Electric Vehicle Mileage Fraud
I am glad to see that other sites with more influence than I are focusing attention on the electric vehicle mileage fraud. The Green Explored site writes, via Q&O:
The EPA allows plug in vehicle makers to claim an equivalent miles per gallon (MPG) based on the electricity powering the cars motors being 100% efficient. This implies the electric power is generated at the power station with 100% efficiency, is transmitted and distributed through thousands of miles of lines without any loss, is converted from AC to DC without any loss, and the charge discharge efficiency of the batteries on the vehicle is also 100%. Of course the second law of thermodynamics tells us all of these claims are poppycock and that losses of real energy will occur in each step of the supply chain of getting power to the wheels of a vehicle powered with an electric motor.
Finally! For months I have been writing about this and have started to believe I was crazy. I have written two Forbes pieces on it (here and here) and numerous blog posts, but have failed to get much traction on it, despite what appears to be near-fraudulent science. I wrote
the government wants an equivilent MPG standard for electric cars that goes back to the power plant to estimate that amount of fossil fuels must be burned to create the electricity that fills the batteries of an electric car. The EPA’s methodology is flawed because it assumes perfect conversion of the potential energy in fossil fuels to electricity, an assumption that violates the second law of thermodynamics. The Department of Energy has a better methodology that computes electric vehicle equivalent mileage based on real world power plant efficiencies and fuel mixes, while also taking into account energy used for refining gasoline for traditional cars. Using this better DOE methodology, we get MPGe’s for electric cars that are barely 1/3 of the EPA figures.
The linked articles provide much more detail on the calculations. As a result, when the correct methodology is applied, even in all-electric mode the heavily subsidized Fisker Karma gets just 19 MPG-equivalent.
Do you want to know the biggest energy advantage of electric cars? When you fill them with energy, you don't stand there at the pump watching the cost-meter spin, as you do in a gas station. It's not that the energy cost is lower, it's just better hidden (which is why I suggested the Fisker Karma be renamed the Fisker Bastiat, after the French economist who wrote so eloquently about the seen and unseen in economic analysis). It's why, to my knowledge, no electric car maker has ever put any sort of meter on its charging cables.
