In Summary, The Tesla Model S Is A Dirty Car
No. The fact is if you have solar power utility installed (independent of owning a tesla), truth is the solar energy generated is a constant per day. The utility doesn't generate more energy when you buy a tesla. So if energy generated per day is 100% and your house is using 60%(just an arbitrary percentage) of it, then 40% of the energy is sent back to the grid. Now with a tesla. this 40% is no longer available to the grid to save some CO2 emissions and you may even draw some energy from the grid. In other words, even with solar power tesla is not saving any CO2 emissions. The author 's argument would be false if only the user has installed a solar power utility unconnected with electricity grid (this is not a wise choice since this utility can't contribute to the grid even if excessive energy is generated) and it's used solely for the tesla. Then buying a pure EV would have a huge positive impact on CO2 emission.
