> In the meantime the renewables have failed to produce a noticeable change in my part of europe

Skill issue in your part of Europe, then. In my part of Europe, https://grid.iamkate.com/ is currently reporting 95% non-carbon sources, 85% renewables, and a power price of −£12.03/MWh.

When it comes online, Hinkley Point C will have taken 20 years from first approval. Too slow.

In my part of Europe (Hungary), on a sunny day we have more energy produced from solar (on top of about 50% nuclear) than we can actually use. Sometimes we're 110% zero-carbon and it's because of solar and nuclear.

As of writing this comment our energy mix is 35.69% solar, 23.19% nuclear, 26.66% nuclear imported from Slovakia. The rest is hydro and solar from Austria and about 5% gas and biomass.

In my opinion clean electricity is an almost solved problem, especially as storage gets better.

More electricity in Europe comes from renewables than from either nuclear or fossil, with renewables rapidly approaching 50% market share. Several countries (even the non-hydro-heavy ones) are already showing multi-day periods where renewable electricity exceeds 100% of demand.

If your part of Europe isn't showing a noticeable change, perhaps it might be because your part isn't trying?

I don't know, but I've seen quite noticeable change.

First, you spend 20 years paying several times more for fuel and electricity because "we need to fight global warming" and "ensure energy security from those russians," and then they tell you, hey, global warming is actually worse than ever, and yeah, we are dependent on the russians.
