Ohhhhh! So this means George Bush was wrong when he said full implementation of
electric cars in the future will reduce auto related polution drastically.

Actually, Bush (and environmentalists) ARE wrong about that. Yasee,
electricity comes from dirty coal-burning plants. Most of the energy
from the coal gets lost in the air or water as heat. Then more of it
gets lost heating transmission lines that bring electricity to your car.
Then more is lost converting that to DC, then to chemical energy in yer
battery, then back to electricity and finally to mechanical energy, some
of which is wasted dragging the heavy batteries around. These losses
consume over 90% of the energy in the coal. Infernal g combustion is
far more efficient, loosing only 70% or so.

Reducing emissions of individual cars doesn't help if there are more and
more cars. Ie if you reduce emissions by 50% but have twice as many cars
you're right back where you started from - except that the 2x more
people driving those 2x cars are also farting, taking dumps, heating
their houses, et al. So, all of these "solutions" are really band aids
covering up the real wound.

Oh well, the Yellowstone eruption will take care of it .... (c:
