As I did preorder the Model S I of corse end up discussing with a lot of people about it. Most common argument of other people is, that the enviromental footprint is just as high as with a gas car. My google search only dig out the following article:
In the end the article say that if a gas-car emits 60 to 80 mpg (in the german article the say between 3-4 liters of gas) the Gas car will be just as 'enviromental friendly' as the electric car. For this calculation the take the normal energy mix which you get when you don't get a eco-friendly package.
What I just don't get is, that everywhere it's stated that the electric engine is way more effective than a gas one. That enerergy made in any plant is more enviroment friendly than burning it in the car. The study also shows that the battery inpact on the footprint is only 15% of the vehicle...
so how can it end up right beside my 5 year old prius? wich would burn 4.3l of gas theoretically. For me that just doesn't make sense.. but then they are probably smarter than I am.
Are there any other studies?
What do you guys think?
