Rainy Commute

From this past Monday:

The trip took an hour and fifteen minutes, which is typical. The car used more energy than usual, likely due to the wet roads. My Model S has averaged about 275 Wh/mile for the past six years.

My previous car was a Nissan Maxima and I got about 24 miles/gallon. My commute that morning was 41.4 miles. If we assume $5/gallon, this drive to work would have cost ~$8.60. Tier 1 electricity is currently $0.29/kWh from SoCal Edison, which means it cost me $3.67 or a bit less than half the cost of gasoline. Since I have solar panels and mostly charge at work, it likely cost me less. Of course, that does not include depreciation on my Model S. I will never make up the extra cost of the car with operating savings.
