Nicht Pedelec (eFahrrad), nicht Velomobil, beides.

A simple calculation can illustrate this claim. Imagine that all 300 million Americans replace their car with an electric velomobile and all drive to work on the same day. To charge the 288 Wh battery of each of these 300 million eWAW's, we need 86,4 GWh of electricity. This is only 25 % of the electricity produced by existing American wind turbines (on average per day during the period July 2011 to June 2012, source). In other words, we could make a switch to private vehicles operating on 100 % renewable energy, using existent energy plants.

Now imagine that all 300 million Americans replaced their cars with an electric version like the Nissan Leaf, and all drive to work on the same day. To charge the 24 kW battery of each of those 300 million vehicles, we need 7,200 Gwh of electricity. This is 20 times more than what American wind turbines produce today, and 80 times more than what electric velomobiles need. In short: scenario one is realistic, scenario two is not.
