My Lords, I have tried to follow the noble Lord very carefully. I will write to the noble Lord if I get it wrong, but I understand that the average saving of around £50 relates to what energy companies themselves have pledged to pass on. I will have to go back, read Hansard and revisit what the noble Lord has said.
My Lords, does the noble Baroness agree that we not only need competition between companies, as she has said, but between different sorts of fuel and sources of supply? We have seen in the United States the very beneficial impact of fracking in diversifying both sources of supply and sorts of fuel. We have great reserves in this country. There are, of course, difficulties about extraction and differences between this country and the United States, but we have riches under our own earth. Does the noble Baroness agree that, in the longer term, the best thing we can do is exploit them?
My Lords, my noble friend is right that we need a broad energy mix and shale gas will be part of that once we have ensured that it is safe and environmentally safe to extract. That we recognise the need for a wider energy mix is shown in the establishment of the Office of Unconventional Gas and Oil.
