Its a wake up call to invest in the long term. We had a chance to have tidal, nuclear and other projects running by now (they were proposed decades ago) instead we just stagnated and thought about short term profits relying on cheaper fossil based fuels.
Yep and now we're all paying for that short-sightedness.
The daft thing is that the big COL subsidies the government will need to dish out to cover energy could pretty much be used to pay for solar installations on the majority of households in the UK. That'll then mean less reliance on other generation, and will probably go a very long way towards reaching net zero emissions.
