Nearly 87 percent of all cars on U.S. roads could be replaced by more sustainable cars, according to a study in Nature Energy.
Bloomberg reports that if that happened, there would be a 60 percent reduction in U.S. gasoline consumption and a 30 percent decrease in greenhouse gas emissions produced by the United States.
But electric car sales are actually declining.
According to the study, only 0.7 percent of vehicles in the country are electric, and electric car sales actually went down by 17 percent between 2014 and 2015.
The study also addressed the belief that electric cars are too expensive to buy and not worth the investment.
The research, however, said that drivers would only have to recharge their cars once per day to power their average travel.
It also says that while electric cars are expensive, the total cost for operating them would be lower than regular cars.
