EPA Fraud: Chevy Volt, Nissan Leaf Actually Get Only 23, 25 MPG

Let's say you took your gas-guzzling engine out of your car and hooked it up to a generator in your garage. The engine has a fuel efficiency of 15 MPG. That's roughly 25% efficient (a 300 HP engine burns about 1000 HP of gas). You run the engine to generate electricity (let's assume, just for kicks, that the generator hooked up to your car engine is 100% efficient) to charge your Nissan Leaf or Chevy Volt. Guess what the mileage of that Leaf is? The EPA says you will still get 99 MPG overall. But you actually used four gallons, not one, to get that far, thanks to the charging engine's 25% efficiency.

The real efficiency of the Leaf is dependent on the efficiency of the coal power plant: the Leaf gets 25 MPG, not 99. The Chevy Volt gets 23 MPG, not 93.

The EPA is purposely comparing apples to oranges, conveniently hiding the fact that you are simply displacing gasoline usage with coal. The fact that you don't have to directly throw coal into your car doesn't mean you aren't using any. Indeed, the overall efficiency of electric vehicles charged on coal is no better than a car with a spark ignition engine.

And far short of the efficiencies achieved with diesel.

Just in case anyone out there is opining that we should therefore go with "renewable sources" (wind, solar etc.), that will make the available energy problem even worse.

Nature will always get its pound of flesh, and the EPA's intentional misleading of consumers doesn't change the fact that we will be no less dependent on fossil fuel at all -- and may be more so in this case. As it is, without far more nuclear power plants, the combination of using coal with lithium -- the mining of which is one of the dirtiest operations known to man -- may well be environmentally worse than just burning gasoline, and is definitely worse than burning diesel.

The Obama administration should hand out a blue pill with each purchase of the Chevy Volt, so you can smugly drive around in ignorant bliss.
