In 1990, the mandatory standard saved 3.2 quadrillion kilowatts of energy. A further change was made in 2004 to save 6 quads of electricity. The current standard will generate more savings. This results in a 3.3 quadrillion electricity savings for water heaters purchased between 2015 and 2044.
It is estimated that homeowners and property owners can save around $63 billion on their energy bills and reduce carbon dioxide emissions by 172.5 millions metric tons. This amount is equal to nearly 40 million cars’ greenhouse gas emissions.
