British official suggests wearing sweaters to keep save on energy LONDON, Oct. 18 (UPI) -- Amid concerns over rising energy costs, British Energy Secretary Ed Davey said he wears sweaters at home to keep his energy bill down. Davey said it is possible for people to save on gas and electricity by wearing sweaters -- called jumpers in England -- and switching energy providers after British Gas, one of Britain's so-called Big Six energy suppliers, announced it will raise prices above inflation, The Independent reported Friday. "I'm sure people do wear jumpers, I wear jumpers at home," Davey said in an interview with the BBC. We do need to help people with these bills, I'm extremely worried about them. We can use competition in the way we have but we can also make our homes warmer and we can use less electricity and gas by going energy-efficient, and that's what the government is trying to do. A spokesman for Prime Minister David Cameron's office said this was not official advice, The Guardian reported. "To be clear, it is entirely false to suggest the prime minister would advise people they should wear jumpers to stay warm," the spokesman said. Any suggestion to the contrary is mischief-making. The prime minister would point people to a range of things being done to help people with their fuel bills, such as legislating to put everyone on the best tariff for them.
