Not to mention misinformation about Tesla's "green" factor
Electric cars are an environmentally efficient means of transportation -- if the electricity powering them is from renewable sources. Just one problem: only 13% of American electricity comes from wind, solar, or hydro-electric production.
Many of Musk's claims about Tesla's environmental friendliness aren't based on hard numbers, but on projected numbers as the United States gradually shifts toward a renewable-dominant electric grid. The result is more than a little misleading, since the completion of such a shift is unequivocally not going to happen during the average lifespan of any car produced today.
When it comes to eco-friendly cars, as with anything else, having the right tool for the job is paramount; for many parts of the country, the right tool simply isn't electric -- yet. In the future? Sure, when the grid catches up. For now? If you live somewhere that uses coal for electric production -- and fully one-third of the nation's electricity is coal-based -- you're better off driving an efficient hybrid.
