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 and laptops, keeping our rooms so hot that we walk around in short sleeves in the winter, or leaving lights on all day and night whether we are using the rooms or not. But the consequences of using so much so freely is causing our climate to change, and our energy bills to rise. There are many small things we can do which cost nothing but can make a difference. This book gives you over 100 tips for saving energy, money and the environment, ideas for taking it a bit further with solar installation or wind turbines, plus facts about our energy use and its impact on our climate.
