Thank you.
I assume that we are moving now into a new era in terms of permanently higher energy costs, and then the consequent actions that we, as scientists, want to take to reduce our energy consumption. And it seems to me, really, with the way we do things in Britain, the change will be piecemeal. I suspect that this is a situation in which you don't need piecemeal change. You need an integrated look, a coherent look perhaps at all your energy taxes, and also at your income taxes and your benefits system.
I think the one thing that poverty really has put on the agenda in Britain in the last ten years is that when one comes to look at this, the whole question of what the distributional impacts are and how a change affects low-income households compared with middle-income or high-income households is now something that is routinely done. I think that's actually a very useful step forward. So in some sense, it's an integrated look and you have to make sure you pay attention to the distributional implications, particularly at the bottom.
