Energy Efficiency

The right hon. Lady is right and, of course, this is not a black and white issue. However, the bottom line is that if one has a finite pot of money to spend, light bulbs do not represent the most efficient way to save energy or carbon. As she knows, the most efficient way of doing that is to insulate, particularly given that we need to do so much more for the fuel-poor and there is so much more that we need to do overall. We must be focused, given the finite pot of money available. I do, however, take her point.
