No telling people just to use less isn’t really much help.
in theory it could ..... if everyone used a little less energy*** - even those who can afford to pay - then demand would drop in electricty. if demand for electricity drops then its cost drops - as most here will know, if demand drops too much energy companies have to PAY money, hence agile tarrifs can go negative, to encourage people to use more energy off peak so they dont have to pay to shut down wind turbines etc (according to my app in the interests of fairness it hasnt gone negative for some time!!!).
you are right that telling broke people who are already using very little electricty will do naff all
*** and i am not claiming to be perfect here, sitting at home working in my home office with laptop, pc and 2 screens all on......
i do wish people would stop blaming green levies tho. over all its not a huge amount on our bills, and actually if we had more renewables this wouldnt be a problem..... I was told for years by friends that solar just does not work in the uk, and i can tell you after having it for 13 minths ........ utter nonsense!. my solar panels have covered 60% of my energy usage, and i was a fairly high energy user (in 12 months generated 4600kwh and i have consumed 7600kwh in total so that is a huge chunk of my electricity use self generated). (WFH hasnt helped my electricity use as my home office is heated by electric.... but better that than my 34miles round trip in a diesel car)
obviously not everyone is in a position to get solar, either cant afford or dont have a sensible house, but all those who CAN get solar should really consider it with the knock on effect of it helping those who are tied to using the grid, and long term will be an investment as well. its a win win.
I have no problem a small percentage of my bill going to green levies... much rather that than paying subsidies to fossil fuels - which is a thing as well.
my goal is to reduce my electricity consumption by 20% this winter............. which should be doable i think.
