We do not have a working economic nuclear grid. So it is irresponsible to advocate a nuclear grid unless throwing hundreds of billions of taxpayer money at Bechtel and friends is your goal.

Load following is economic suicide when most of the costs are fixed, which is why nuclear plants tend to shy away from it.

And the off-shore wind currently being built is targeting +60% according to the manufacturers.

Sure, if you want expensive reactors. Much of the technological base on nuclear either: 1. Scales with square or cube laws. 2. Are essentially fixed. A 100 MWe reactor requires a very similar amount of security as a 1600 MWe reactor, mainte

China is large enough to keep nuclear as an option, no matter the economic considerations, but the amount China builds barely makes a blip on the radar compared to renewables. https://cleantechnica.com/2023/02/06&#

The ideological perspective would not exist if nuclear was economic. It is simply an easy boogeyman to blame. SMR are not looking that hot either, looks like the prevalent truth from the 70 years of nuclear construction: that bigger is bett

Or just use LFP batteries, like Tesla does in the majority of their delivered cars.

The problem is that renewables and nuclear are economically incompatible. They compete for the slice that is the cheapest and most inflexible, both requiring dispatchable power to fill the gaps. Renewables easily win this battle as the cost

I can confidently tell you that OL3 does not cost €40/MWh. The marginal cost for paid off nuclear plants are €25-40/MWh. The €13B construction cost ends up being more than €86/MWh, unless you decide to amortize it over 80 yea

With the $120 - 200/MWh nuclear costs, which is the averege price they require all year around, you can do many completely insane things from an energy efficiency perspective and still come out ahead. https://www.lazard.co

Given the state of Flamanville 3 and Olkiluoto 3 if Germany had chosen nuclear instead of renewables they would still be running close to 100% fossil fuels today. Yes, coming from the oil crisis in the 70s France chose energy independence t

Sweden has been continously exporting ~1-2 GW to Finland due to the hole OL3 caused in the grid due to the 14 year delay. There's no need for the power anywhere Finland can export it.
