How are you charging your Model S or Roadster ? I would like to know how many owners are effectively running their Teslas C02 free.
1- I have my own solar array, it produces xy % of the needed kWh/y
2- i don't have solar, but buy electricity, which comes from 100% renewable sources (solar, hydro, wind, others)
3- i live in an condo and can't chose
4- i buy the cheapest available electricity, no matter where it comes from
I'll make a start:
1: Solar on house and garage, 20kWp, annual production ~*18'000kWh, it is enough for the Model S, the Roadster and the house consumption, the rest is sold to the grid @ CHF 0.42/kWh
