To be honest, it wasn't that great in 2010 either, but people often look back to when they were younger and remember the good things, not the bad. We have just come out of a pandemic & straight into a European war now, which wasn't the situation in 2010. Just trying to put things into perspective.
But where we have messed up (and this tory leadership farce isn't helping) is that back in February the government should have started emergency procedures to prepare for Winter 22/23. Something like the Manhatten project (1942-45) or Apollo in the 60's. Get fracking all the gas we can, get out all the gas under the North sea that we can - open coal mines too.* Put green issues on hold until the whole world accepts it needs to act together. We could have at least tried to get self-sufficient in energy by the end of this year (even if we didn't achieve it) & maybe even run a surplus to sell to France and Germany. Then we could have kept the costs right down, none of this £4000 energy bills for families, this winter.
It is absolutely bonkers that Germany buys energy off Russia (and us too in smaller quantities) the funds which they then use to run a war against Ukriane, we then send arms to Ukraine to help them fight back, Bonkers!
*Can someone explain to me how in the 2020s with all the ICT we have now it takes ten years to build a Nuclear Power station, (& probably by the French or Chinese!) yet Britain built its first ones in the late 40s in like 3-4 years!?
