The UK doesn't have great solar energy potential because of the high latitude and general lack of sun. Wind is much more practical in this country however like solar it provides it's a non-stable energy source. To have a stable energy grid you ideally want a mix of stable and non-stable sources or non-stable sources and large battery storage facilities.

But that would solve something. And that's not wanted.

So instead we will lament ballooning costs and build times for nuclear and invent narratives how that's totally not caused by nuclear being a shitty alternative to renewables and storage.

This way we can spend another few decades on building a none-solution while just accidently also having sunk so much money already that changing to an actual solution doesn't make sense anymore.

Oh, sorry. Were we expected to stop burning fossil fuels? Doesn't seem to work for some reason, but don't worry. Building nuclear will totally solve this. Any decade now... (And no, we totally did not build to little anyway, just to make sure it will never solve anything even if the unimaginable happens and build times and costs become manageable...)
