But in other parts of the country, you may go months without seeing a single car with a plug.
California tops the list, of course, due to state rules that require sales of certain numbers of zero-emission vehicles by the six carmakers with the great sales in the state (Chrysler, Ford, GM, Honda, Nissan, and Toyota).
But after California, there are a few surprises.
Little Normal, Illinois, designated itself "EVtown" and has more than 300 plug-in vehicles in a city of 54,000.
And even regions not necessarily known for being particularly green in their transport--think pickups, not Priuses--are starting to look at their own efforts.
The article on Mother Nature Network notes that eight states recently banded together to form an alliance for joint promotion of plug-in cars on their roads.
In addition to California, the seven other states--all on the East Coast--have all adopted California's stricter emissions rules. They are Connecticut, Maryland, Massachusetts, New York, Rhode Island and Vermont.
But unlike California, their efforts are spotty and in a few cases, relatively meager. Connecticut, for example, let an income-tax incentive for purchase of a plug-in car expire.
Oregon, on the other hand, now has a state Chief Electric Vehicle Officer, Ashley Horvat. And on a practical level, with neighboring Washington, it pioneered the Electric Highway that stretches from the state's southern border through Washington up to the U.S. border with Canada.
The article concludes with this summary: "Oregon’s below-the-radar [electric-car] activism is encouraging. Other states should follow its lead."
What's your state doing to encourage adoption of plug-in electric cars? What should it be doing?
