BZZZT !!

Wrong !

A combination of the below (depending upon the urban area).

  1. Subways or Elevated Rapid Rail
  2. Light Rail
  3. Electric Commuter Rail (See Long Island Railroad)
  4. Streetcars/Trams
  5. Electric trolley buses

And personal bicycles/tricycles (some with electric assist) with shoe leather.

Use the roofs of shelters at stops for PV + landfill gas should fill most of the transportation power requirements in most cities.  Add a few wind turbines on the edge of town dedicated to transportation and battery banks (not economic for gtid, but OK for high value transportation).

 I fully agree.My main point is that a new system for transportation should be tied directly to the grid.
