France decarbonized way before the rest of Europe with nuclear and it wasn't expensive. 50 reactors for $200 billion. Gernamy has spent twice that on intermittents and still relies on coal
Such a tired point. It’s not the 1970s anymore, and the west can build any large projects cheap. Go look at the projected costs for France’s new fleet, and that’s before the inevitable cost overruns
"EDF estimates EPR2 programme cost at EUR72.8 billion"
France's EDF has said its preliminary cost estimate for the project to build six EPR2 reactors at Penly, Gravelines and Bugey totals EUR72.8 billion (USD85.3 billion).
Each reactor outputs 1650 megawatts of electricity running at full power. Assuming they run at 92% capacity factor, that's $9.38 per real annualized watt.
Great. So 538TWh per year is 61 GW so roughly 61 GW * $9.38 = $576 billion staggered over the 80 year life of nuclear plants is $7.2 billion per year of capital expenditure.
For comparison, wind is about $5/W. Assuming a 35% capacity factor and a 30 year expected lifetime for the latest turbines that comes to $10.0 billion per year of capital expenditure with no storage or fossil backup systems or extra capacity given weather variability.
PV solar is between $.97 and $1.16 per watt, so that's going to be the front line. With storage you can get from $1.60 to $2. This is already the bulk of the power generation in Europe and is only going to increase. The idea that you're going to run nuclear plants at 95% capacity factor economically is also very suspect in a continent saturated with cheap PV solar.
US NREL Puts it at $2/W with no storage and ~20% capacity factor. Lifetime of latest panels is unknown but optimistically is 25 years. Assuming perfect and free storage that comes to $24.4 billion per year of capital expenditure for a country the size of France to be 100% solar. So no, it would not be more economical to use solar over nuclear. Wind would be better but when you add the full system costs of storage and backup intermittent heavy systems are vastly more expensive and emit more carbon than nuclear ones.

Intermittents are only gaining market share because their unreliable and intermittent power which is less valuable is being purchased by governments at prices that far exceed what it is worth. In other words, massive hidden subsidies. Without those, there would be next to no intermittents on the grid anywhere.
