Electric motors are so much more efficient than internal combustion engines that they are cleaner overall -- even when accounting for dirty coal plants and transmission losses. See the report Environmental Assessment of Plug-In Hybrid Electric Vehicles by the Natural Resources Defense Council and Electric Power Research Institute.
From the ENVIRONMENTAL ASSESSMENT report (page 2): "The 'well-to-wheels' analysis accounted for emissions from the generation of electricity to charge PHEV batteries and from the production, distribution and consumption of gasoline and diesel motor fuels." This means that the greenhouse gas emissions from coal mining, processing, and transportation are not counted for EVs. The same is true for electric power generated from natural gas and oil (the emissions for drilling, production, and distribution are not counted). This compromises the study and the credibility of the NRDC. The EPRI is a biased source. This casts doubt on the entire study. More important than green house gases are sulfur dioxide (acid rain), mercury (ocean/fish contamiation), and particulate contaminants from coal burning (1/2 of electric power generation. And, this analysis excludes the ecological damage from coal mining (land, forests, habitats, rivers, farmlands).
