From "Elon Musk wanted a race"
" Battery prices are falling so fast that EVs may be cheaper, and offer better features, than the average gasoline car within the next five years, according to an analysis we conducted in February. This week, Pierre Andurand, the hedge fund manager who foresaw the 2014 oil crash, warned investors that “After 2020, there is a high risk that electric vehicle penetration will change the oil market forever."

IMO within 5 years the vast majority of two car families will include an EV by 2020. I also believe most homes with solar will be looking at EV's.
