I do not think that I said that the air in Beijing was flammable. I’m not sure that the hydrogen or, indeed, the oxygen content is so high that the air would catch fire or even explode. I was referring to a particular river, the context of which is well-known. My concern is that those who say that climate change is unimportant quite often take the view that environmental regulation is a burden on industry. I do not accept that. But again, I come back to this point: the wind blows; it’s free. The tide will be there as long as the moon is in the sky. There is a capital cost, of course, of putting in place the infrastructure to generate energy, but once that is in place, the generating costs are very low indeed. I don’t know what his alternative is. He hasn’t outlined it. He talks of coal. He did his best to wreck the coal industry. The reality is that we will never produce enough coal in the UK now to supply our energy needs. We would have to import it from countries like Australia. We would have to import natural gas from countries that are not looking to do us a favour. We would have to import more liquid natural gas from countries around the world. We do that already. Now, whilst I know the energy mix in the UK is going to continue in the future—and indeed, 25 per cent of the liquid natural gas in the UK comes through Milford Haven, and that is something that will continue in the future—I do not see the wisdom in saying what we need to do is to go back to the technology of yesterday, with the pollution of yesterday, and look to ignore the overwhelming weight of scientific evidence and put our heads in the sand. He is somebody who is proud, he says, to be British. Then let him display his pride by saying that he wants the UK to lead the way when it comes to dealing with climate change.
