T_L,
you're implying Covid19 is the catalyst for power cuts, we're not having power cuts in the UK because it's maxing at 23c at the moment, not >27C. We don't have the seasonal demand in hot weather that A/C creates, yet.
Water shortages aren't exactly a new problem in Oz but you have to bite the bullet and accept that desal is the way to go,albeit at greater cost; or you can do rain dances all night long hoping that global warming is just a fad.
46k deaths and still rising in UK and 2nd wave definitely starting in Europe; Until folk start taking lockdown's seriously it's not going away - the only thing that will reset the whole equation is a vaccine, UK PLC and most of
Europe can afford to fund a population wide vaccination program, Africa, Asia? That's a different question entirely, especially as the WHO is already woefully underfunded.
Against this background, can't see any normalisation in the near future.
