With respect, this is not an adequate answer. I'll ask the question again: specifically which items should I stop using? I have the usual things in my home, so perhaps you could tell me which are not necessary.
Consumption can be reduced in a number of ways many of them small and incremental, for example
turning the thermostat down and wear another layer, fit the windows with heavy curtains and pelmets, sweep up rather than vacuum every time, eat cous cous it can be cooked in a few minutes and use human power rather than electric kitchen gadgets, use energy saving bulbs or better still go to bed earlier, turn things off rather than leaving them on standby , smaller telly, get a wood burner and skip dive to collect the close to one million tons of wood dumped annually, walk or cycle, and so on and so on.
To be fair the government hasn't helped or could be accused of being two faced by forcing digital on us. It uses more power than analogue.
I do agree that bringing in TEQ's would cause a few problems but we had rationing before during the war and it worked.
It will probably have to be brought in by the back door so to speak as any party who say they are going to bring in rationing probably won't get elected. For example when Ed Milliband talked about freezing prices he should have said he would freeze prices for say the first 500 units (figure out of the air ) and allow higher than inflation rises above that. Should have kept the power companies happy and got the population used to the idea of limits to power usage .
