電動車是否比較環保？

用電動車是否比較環保？看看德國的報告吧！不是用電就一定環保，只是污染不在你面前發生。

A worst-case scenario would be that the electric cars would run on electricity from coal instead of from renewable sources.

That could be the case when extra electricity is needed to charge the plug-in cars in the early evening. That's when commuters could significantly add to the electricity demand at a time of day when people are returning home and electricity use is already peaking.
