Tesla 100th Supercharger

In the latest update on energy delivered to Tesla Model S EVs via Superchargers, Tesla Motors states:

"#WattsUp: Superchargers have delivered 5.8 million kWh of energy, offsetting 664,359 gallons of gas."

That would be a global figure, taken from the 114 Supercharger locations worldwide.  This 114 figure includes 94 in the US, 17 in Europe and 3 in China.

If only Tesla provided us with a cumulative global sales figure for the Model S, then we'd be able to calculate, precisely, the kWh energy consumed from Superchargers by each Model S in circulation.  Best estimate is about 36,400 units currently, which would equal 160 kWh, or about 3-4 stops per car based on the average charge amount.
