After more than four years of modern electric-car sales, it's clear that some areas are more favorable for plug-ins than others.
Whether it's local incentives, available charging infrastructure, or just a cultural climate more attuned to green-car ownership, some parts of the U.S. have embraced electric cars more than others.

So what's the best place in the U.S. for electric cars right now?
Every year, network operator ChargePoint compiles a list of the top 10 U.S. cities for electric cars, based on the number of vehicles registered and available charging stations.

The company only counts stations on its own network, though, and accounts for population differences when comparing the number of car registrations.
Perhaps not surprisingly, one area in California led the way this year, although the Golden State didn't completely dominate the rankings.
That region was the San Francisco Bay Area--which encompasses Oakland and San Jose, as well as the city of San Francisco itself.

While Los Angeles had a higher overall total of registered electric cars at 57,000, ChargePoint said San Francisco's total of 48,000 represented a greater percentage when compared to its population.
This is San Francisco's second year in a row as the top electric-car city; Los Angeles moved up from sixth to second place.
Seattle was bumped down from second to third, directly ahead of San Diego and Honolulu.

They were followed by Austin, Detroit, Atlanta, Denver, and Portland, Oregon.
Atlanta and Denver are new to the top 10 list this year, while Washington, D.C. and Boston--ranked ninth and tenth last year, respectively--fell out of the top 10.
With strong local government support and an established charging infrastructure, the West Coast will likely continue to be the most electric-car-friendly region of the country for the time being.
Yet if more cities undertake similar efforts to promote electric cars, this list could become a little more diverse in the years to come.
