TDW,

On a global basis governments of all stripes are spending money to encourage the roll out of EVs. For countries with no substantial fossil fuel reserves this is a no brainer. For all countries health care issues related to air pollution must also be considered. Air pollution kills millions of people annually and is caused in large measure by vehicular traffic. In 2010 the dollar cost of air pollution was $1.7 trillion US. The figure is doubtless larger now but I'm too lazy to look for it.

Besides the dollar costs of air pollution there are real quality of life issues. In China pollution from coal plants, cars and trucks has rendered the air unfit to breathe in many places. China has been slowly reducing coal consumption since 2013 and is now starting the process of converting cars and trucks to EV, PHEV and FCEV technology.
