“…residential efficiency can account for as much as 550 million metric tons of CO2 equivalent emissions reductions annually by 2050 (equal to the combined electric power emissions of California, Texas, New York, Florida, Illinois, and Virginia in 2016). The next highest single intervention source is electrification of vehicles which would account for approximately 481 metric tons of CO2 equivalent emissions reductions annually.”
“However, even as we slowly begin to recognize the cost effective value of pursuing more energy efficiency, the provision of energy efficiency services to low income families continues to fall short of the need and potential. Struggling families sometimes spend more than 20 percent of their incomes on electricity and heat—far more than the national average of 2.7 percent.”
