Replace airlines with high-speed rail, interstate trucking with cargo rail, urban car use with trolleys, subways and light rail, suburban cars with light rail and buses, rural cars with passenger trains.

The good news is that all those changes can be made with minimal disruptions and the expected schedules and capacities are easily accommodated once the systems are changed over. The other good news is that all those systems can be run on diesel fuel, which was originally a vegetable oil. The alternative supply line should lend increased stability.

The other good news is that all those modalities are inherently more efficient, no matter the energy source used, than what we have now. A two-fer in benefit because many of the engines replaced are gasoline.

But there will still be economic pressures to shift from distant sources to more local sources. Flying celery in from Spain, or flowers from the Netherlands, only makes sense with cheap fuel. A shift toward more local and seasonal food and materials, likely energy sources, seems inevitable.

Information and data will remain international, being virtual makes transport efficient and fast. Material good and energy are harder to shift. Power-line losses are high so there may be a shift to local small power production.

The problem with solar, wind and hydroelectric power is they are seldom near population centers that are the main users. Biomass and waste-steam, garbage and sewage, methane production are all promising for urban and suburban power production because the resource materials are much more coincidental with the need.
