oil consumption per person will never reach Chinese peak levels.

If you think gas power is cheap, meet Keadby 2, the last CCGT gas plant built in Great Britain
It opened in 2023, after 5yrs of development, at a cost of £350m
Owner SSE says it would now cost 3.5x to build the same plant (~£1.2bn)

Compare & contrast. This is Trump’s demand for Greenland. And this is Hitler’s for the Sudetenland.
There is no difference. The language. The unstoppable need to dominate. The megalomania. It’s the same.
And Keir Starmer’s response is appeasement. We are in that moment.

Wind and solar power generation growth in China last year was roughly equal to the total power generation of France or Texas, and covered all of the growth in China's electricity use, even as demand grew at over 5%.
