I hate to bring you bad news, but if you look at that side, with real data, you'll find that is no better that that low eff ICE.
Here's some reading to help better understand the misconceptions.

Diesel vs. Gasoline
and this one
The Battery Powered Car
The fact is most don't consider or understand the true efficiency of converting that fossil fuel into the power used to change a car battery. They just look at the new power plants and do not consider all the losses between the plant and the battery. By far the majority of generation in the North America is 30 year old low efficiency and dirty emission units. Another detail is fossil fired power generation is king and will be for some time. Cost to build new power generation drive this. Solar and wind are a trivial few now and by all real predictions into the future. |
I considered much more than the 3 to 1 efficiency of the electric motor to ICE. That 4% pollution figure I quoted entails the actual renewable electric generation factor. Another factor lowering that 4% even more is that electricity, KW to HP is delivered to outlets more efficiently than liquid fuels are delivered to gas stations. A 6 pound gallon of fuel mixes with oxygen in the air, causing 19 pounds of carbon dioxide to form plus other pollutants. But considering the fuel NEEDED to transport fuel to gas stations, 1 gallon of fuel actually causes 28 pounds of carbon dioxide plus an equivilent increase in other pollutants.
A factor not considered often in the use of electricity to take over traditional jobs of ICE, is that KW to HP, gasoline tankers are replaced by transmission lines freeing up a bit of our over-congested highways.
AFTER all the above, THEN the 3 to 1 efficiency factor of the electric motor over the ICE comes into play.
May ICE die an economic death in favor of the electric motor that people will live free of the fine & nano particles produced & emitted by ICE. Only now are preliminary but devastating health studies beginning to show the tragic results on human bodies of the smallest particles emitted from ICE.
