The secret to highly efficient dishwashers is electronics. Sensors can measure the weight of the dishes and the clarity of the water (to determine how dirty the dishes are), then determine how hot the water must be to clean those dishes.

waterwiseeducation.org. An excellent site for specific information on water savings developed by the California Urban Water Conservation Council under a cooperative agreement with the U.S. Environmental Protection Agency. You can access this by Googling H20use.
Saving resources as your clothes spin at high speed

A new washing machine will appear in stores this summer that spins clothes so fast (1,200 revolutions per minute) they come out almost dry.

How low can it flow? Water savings with low-flow shower heads add up when the flow slows to a rate of 1.5 to 2 gallons per minute.
Let us count the numerous ways that toilets can flush

How lush does it flush? The newest high-efficiency toilets use only 1.28 gallons of water. Not lush. And that's the point. While 1.6 gallons per flush still is the standard, the new versions use 20 percent less water. The Environmental Protection Agency's voluntary WaterSense program, begun in 2006, will certify that products use less water.
