Homeowners can do their bit for the environment simply by turning off kitchen taps as soon as possible, it has been argued.Victoria Loustalot of takepart.com claimed that making green changes in the kitchen is often easier than a doubtful climate-change denier might think.Indeed, she noted that while it only takes a couple of seconds, turning off an oven, stove and kitchen tap at the first opportunity can contribute to overall energy-saving measures.Do this first, and then you can go right back to chopping, dicing, or plating your meal, with no harm done, advised the writer.Elsewhere, it was suggested that homeowners double up by making maximum use of their ovens.Next time you bake a cake or casserole, stick in a vegetable dish, too, said Ms Loustalot.Youll spend less time cooking and more time eating.The advice comes after it was revealed last week that home and kitchen washing appliances are to be brought under the EUs Ecodesign directive which aims to cut down on energy and water usage.
