I'm planning on purchasing an electric car when I replace the car I drive now. After looking into it, I was disappointed to find out that all of us switching to a battery electric cars won't make that big a dent in global greenhouse gas emissions. Cars are responsible for only around 15% of these global GHG emissions (see [1], [2]). Furthermore, a battery electric vehicle produces approximately 180 of grams of CO2 per km (counting life cycle emissions). This is sometimes better than gasoline powered vehicles that produce about 240 g/km. In locations where coal is generating the utility electricity for charging, it turns out that gasoline powered cars do better than battery electric vehicles! (see [3]) The big win happen if you can charge the car on purely renewable energy.
