Here in the midwest the powerplants still use coal burning plants (and refuse to upgrade to cleaner burning systems) so you are basically still burning fossil fuels to run a vehicle. You have exchanged a multi-point pollution source for a single point pollution source. California which does not generate its own power gets its sources from both clean (hydro... I believe as far as Quebec) and dirty plants (fossil fuel... Texas and possibly nuclear... ie disposal of spent rods). The truth of the matter while these places are trying to clean up their act (the cities mentioned) they are merely transfering the pollution problem to other parts of the country. Very few of the cities mentioned where this is sold produce 100% of their own power. Some clean some dirty. But in either case the are feeding on other parts of the country (as large cities tend to do). If everyone in these cities were to get one of these cars could you imagine the energy production needed. What would happen if close to a million people plugged in their charges (which would likely happen in the evenings as people come home and need to recharge)? What normally be non-peak times for powerplants would then become a 24-hour full output system. I'm still waiting for the Back To The Future Delorian the runs and cleanly generates power using garbage. Now that would be an advancement instead of rehashing old technologies.
