The Tesla seems to be making a fair amount of press. Being a hot little sports car and being green (electric) has put it in the spotlight.
It could be that I do not totally understand. I can grasp how an electric motor vehicle itself might inherintly be more environmentally friendly than say a gas engine vehicle, but beyond the scope of the vehicle itself, I am not sure how green everything is.
Electricity may be cheaper than gasoline at the moment, but if you did mass produce electric cars that need to be plugged in to recharge, how long before we have a hard time meeting demand for electricity? Production of electricity from what I would guess to be more green solutions, such as hydro, wind, or hydrogen doesn't seem to be growing in leaps and bounds, so could enough electricity be produced to sustain everyone plugging their car in every night. Nuclear in my mind has a bad rap and as I understand it, the largest amount of electricy in America today is produced from coal. Would increased burning of coal to supply more electricity really be green? If you compare the carbon footprint from the production of gasoline and the emissions from the gas powered vehicles to that of burning coal and using electric cars there may be a big difference. I don't know. If there is, lets see that information promoted, rather than just focusing on the electric vehicles themselves.
