After accounting for emissions during manufacturing, even if you powered an electric car with coal power only, carbon emissions of an electric car are roughly a 25-30 MPG car equivalent.<p>However, those numbers get much better as the electric power generation mix improves (at both the car factory and your garage).  In California, now, an electric car is about equivalent to a 70 MPG car.<p>Note that significant efforts are underway to reduce the carbon-intensiveness of our electricity generation, so these numbers will get better over time.<p><a href="http:&#x2F;&#x2F;shrinkthatfootprint.com&#x2F;electric-cars-green" rel="nofollow">http:&#x2F;&#x2F;shrinkthatfootprint.com&#x2F;electric-cars-green</a>
