Of course their not clean.  It's called "green washing".  Honestly, to make a real "green" vehicle, you'd probably need to spend a LOT more than what they charge.  Mining resources has never been "green", nor is all sources of hydro "clean".  Even hydro dams has issues, mostly due to the materials used and flooding. Solar panel... well they don't really recycle those, let alone windmills made of fiberglass getting buried once "spent".  <br>It's all green washing to maximize profits.  Could it be done better, yes, would they, probably not since it less profitable.
