Over the last 2 days I've driven a Model S 800+ miles for business. Almost half of that was done with my own P85, the remainder was done with an S85 loner from Tesla (mine was in for a 2-day service visit).



At my trip's average consumption (312 wH/mile) and my electricity rate at home ($0.12 KWH), the electricity I used to drive those 800+ miles cost about $28. I actually only paid about $5 for that (as the loner was plugged in at my home for just 1 night). The rest of the trip was on Superchargers.



The "fuel" cost of the trip was about $0.036 per mile. I actually only paid about $0.006 per mile (that's .6 cents per mile).



I did patronize the businesses that hosted the Superchargers. I didn't keep track of what I spent at each stop, but over the 800+ miles I bought myself meals, snacks and drinks in excess of the $23 electricity costs the 2 cars drank in electricity.



What can we deduce from this?



The calories needed to keep me going for 800+ miles costs more than the KWHs for the Model S!
