Only use the washing machine when you have collected a full load. If you must wash a partial load, use the economy or half load setting. Also, modern washers work just as effectively at 40 degrees Centigrade (100 F) as they do at 60 (140 F), but the reduced temperature will make a difference in terms of energy used.Tumble dryers use up a huge amount of energy. If possible, hang your clothes on a line instead. This is better for your clothes as well.Washing economically doesnt just apply to your clothes. Taking a shower instead of a bath uses around 50 percent less energy.
