Low-tech Magazine: Electric Velomobiles: as Fast and Comfortable as Automobiles, but 80 times more Efficient
The guy writes many interesting articles, well documented. On the Dutch version (he's from the Dutch speaking part of Belgium) he recently wrote an article about a life cycle analysis of an electric vehicle compared to conventional vehicle with IC engine, as done by a Norwegian university. So it's written in Dutch, hopefully that will soon appear in english too, or you must ask your computer to translate...This is the link:
