|The smog in California has improved, but won't disappear until most cars are electric|
California continues to lead the country in adoption rates for cars that plug in, both battery-electric and plug-in hybrid models.
The state offers numerous local and statewide incentives, and many utility companies reward customers for choosing an electric car over a fossil-fuel powered vehicle.
Combined, it's made for a very electric-car friendly environment, and sales results have reflected that since the first modern electric cars were delivered there in December 2010.
According to the latest report released by non-profit organization Next 10, 5 percent of new-car sales in the state are now electric vehicles.
That figure reflects new cars sold during the first quarter of 2017, and it represents a significant jump since the first report was released nearly a decade ago.
There are some other significant figures included in the report as well.
In 2016, nearly half of all zero-emission vehicles sold in the U.S. were registered in California, and zero-emission vehicle registrations rose 45.5 percent from 2014 to 2015 alone.
The milestone sales figure comes at a time when California continues to battle high emissions in the state.
The transportation sector is responsible for 38.5 percent of all emissions in California.
