The strike price for nuclear power from Hinkley Point C when it becomes operational will be £92.50/MWh. This has received a lot of criticism for being too high. With current wholesale rates at £385/MWh, suddenly Hinkley Point C doesn't look so expensive any more.

Cost of capital is a thing though. Much easier to raise money for a wind turbine or solar panel than a nuclear reactor. They're very efficient once running, but at that point they have investors and insurers to pay back.

“ In Germany, for example, during the first two weeks of September wind-power generation was 50% below its five-year average.” I wonder what folks in the past would have thought about the concept of ‘wind draughts’. Maybe they experienced similar things with their grain mills?

Dunno about grain mills, but sailers have long known about trade winds and the doldrums.

Including the ability to develop sails that allow taking advantage of Wind in the opposing direction.

But also in terms of cost? Nuclear power plants are not exactly cheap.

A NPP is an order of magnitude more expensive than a combined cycle power plant of the same power output. So even if electricity prices are high now because of gas constraints, that doesn't mean a NPP would have been a good idea. Europe should perhaps have diversified their gas suppliers, with more LNG.

Its more expensive to build because you know... a nuclear meltdown is a thing to avoid.

Or, if you want: Not building twice as many (wind/anything) was a major mistake. Nuclear power plants fail sometimes, just like the wind fails. In 2016 almost a third of the plants in France were offline at the same time, some for planned maintenance, some unplanned, and the peak prices were higher than now. All these things are fixable by overbuilding enough. There's nothing special or magic about nuclear.

Building more nuclear helps de-risk wind droughts. This isn’t specific to nuclear; building more of a different kind mitigates the risk.

Not really. NPPs as backup to wind would be horribly expensive. Wind droughts don't happen often; even the current price during them would not make a NPP pay off.

What would make sense is larger local stores of hydrogen, to be burned in combustion turbines during the rare wind outages.

In Austria, the price per kWh has quadrupled since May 2020, which is when I moved in to a new home. Unfortunately this [0] chart from my provider only goes back 12 months, but you can see even during this short time that the price increased from 5.81c per kWh to 12.43c per kWh, which is more than 200%. I checked some of my statements, and in May 2020 the electricity price was 3.13c per kWh, which represents an increase of about 397% compared to today's price.

They've been signalling a 40%+ gas price increase for the winter in the news here in Romania. For the poor people and pensioners who often live month to month this is tragic news. They don't know how they'll make it when they'll have to choose between food and medicine or heat.

We're working on reducing gas dependency, shortages and price fluctuations are one factor, but dependency on Russia is another. I do wonder how much our gas import from Russia is helping us keep the peace.

And keeping Russians and their "dominion" oppressed. Just shows how morally bankrupt Europe is, and with how smug Europe is that is really cringey.

They did. Not getting your harvest in while the weather was favourable was a real problem. Mill capacity was one part of that, there were several others.

And also because combustion turbines are a seriously nice technology. Heat exchangers are expensive. A NPP transmits heat across many fluid/solid interfaces: fuel rods to coolant, primary to second coolant heat exchanger, secondary loop to steam generators, and steam to cooling water in the condenser after the turbines. A simple cycle combustion turbine avoids all that. Even a combined cycle power plant puts much less heat through its steam bottoming cycle for a given power output.
