Electricity-generating rooftop solar cells not only save on planet-warming carbon emissions, they also save a significant amount of water, say a pair of Duke University researchers who have done the math.
A given household may save an average 16,200 gallons of water per year by installing rooftop solar, they found. In some states, like California, this saving can increase to 53,000 gallons, which is equivalent to 60 percent of the average household water use in the U.S.
You won’t see the savings on your home water bill, but they’re still important.
