Energy, use less--save more

the long version

Did you know that: our demand for electricity grows by about 3% every year? just lowering the temperature of your thermostat by 1 degree Celcius can reduce your energy bill by 10%? energy-efficient light bulbs last about 12 times longer than ordinary bulbs, and each one will save you about GBP 163 a year? almost 40% of all the heat that we buy to warm up our rooms escapes through our walls and roof space if they're not insulated? if we didn't leave our TVs and other gadgets on stand-by, we could shut down two power stations? We're all using more and more energy: charging up our mobiles.
