There was chat about this a while back. The German (IIRC) scheme is to give everyone a free energy allowance (enough to cover average basic use), then use above that costs above the current rate. So the more you use the higher the cost, but that partly funds the poorest (also windfall tax on suppliers). Gives a real incentive to cut usage as well.
