Ed Davey, the Energy Secretary, has pleaded with energy companies to explain their profits ie to be more "transparent".
Ofgem has also been criticised in a report by MPs on the Energy Committee, for failing to do enough to tackle profiteering by energy companies.
That's all very well, up to a point. However, the MPs seem to forget that taxes and green energy surcharges also add to the financial burdens of the hapless energy consumers.
