We would need to build much , much more storage, and I hope you know water dams are not easy to build(a lot of humans and wild life needs to be moved), if you don't already have them probably is impossible to create them.

>A week of no solar power or wind is unheard of. A week of no wind is very very rare.

You don need no solar or no wind, you need a few weeks of super low solar and wind, like say in winter, solar efficiency is much lower in winter.

We would need much much more of anything to make our power fully renewable.

It's still cheaper and faster building pumped storage, wind and solar (all < 7 year lead time) than building nuclear plants (up to 20 years).

This is not even accounting for the nearly free insurance granted to nuclear plants putting taxpayers on the hook for costs like the $800 billion cost of dealing with fukushima (which involved burning a lot of coal and gas).

The economics of nuclear power as green energy only really make sense because it lets you share some of the rather high costs of maintaining a nuclear arsenal. The environmental movement is being coopted/guilted into supporting its subsidization.

Any numbers on that pumped storage? how much is needed to store 1 week of France energy needs ? How much it costs then?

[ZeroGravitas]

France has never generated more than about 75% of its electricity (not power which is much lower because of diesel cars, fossil heating etc.) with nuclear.

It regularly imports electricity from its neighbours, as well as selling its surplus (which it has even at only 75% electrical because the supply doesn't match the demand peaks.)

The current best nuclear rollout on the planet falls far short of your test for being able to run France for a week, has never passed that test, and will never pass that test so why is this considered an argument against renewable plans?

[simion314]

There is no anti-renewable plan. I want to install a solar roof, my brother has one already, in summer he sells electricity but in winder he has to buy. So what happens when we all have solar roofs or we are powered by solar and is winter so cloudy for 2 weeks?

It is obvious that private companies or people will not buy some extremely expensive batteries for 1 week a year, it will not make economic sense. T he country needs some power plants that could work extra in winter or low light conditions, or we all buy 3x more solar panels and expensive batteries.
