I will confess to being very surprised just how timidly the UK took the covid measures, I felt sure that there would have been far more trouble than we saw. However this is a different ball game, we are talking about millions of people already close to, on, or even below the breadline being pushed further into poverty. And having to make those awful decisions of putting the heating on, or cooking food because they can't afford to do both. That will push some too far, and it will have serious consequences.
And who do you suppose will end up paying for these measures? Congratulations, you've just made it even more expensive for ordinary folk to live.
18 degrees is practically balmy in some parts, you ought to know being originally from 'oop North....
Seriously though, there are lots of things we can do to reduce our energy bills, including reducing the temperature that we heat our homes. However many people are already in this situation, and don't have a lot of cloth to cut.
So the government is going to need to do more than simply say "use less", because those people on the line & unable to pay for their energy are going to get very angry & very desperate.
