According to the chart, the author concludes that in most regions such as Ontario and California where most of the electricity comes from wind, water, or other renewable resources, electric cars result in less pollution than the best all-gasoline cars do, whereas in some regions like Alberta where vehicles mainly use electricity derived from combusting coal or natural gas, electric cars create similar impacts on environment as conventional gasoline-based motors do.
