The government has announced plans to pass an energy law designed to improve domestic and business energy efficiency.
The bill, which was outlined in the Queen's speech, will encourage homes and companies to improve their reliance on renewable energy sources and introduce a "pay as you save" programme with a number of energy conservation measures.
According to a statement from the Department of Energy and Climate Change, homes will be required to insulate windows and wall cavities, with the costs paid back through utility bills.
Liberal Democrat secretary of state for energy and climate change Chris Huhne said: "Energy security and taking real action to tackle climate change aren't add-on extras for this new government, but are vital to our national interest."
Prime minister David Cameron said he wants the new government to be the "greenest ever" and promised to cut government department emissions by ten per cent in a year's time. He also pledged to meet targets to cut overall UK emissions by 80 per cent within 40 years.
