A massive switch to electric cars is not just good news for the environment. It’s good news for your wallet as well. The average driver may save up to $1,700 a year. A study by Cambridge Economics has calculated that electric cars would result in a 40% reduction of oil imports for a country like Great Britain. The positive byproduct of clean air would mean another $1.8 billion saving on annual health care costs. Consumers have been reserved because they cannot charge an electric car everywhere. A better infrastructure, with energy from renewable sources, is, therefore, crucial, say the report’s authors. “There will be a transition in the next five-10 years but you won’t see a sudden shift to electric vehicles until consumers have got over their ‘range anxiety’ concerns, and that will only happen with infrastructure spending.”
