I agree that there will be some form of windfall tax, spun to make it look like it was thought up by Tories.
That piece about people turning off their fridges is shameful. Not only is it is bad for people it is probably bad for the fridges and they will end up breaking down.
The one other big difference the Tories could make is to reduce gas and electric standing charges. British Gas send me this "exclusive" rip off offer to fix my rates.
