Interesting read. I also did some calculations. I took a 100 mile trip yesterday in my Tesla Model S and noted the energy usage in WH/mile. It averaged 300WH/mile. The car automatically calculates this.
Then I calculated the cost per mile for an average ICE car at the current $2.99/gallon and average miles/gallon of 25, which is well-documented. I used the actual cost of gasoline including subsidies, government programs, defense spending to protect oil interests and corn-Ethanol subsidies. The cost comes out to 15 cents/mile on average to operate an ICE car. That does not include the added cost of DEQ, oil changes, new batteries, air filters, fan belts and engine repair/maintenance. The biggest part of these is the labor, not the parts, and labor is not getting cheaper. $100/hour average currently, unless you have a luxury car and then it might be $200/hour. The average maintenance cost for an ICE car is $99/month. If the average driving annually is 10K miles, then this is another 12 cents a mile bringing the ICE total to 27 cents a mile.
Finally I calculated the same for my Tesla. The average electricity rate nationwide is $0.12/KWH. At 300WH/mile, the cost to operate my Tesla comes out to 3.6 cents/mile. The scheduled maintenance on my Tesla over the last 4 years was $2K, so at 10K miles/year, this is 5 cents/ mile. This brings the total for the electric to 8.6 cents/mile. That is less than 1/3 of what it costs to operate an ICE car. I actually expect to spend $0 for the next 5 years however, which would bring the maintenance cost down to 2.2 cents/mile.
So, the bottom line is that the electric car pollutes 37% of the ICE car when charged from current fossil-fueled power plants (based on my previous white-paper) and the cost to operate it is less than 1/3 of the ICE car, even including maintenance. It is literally a no-brainer.
I have not factored-in the cost of replacing the engine in the ICE car or the battery after 200K+ miles. It is more likely IMO that the electric car will still be on the road long after the ICE car is crushed in the junk yard.
