For example, coal-fired power plants that use once-through water cooling systems require more than 27 gallons of water per kilowatt-hour of electricity generated and nuclear power plants draw more than 31 gallons to produce the same amount of energy. Power companies contest that using this water is not an issue because they return most of it to the river from which it is drawn, but putting it back into the water body at a higher temperature leads to increased evaporation and harmful effects for cold-blooded aquatic species. Furthermore, the fact that they need this much water to cool their plants in Southern Georgia and Alabama means that less is available to individuals and businesses upstream, including Atlanta residents.
Embedded water refers to the water used to produce a specific good. For example, a typical cow raised for slaughter will consume more than 2,850 lbs of grain and 15,800 lbs of roughages in its lifetime. Over 810,000 gallons of water is needed to water that amount of crops. The same cow will drink more than 6,330 gallons of water and require an additional 1,850 gallons of water for servicing. Since an average cow will yield about 440 lbs of beef, we can estimate that there is more than 630 gallons of water in one 1/3 lb hamburger patty.
