Here's a link to the article : http://abcnews.go.com/Business/wireStor ... w-51470734
This paragraph caught my interest (I was surprised by the numbers) :
"California buyers purchase a higher percentage of hybrids and electrics than the U.S. as a whole thanks to state tax credits and other incentives. Nearly 50 percent of all U.S. electric vehicle purchases since 2011 have been in California, according to the International Council on Clean Transportation. California also has 31 percent of all U.S. public charging infrastructure for electric vehicles."
