Will wonders never cease in cleantech communication?
GM announced today that the EPA has given the GM Volt a MPG rating on the city cycle of 230 miles. Sounds great, right?
The problem is that anytime you try to get to "miles per gallon" using vehicles that don't necessary use "gallons" you end up in a very strange debate with very strange outcomes.
Rational people can argue that to determine the MPG equivalent of an electric vehicle you simply take the energy equivalent of a gallon of gas (33.7 kWh) and determine how far the electric vehicle would go on that energy. A fairer way to measure this is to count energy coming out of the source, since there are losses in the charging process (forget for a minute losses during transmission and the whole issue of how electricity is generated)
