The Fisker Karma electric car, developed mainly with your tax money so that a bunch of rich VC’s wouldn’t have to risk any real money, has rolled out with an nominal EPA MPGe of 52 in all electric mode (we will ignore the gasoline engine for this analysis).
Not bad? Unfortunately, it’s a sham. This figure is calculated using the grossly flawed EPA process that substantially underestimates the amount of fossil fuels required to power the electric car. In short, the EPA methodology leaves out, among other things, the conversion efficiency in generating the electricity from fossil fuels in the first place, by assuming perfect conversion of the potential energy in the fuel to electricity, the EPA is actually breaking the 2nd law of thermodynamics. And we all know, only Obama can do that.
So what do we get in the bargain? As with most liberal schemes the truth is far more violent.
In the Clinton administration, the Department of Energy (DOE) created a far superior “well to wheels” MPGe metric that honestly compares the typical fossil fuel use of an electric vs. gasoline car, using real-world power plant efficiencies and fuel mixes to figure out how much fuel is used to produce the electricity that goes into the electric car.
One needs to multiply the EPA MPGe by .365 to get a number that truly compares fossil fuel use of an electric car with a traditional gasoline engine car on an apples to apples basis. In the case of the Fisker ‘Karma’, we get a true MPGe of 19. This makes it worse than even the city rating of a current Ford Explorer.
As Obama says, it’s just math … Or there isn’t a free lunch, on stupid sellers of same.
