FWIW, speaking of efficiency–mass transit is ~33% less efficient than hybrid cars and only 50% more efficient than personal trucks(gas guzzlers).
I’m aware that most Americans are infatuated with inefficient systems and wasting resources but do they really build buses with holes in their tanks?
This recuperating trolley bus seats 200 people and consumes 3 kWh/km. That’s 0.015 kWh/km and person:
If half the US population would travel 10,000 km per year in these trolley buses and the average occupancy was 50% 45 TWh of wind power would be needed. 45 TWh require 17 GW of wind power at 30% capacity factor.
17 GW of additional wind power in 20 years costs about 0.06% of the US-Defense budget.
The best selling car in the US seats 3 people and consumes 14 kWh per km in the city. That’s 4.7 kWh/km and person AND requires imported oil and doesn’t run on homegrown wind power.
