Coulomb Technologies Electricity Cost Estimate

The company, which makes electric vehicle charging stations, estimates the cost of electricity at about half the cost of the equivalent amount of gasoline, which is the most reasonable estimate I've yet seen.

There weren't any further details, but if you remember, based on my calculation of gasoline at $3/gallon, my own electric bill and assumed electric propulsion efficiency of twice gasoline propulsion, electricity is about 1/3 the price of gasoline.

Having said that, I am a staunch supporter of electric cars and I am convinced it is the way of the future. But a reality check is that claims that some parties have made that you can drive 40 miles for a dime or two are greatly exaggerated.
