Maybe. Maybe not. The cost of new nuclear power stations in Europe is crazy.
Import the technology of South Korea. They seem to have got the hang of it.

How Bad are Bananas?
The most radioactive of all fruit. (It's the potassium that does it). Each banana has 15bq of radioactivity.

But the presently low prices of electricity on the wholesale market are caused largely by the massive subsidies for wind and solar.

In other words, the market distortion that makes nuclear difficult to sell is a politically created one.

If, at some point in the future, politicians awaken to the fact that they are slamming the door on a very clean and efficient means of providing a base load, this distortion may yet be removed. Or knowing our politicians, replaced by some other crazy distortion.
First, electricity prices are not that low now. Second, all nuclear power in Europe was essentially built with state support.

Again, I have sympathy for nuclear power and maybe the stuff Gates is working on can work. But if it costs twice what renewables and gas cost, I am not convinced.

It would be interesting to see a breakdown of subsidies per MWh and over the lifetime of the installation.

The Chinese are already talking about transcontinental / intercontinental UHVDC links. Maybe a couple of decades from now it will be Chinese rather than French nuclear plants that keep the lights on in winter.

There are many subsidy-free renewable projects now. Or at least not anymore on feed-in tariffs, but with minimum prices for which the generator has to bid. Depending on location, solar can produce at 15 EUR/MWh.

Regarding Chinese power supplies, I pass.

Which one? the one about renewables or the one about CO2?

Do you remember if there were huge miscalculations regarding wind?
Without the Hot Air

As I recall most of the numbers were simply out of date, and the technology forecasts were on the whole too pessimistic.

I don't remember it having a big focus on wind, but I think carbon capture and improving coal power stations footprint was a big topic? Which was kind of spot on but also completely wrong, since the UK "improved" them by shutting them.

Late answer, but check these two plots:
- First: figure 5 of this data collection, energy sources for the UK by source

- Second: (taken from https://qz.com/347687/the-uk-now-imp...me-in-history/ )

It's not like the UK produces more green energy. UK gave up on producing energy by shutting down coal-fired powerplants, and now is relying for more than 50% on imports. So I am not sure the number of Without the Hot Air were that much off ... it stated that the baseload could not possibly and realistically created by renewables in the UK, and there we are.

While it is correct that the UK has declining electricity generation, it imports only about 10% of its needs. The graph you show is energy, and probably reflects the decline of North Sea oil and gas production.
