by Michael Sivak, Sivak Applied Research The overall advantage of battery electric over gasoline vehicles, in terms of well-to-wheels emissions of greenhouse gases, has been well documented. On the two extremes, coal and oil result in about 176 times the emissions from hydro. Natural gas 87.9 Geothermal 16.5 Natural gas 87.9

Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. A paper describing the work is published in the ACS journal Environmental Science & Technology. other parts of the US and the world could be different.
