The right hon. Member may well have asked a very valid question. As I was saying, such a plant produces about a third of the gas over a 20-year period that a fracking well would produce over 7.5 years, but anaerobic digestion plants will produce gas continuously because the cows that provide the stuff that produces the gas continue to produce the feedstock, as do we from our own waste and our food. Therefore, anaerobic digestion plants do not deplete. A long-term strategy for gas supply security might concern itself with anaerobic digestion and biogas, rather than going for a gas bonanza. We ought to look at all of these factors when looking at the future of gas supply in this country.
