My Lords, I will speak briefly on Amendments 50 and 51. My heart is with them completely, and I congratulate the right reverend Prelate on his award. I am sometimes involved in green awards and energy efficiency—an area that has often been left out of these debates—and it is great to have someone who has been a recipient of one of those.
The difficulty with these two amendments is that they target a specific reduction in electricity. Coming back to the decarbonisation debate that we had earlier on today, better decarbonisation can, of course, actually be achieved by having an increase in electricity. One of the big challenges of decarbonisation is moving the transport sector from fossil fuels either into biofuels or, particularly, into electricity, using electric vehicles. We also eventually want to move home heating from gas into electric—non-carbon-generated electricity. It therefore makes it very difficult in these areas to have targets on terawatt-hours or proportions or whatever; you have to take it back to exactly what the right revered Prelate said, which is energy efficiency. I am a great advocate of the green deal, and it certainly has its issues at the moment and I hope it succeeds, though perhaps it needs a number of changes to do that. At the end of the day, however, the real thing we have to do is just to go out there and, perhaps rather brutally—whether it is street by street or village by village—ensure that we upgrade domestic and industrial premises so that they are energy efficient. Going down the route of specific electricity- target reductions could actually work against decarbonisation and the way in which we are trying to reduce carbon emissions in this country. I am absolutely with the intent, but I think the method in this case has great difficulty.
