there are a number of points raised by Members that I'd perhaps like to comment on quickly. Lee Waters and David Melding raised the issue that you still have to generate electricity somehow, and that's no good if you're generating it by burning fossil fuels, for example. Actually, absolutely, we need to move to non-carbon electricity generation, but the electric vehicle itself is far more efficient than the internal combustion engine, so even if you're burning fossil fuels, which we don't want to do, you'll probably be three, four, five, six or seven times more efficient in having an electric vehicle transferring that power onto the road rather than a petrol or diesel car.
