Globally, at the end of 2010, there were 25,000 electric cars on the road. At the end of 2011, there were 80,000 – more than three times that amount. At the end of 2012, there were 200,000 – 2.5 times more. And at the end of 2014, there were 405,000. Translation: the number of EVs sold doubles or triples each year. Meaning: sales are exponential.
