I see that the right hon. Gentleman agrees with me, so I do not want to chance my arm too much, but it does not help when he shouts across the Chamber to people that they should be showing leadership. They are entirely right to address and represent their constituents’ concerns in this debate, as we are in the early stages of potentially developing a new aspect of our energy supply.
I have a couple of final points to make. It is often considered whether shale is the answer to all our energy problems. This speaks to the point made by the hon. Member for North Warwickshire (Dan Byles) about the tenor of the debate sometimes. I do not think that that is a realistic suggestion. Sometimes, the language around the issue does not help. Suggestions that shale will yield cheap gas, or that an extrapolation of the US experience will apply precisely the same in the UK, do not stand up to much scrutiny. My hon. Friend the Member for Southampton, Test (Dr Whitehead) made a point about how gas is traded, which is one aspect, but there are a number of different factors that make it highly unlikely that the impact on costs here would be the same as in the US.
The Prime Minister talks, as he did yesterday, about making it easier for shale to be extracted. That is not particularly helpful or useful either. It should not be about making it easier; it should be about ensuring that it is done sensitively and appropriately. Members have mentioned the precautionary principle. I suppose that I would use the term “proportionate”. It needs to be proportionate. That is important. If it is not proportionate, it will not happen, and then the potential benefits may not be realised. It needs to be done proportionately and properly. We have had a couple of debates this week and I am sure there will be plenty more during the next few months. Some specific points have been raised with the Minister, and I hope that he will respond to them in those terms. If he does not, he may be in danger of stopping something rather than encouraging it.
