If you read my comment and understood it fully, you'd notice that in most states, a pure electric vehicle is NOT "about as good as a hybrid vehicle", but cleaner than the cleanest hybrid. Electric vehicles are also getting cleaner with the electric grid while non-plugin hybrids have made no progress in over a decade.

Keep in mind that producing one gallon of gasoline uses more electricity than it takes to drive the same distance in an electric car as that gallon would take you in a gas car.
