It is a great pleasure to follow the right hon. Member for Kingswood (Chris Skidmore). I agree with every single word he said. If we do not work together on this, we really will be failing our constituents.
I support this big, important and complex Bill, but the test we should apply is very simple: will it give us the tools we need to achieve energy security in a net zero future? As the right hon. Gentleman said, we know exactly what needs to be done. We now need to get on and make it happen.
Some of the policy changes have turned out to be quite simple. The decision to say that petrol and diesel cars cannot be sold after 2030 has been brilliantly effective, because it has led to a huge increase in innovation and to new electric models coming on to the market, but other areas are much more complex.
I will address my remarks to the transition in home heating, which is intensely personal to all our constituents and, indeed, to all of us. There are currently 23 million homes in this country that are dependent on gas for their heating, which we know will have to change because the point will eventually come when no more natural gas comes through the pipes. The policy question is, what will replace that gas? Will it be electric heating, in the form of heat pumps or electric boilers? Will it be district heating? Will it be, for some consumers, hydrogen?
