China and the world's electric dreams

Electric vehicles sound like the perfect solution to a host of problems facing the world - global warming, air pollution and dwindling fossil fuel supplies.

And as the United States pulls back from the Paris climate accord, many other countries have moved to embrace EVs, seeing them as a future necessity.

Britain plans to ban sales of new gas and diesel vehicles by 2040, India will sell only electric cars by 2030 and oil-giant Norway, where EVs make up the bulk of car sales, aims to phase out fossil fuel-powered vehicles by 2025.
