Between 1950 and 2000, the U.S. population nearly doubled. However, in that same period, public demand for water more than tripled! Americans now use an average of 100 gallons of water each day — enough to fill 1,600 drinking glasses!
A recent government survey showed that at least 36 states are anticipating local, regional, or statewide water shortages by 2013.
Most people realize that hot water uses up energy, but supplying and treating cold water requires a significant amount of energy too. American public water supply and treatment facilities consume about 56 billion kilowatt-hours per year — enough electricity to power more than 5 million homes for an entire year.
If all U.S. households installed water-efficient appliances, the country would save more than 3 trillion gallons of water and more than $18 billion dollars per year!
World electricity demand is expected to double between 2000 and 2030. The greatest increase will occur in the developing world, and the most rapid growth will occur in people's homes.
