Energy costs.

Last week I was looking through the September 1938 edition of Popular Mechanics and saw a quick cost analysis showing the SAVINGS from using a Ford V8 gasoline engine instead of a comparably sized electric motor. My head nearly exploded because the numbers for my own equipment show that running costs(all inclusive) are 10-11 times greater when the prime mover is an engine rather than an electric motor.

I thought of how cheap the gasoline must have been but the electricity cost in the analysis was $0.03/Kwh. An inflation adjustment would put that around $0.50/kwh today so while fuel was relatively cheap then, not nearly as much as I initially thought.
