When President Obama first took office, he pledged to help put 1 million electric vehicles on America’s roads by 2015. But with little time left, not much progress has been made – and one of the reasons maybe the expense. According to a survey by the Wall Street Journal, those who do own electric vehicles tend to be the more affluent of society, with nearly a third having incomes of over $200,000 per year. And because of their wealth, electric car owners are content to only use their vehicle as a backup, a luxury many Americans simply can’t afford. With price tags often topping $40,000, it maybe some time before electric cars get widely plugged into average American’s homes.
