The military coup in Niger has raised concerns about uranium mining in the country by the French group Orano, and the consequences for France's energy independence.
Currently we (UK) always run at least ~3GW of fossil fuels, as well as a surprisingly variable amount of nuclear, because of the inertia problem. That will be solved by 2025.
Britain is up to 36% renewables *on average* over the last year, and still building fairly quickly. Plenty of countries have much higher proportions of renewables. But they also have other ways of dealing with it, e.g. Denmark’s trick was always much more energy trading.
Iceland is 86%, Norway is 76%. It can be done, though these figures are inflated by geothermal and hydro, which may not be viable for the UK. Sweden is 63%, but that includes a fair bit of biofuels. California is already up to 59%.
Intermittency is a problem, there are lots of ways to manage it. Nuclear is one of several options.
The amount of lithium batteries needed to reach 100% is probably ecologically unreasonable, although several academic studies do talk about this. So we probably do need some nuclear, unless iron-air batteries or hydrogen pan out rapidly. Nonetheless, the idea that there’s a ceiling of 40% is way out of date.
@Ardubal @MattMastodon @BrianSmith950 @Pampa @AlexisFR @Wirrvogel @Sodis What you say about “40% volatiles” is a myth.
