Fw: Electric cars could help cool down our cities

Via CityMetric

I like the concept of electric vehicles avoiding the production of extra heat during Summer. You can read on here. The following vicious circle tends to happen in hot cities:

1. City gets hot (lack of tree cover, building materials that retain heat)
2. Car engines (traffic) produce additional heat
3. Motorists turn on AC to cool themselves, using additional car engine power, and producing additional heat around them.
4. Go to 1.

Electric vehicles reduce 2 and partially 3. There is great potential for compounded benefit. What do you think?
