It's interesting because I'm very ideological about politics in the UK. I have a burning hatred for the party that just left power after 14 years to the point that would make most zealots look positively tame. However I will concede that the UK has made pretty good progress on energy transition with a fairly broad base of support from most major parties and a lot of that transition happened under the party I detest.
While the UK faces some ongoing challenges:
- Transmission bottlenecks in Scotland
- Dwindling opportunities for offshore wind construction
- Natural gas for heating in an old and poorly insulated housing stock
- Electricity prices tied to gas prices
- A generation of NIMBYs who don't want wind turbines ruining their view of transmission pylons and ecologically dead sheep pastures
- Lack of zonal pricing to incentivize more on-shore renewables
And needs to go further and faster I don't think energy generation falls into the same ideological divide there (though this may change with Reform UK and their questionable funding/astroturfing). Certainly net zero and 'green crap' remains contentious but from an actual building-the-thing perspective we're just quietly getting on with it.
