If David Cameron hadn't, as he put it, 'cut the green crap' a decade ago, we'd be further along on renewable and nuclear and energy efficiency, and households would be paying less for energy, not more. So, I agree that we need to catch up, but the other side of the coin to energy generation is energy efficiency. So, can you say, Minister, how the forthcoming new Warm Homes programme might build on the success of the previous scheme, which delivered free home-efficiency measures like central heating boilers and insulation to more than 4,500 households across Wales?
