My hon. Friend hits upon a crucial point. If we are to have clean growth and a sustainable pathway towards net zero, we must ensure that we continue to use gas. We have weaned ourselves off coal, and it is remarkable that we went 18 days and seven hours without coal—not that I was counting. Anyone can follow the reduction in the use of coal over the past seven years, which has happened because we have been able to adapt and put gas back on the market. Going forward, we will have to ensure that we invest in a multitude of energy sources, including solar and other renewables, but gas will be a vital part of the mix in a sustainable transition.
