Cutting the cost

Most of a wash's energy goes into heating water, so choose a cold or cool cycle for everyday loads; modern detergents cope fine. Run full loads rather than half-empty ones, use the eco setting, and let a high spin speed wring out more water so the dryer has less to do. Front-loaders generally use less water and power than top-loaders for the same wash.
