dont usually venture in here but my take on the gas crisis;
yes there are increased demands in Asia right now, i would say that is more to do with the current replacement of coal going on out there, not as much to do with increased demand after covid (although that is a smaller factor, which shouldnt be a long term issue at all).
In the UK, a large share of our power generation comes from natural gas (40 to 50% depending), which is higher than all of the EU countries. Only Italy really comes close on about 35% (other high price country right now). This is probably not a sensible dependency level.
Importantly, the UK has a very very small gas reserve, perhaps only a few days for some gases (methane, CO2) and a little to no long term natural gas storage (big north sea reserve was shut a few years ago when it also stopped producing)
Yes we've had a much less windy summer effecting wind power gen and increasing pressure on other fuels.
Not being in a larger trade bloc does give the UK less protection from volatile prices (probably).
finally, there is always the slightly conspiratorial reason that Moscow purposefully throttled gas supply, traditionally made over the summer to Europe, to force through the opening of NordStream 2, which hasnt happened
