My Lords, I thank all those who have taken the time to give us a very interesting and rewarding debate this afternoon. I cannot possibly reply to all the comments that have been made and will refrain from discussing climate change, even though I would like to do so with certain noble Lords—perhaps we will do that in private.
Quite a number of noble Lords have made Second Reading points this afternoon rather than points which relate to this particular amendment. Be that as it may, it is worth commenting on shale gas, which has come up several times. It is worth pointing out that shale gas
is about the most expensive gas to exploit that we know about on the face of the earth. You have to use a whole range of technologies which are mostly at the top of, or almost beyond, the range of conventional gas exploitation. The noble Lord, Lord Lawson, is absolutely right when he says—or implies—that gas is the least transportable of the fossil fuels. If you get your shale gas from abroad, you pay a premium of something close to $2 or $3. The real advantage of shale gas is to those who have it themselves and can put it straight into their national grid. If, in due course, we can do that, that will certainly be a help to the national economy. However, I do not see anything in this Bill that actually inhibits the future use of shale gas.
