The companies we work with often ask us to translate their water savings into energy and CO2 emission savings. To do so, we use the following ratios, which have been reported by the EPA and DOE, respectively:
1 gallon of water = 4 watt hours of power
1 kWh = 1.34 pounds of CO2
So, 1 million gallons of water conserved prevents the emission of 5,360 pounds of carbon dioxide.
