Front-loading washing machines use less water and cost less to operate. Using the warm water setting reduces the energy needed to heat water; you can also save energy by only using the machine to do full loads of washing; do not wash one item at a time.
Tumble dryers are high on the list of appliances that consume the most amounts of energy. When shopping for a tumble dryer look for a machine that offers electronic humidity control, as these are the most efficient machines. They automatically shut off the drying cycle when clothes are dry, saving you time and energy and, in the long run, money. Using the correct temperature setting also minimises electricity use. Removing excess water before putting clothes into the tumble dryer saves time and power. But, best and easiest of all, rather use sunny days to dry clothes outdoors.
