Opponents point out that unlike areas in other countries, mass transit is only economic viable in areas with sufficient density and that on a large scale, massive public transit programs have no chance of becoming self-sufficient.

FORBES: Which Candidate's Energy Plan is Better for America?

Our ability to store electricity in batteries is improving, but current low energy density makes batteries an inefficient choice for large-scale storage.
