Specifically stupid is to first cause doubling of price by saying "we are going to stop buying your product", yet keep buying said product for half a year, monetizing the other party in the process, more than ever per delivered product, to the point they can totally afford cutting the supply just for fun.

So 25%....so why not build another 3 x what we already have?...then isnt that close to 100% of elec supplied by wind?.........ditto other countries...like Denmark where 47% elec is by wind.
Denmark owns Greenland, which has an arctic coast, with loads of fossil fuels, which they could start flogging to us all if they wanted.

Or is it a NIMBY question...
And what about fracking?
I dont care if they frack under my bed, get the frackers back!

And solar isnt being used enough either, in all countries.

Why not more tidal lagoons like  Swansea Bay...

The answer to all the why not energy questions is that it takes time, measured in years, to build up that infrastructure. What does one do in the meantime? Worse yet, what happens to all that infrastructure in a few years when the cheaper sources of energy come back and they can't compete anymore?

As for fracking, it's got a history of negative effects, like contaminating groundwater (where does the UK get their fresh water?), earth subsidence, creating earthquakes, methane releases, and more...you can google that easily. To be used in moderation and foresight, or you're destroying one essential resource for another.

Numbers, not adjectives, rule.

The key word is dispatchability.

If you crunch the measured wind output in the UK (from gridwatch), there is a remarkably simple rule of thumb. If the peak output is X (currently X is approx 12GW IIRC), then for X%.of the time the wind output is less than  X% of the peak.

Yes, that means for 3 days a year the output is <1% of peak, I.e. 0.12GW. Where are you going to get the other 99% for those 3 days? Have lots of other generating plant lying idle except for then?

That's why whoever creates grid level energy storage will become as rich as Croesus.

Ive got a funny feeling that Russian gas has gone...forever, for UK/USA/EU

No Denmark does not own Greenland, they are part of the kingdom but have home rule and natural resources on Greenland belong to Greenland
