Energy Efficiency

The hon. Gentleman is right to say that some very exciting developments are taking place in lighting, not the least of which will be light-emitting diode—LED—technology in the longer term. However, we must be brutal and realistic in the use of CERT; we must opt for the most effective, most value-for-money carbon abatement schemes. That means opting for loft insulation, because any exercise that one chooses to undertake shows that key insulation delivered to our constituents' homes offers the best value for money and the best use in terms of carbon abatement. We have to be far more focused on that. I checked how many light bulbs had been distributed as a result of the previous CERT scheme and I found that the answer was a phenomenal number. This begs the old question of how many light bulbs it takes to change a Labour Government—the answer turned out to be 262 million.
