This would be more convincing were there some reason to imagine that the electricity to do it were to become easily available.
These sorts of pieces do the credulous a monstrous disservice, although probably often all unintentionally. There will surely be various dodges to prolong the era of whimsical and dilettante travel, but whether quickly or slowly, the palpable cost of travel will have to come back closer to line with the energy cost to accomplish it.
Part of the answer is electric communication, which accomplishes more for less. Part may be public transport, which is far more efficient in people per energy and a lot of other measures. But at some point, perhaps fairly quickly, we will be choosing between the grain for alcohol or the oilcrop for an internal combustion engine and the resources for food. And then the word "horsepower" will regain something of its original sense, however much horses are or are not part of such a system.
We must begin to accommodate a vast reduction in our reliance on transport. on most energy consumption, and on hydrocarbons in particular. This will take an extensive restructuring of society in general and its systems of production and distribution in particular. The difficulties of personal travel are apt to be minor in comparison with the business of getting food, sometimes water, and in many places heat for housing.
How stark all this becomes likely depends on how quickly it unfolds and how early people recognize a solution. At the moment, though, business and government show almost no interest in resolving or helping anything at all, and every interest in skimming power and profit off of emergency.
If history repeats or rhymes, the poor and the majority will suffer intensely and likely long before the wealthy and powerful are sufficiently hurt or threatened to do anything constructive. And the odds that the "cure" is worse than the disease are high.
However, there really are things that can be done, or at least could be done, were someone to decide that they were worth doing. In few cases is there any special need for food or water to come from many miles away. The example of the people of Cuba, who converted much of Havana and the island to gardens upon the fall of the Soviet Union and the tightening of the American siege.
But there is no guarantee that the owners of the US will grant people such access as quickly, and many areas in the US have considerable problems with cold and drought that have little to do with Cuba. There is a lot of warning and some pre-existing examples, but so far still only a small percentage of people who appear to take an interest in how to respond after the wrong decisions have (almost inevitably) been made by the ruling classes.
What can and has to be done is not so very complicated except for this matter of orienting people And after that, it does take some time before things are producing. It might be better to work on solutions first, and stage the catastrophe later.
