Washing machines
Washing machines sold in the UK are required by law to carry the European Energy Label, which rates their efficiency in energy use. Greener energy efficient machines are are cheaper to run, as you save money through reduced electricity bills. If buying a new one, compare brands carefully on sust-it.net and find the most energy efficient model. Ask the salespeople and study the manufacturer’s literature and website. The Which? Reports from the Consumers Association will contain some information though they do not focus specifically on environmental aspects, while Ethical Consumer includes the environment among its assessment criteria and published a buyers’ guide on washing machines in 2003.
Depending on the source of your hot water it may be more efficient to use awashing machine with a hot fill function. These use hot water from your domestic supply rather than heating it by electricity themselves. If your washing machine is a long way from the hot water supply cold water from the pipes will enter it and need heating anyway. Some heat will also be lost from the hot water in the pipes. Energy and water consumption will depend on the programme – a full load on a hot setting will use more water and energy than a half load on a cooler setting. Go for ones which combine energy-efficiency with water-efficiency and look out for energy and water saving features. Modern machines use less water than older ones and modern washing products are designed to be effective at much lower temperatures, so less water needs heating and only to a lower temperature. Try washing your clothes at lower temperatures – it will save energy and your clothes may get just as clean.
