@ frank
So, if "energy is far to cheap", your proposal is to tax it to the fucking hilt, forcing people to use less of it (or so you think).
Reality.
Those of the general population who are at the financial bottom of society get faced with a stark choice then, particularly in winter. Starve or Freeze?
The poorest members of our society are already facing that choice with ever increasing fuel & food bills (nice two-edge sword there), so your proposal is to tax them even further? ("I also recognise that the only way to get people to change is to make so painful not to change that they have to."). Just how much 'pain' is enough, Frank?
Starvation? Hypothermia? DEATH??
Oh, by the way,your statement "The difference between you an' me is that I realise just how screwed we are and recognise the need to change.", presumes that my opinion on that is different from yours, WRONG!
We DO WASTE ENERGY. We DO need to do something about it. But taxation IS NOT the answer. Neither is trying to heat a room with two fucking candles. We need REAL WORLD solutions. I don't think "we're screwed" though, not quite. But if we go YOUR route, there'll be a shitload of people who WILL BE!
We didn't get into this overnight, we won't get out of it overnight either.
