A new study by the U.S. Department of Energy found that people who drove an electric car for an average of 10 years were more likely to be satisfied with their life than those who drove a gas car for 20 years or more.
The study looked at more than 4,000 people in 20 countries.
A study in 2017 by the National Bureau of Economic Research found that electric cars were less expensive to drive than gasoline cars, and more fuel efficient than gas-powered vehicles.
Electric vehicles can have an electric motor that can produce as much electricity as 100% of the energy the engine consumes, so the cost of the car is lower.
But it also can be more expensive to maintain.
The researchers found that the average electric car has an electric-car battery life of 10.6 years.
Electric cars are expected to become more expensive as the cost per mile of electric vehicle increases.
The average price of an electric vehicle is $36,000.
According to the U, Energy Department, the average life of an average electric vehicle in the U the U S. is 17.4 years, compared to 20.9 years for gasoline-powered cars.
Electric car drivers are also more likely than those driving gas cars to be in college or retired.
A 2016 study by The Brookings Institution found that Americans who drove electric cars for 20 to 30 years were four times more likely, at about 30 years, to have a college degree.
The Brookings study found that nearly half of electric car owners were white, while about four-fifths were Hispanic.
Another study found similar results.
The research found that an estimated 11% of Americans who owned electric vehicles between 2006 and 2015 were either in college, or retired, compared with 2% of people who owned gas cars.
The American Automobile Association said electric vehicles are the future of the auto industry.
“The electric car represents a new generation of transportation, one that is faster, safer, more fuel-efficient and cleaner than existing vehicles,” the American Automotive Association said in a statement.
“We believe that electric vehicles can help bring down the price of gas and make our economy more competitive.”
