I'm not really sure though that energy prices can be controlled by govts.
(the comparison with the Poll Tax is somewhat irrelevant because the poll tax was 100% dreamed up by the govt, and was a new tax out of fresh air).
Energy is however a commodity, and prices are set internationally either by private companies, or other govts (eg Russia).
Yes there are taxes on energy, but that's just taxes, if they don't get the money there, they'll get it somewhere else.
So given that the underlying price is set by extra-govt entities, who have plenty of customers elsewhere, I'm not sure that most govts have control over energy they would like.
A better long-term solution is to a) Foster the use of less energy overall, better house insulation, electric cars etc and b) grow home-produced energy (wind etc.) if those reduce dependancies on oil and gas then that's likely a nice byproduct.
Of course these won't change by Oct 1.
So yeah, I get people are hurting, I'm just not sure there's a lot a single nation (which imports energy) can do much about it.
