An absurd conspiracy theory.

Nuclear power has an LCOE that is 5x the cost of solar and wind. Nobody would build it on cost alone.

The only reason countries build and run nuclear power plants is because it shares supply chain and a skills base with the nuclear military.

Which means they have nukes (France, Russia, US) or they they want to take out an option to one day build a nuke in a hurry just in case for a threat that is usually very obvious (Sweden, Japan, South Korea).

This was clearly recognized when Iran started building nuclear power plants but when Poland suddenly got interested in 2023 ostensibly "because environment" after decades of burning mountains of coal nobody batted an eye.

> when Poland suddenly got interested in 2023 ostensibly "because environment" after decades of burning mountains of coal nobody batted an eye.

Polish discussion about nuclear energy has always been openly tied to national security and energy independence, given its/Europe's reliance on Russian energy exports. Especially given its northern geography, nuclear is better for base load stability. (The environmental is also important, and strides have been made to reduce emissions.)

Of course, there has also been discussion in Poland about nuclear sharing or even seeking to acquire/build nuclear weapons itself, also openly, but I don't think anyone is actually pursuing this in earnest.

Solar and wind are intermittent. Grid scale energy storage is not even a thing yet.

That's not much. Projects listed there can't store energy for winter needs.

Neither could French nuclear plants when they were turned off for weeks at a time for emergency maintenance.

So, France fired up the gas.

5x cheaper electricity, on the other hand, makes power-to-gas economic, which can smooth out seasonal variations in a carbon neutral way.

Isn't power to gas still ridiculously inneficient?

Last I checked it seemed like something pushed by gas companies since it upholds gas infrastructure and most of the intermittence is currently supported by gas.

It's very costly compared to normal gas but it's still marginally cheaper to use solar and roundtrip p2g to use on a cold, windless night than it is to use nuclear power produced on any day of the year.

There's just zero economic incentive while polluting gas is dirt cheap and maxxed out solar and wind rarely even covers 100% of current electricity demand.

It's windy and sunny in the winter too.

Ahhhhhhh . . . it's Australia.

Winters here have more sunshine than UK summers.
