Energy Bill [Lords]

I will make a little progress, if I may. Millions of homes, and millions of businesses, could benefit from the green deal in the next decade. We expect that households will be able to install measures worth up to £10,000. That is a massive undertaking, and it can make a real difference. Heating is the second biggest driver of energy demand in Britain, and British Gas pilots show that householders who put in energy efficiency measures can cut their gas consumption, and their bills, by up to 44%. That is a very substantial and significant saving, but so far energy efficiency has passed under the radar. We estimate that between £2 billion and £3 billion of energy is wasted every year because our homes are poorly insulated and inefficiently run. We may as well be standing outside our front doors burning £50 notes. That waste represents £2 billion to £3 billion of gas and oil imports that make us more vulnerable to the vagaries of global oil and gas markets.
