The right hon. Member is absolutely right that we need to test these things and take the environmental benefits as a whole, but these tests have pretty much been carried out, and there is an overwhelming
environmental benefit to solar, which is a cheap and reliable power source. By the way, the batteries associated with it that make it more reliable do not need to be sited in the same place as solar farms, so things can be designed in such a way that the environmental disbenefits are not all concentrated in one place.
