Cheap energy efficient measures such as installing low-energy light bulbs could reduce the UK's carbon emissions by up to 40 megatonnes a year, according to new research.
The Grantham Institute for Climate Change at Imperial College revealed that reducing electricity usage is up to 60 per cent more effective than previously thought and simple measures such as turning electrical appliances off at the mains can significantly contribute to lowering CO2 emissions.
The institute said such simple lifestyle changes could have the same impact as removing around ten large gas-fired power stations from operation.
Installing ten energy efficient light bulbs could save up to 350kg of CO2 per year, the research found, while turning off all devices at the mains when going to bed or on holiday could save 100kg of CO2 per year.
Adam Hawkes, a visiting fellow at the institute, told the Independent on Sunday that the government has misjudged potential greenhouse gas savings because it missed out the fact that different types of power stations emit varying quantities of carbon dioxide.
