There seems to be a consensus that the depletion of fossil fuels will follow a fairly impressive slope. What may need to be looked at more closely, however, is not the “when” but the “what.” Looking at the temporary shortages of the 1970s may give us the impression that the most serious consequence will be lineups at the pump. Fossil-fuel decline, however, will also mean the end of electricity, a far more serious matter.

It is easy to assume that the main issue with fossil-fuel depletion is the problem of what to put in our automobiles. For some, the problem may seem hardly big enough to worry about. The average motorist will have to accept paying far more for gasoline than in earlier times. “So what?” the driver may ask. “The Japanese [or whoever] have been paying far more for decades.” And driving is not only a matter of transportation, it is one of our great passions. The mileage we rack up on our vehicles is breathtaking, and for many the motto is, “I’d rather drive than eat.” We can always assume ― with only the slightest of guilt feelings ― that ecological matters are somebody else’s problem. We are tacitly confident, in other words, that our own problem of fossil fuels can be solved by a job promotion and a raise.

But that view may be totally wrong. A far greater consequence of fossil-fuel depletion could be the effect on the production of electricity. As time goes by, the biggest question of all may be, “Can we even keep the electricity going?” If we end up facing unavoidable world-wide blackouts and brownouts, then the result will be a sudden and catastrophic chain reaction. Fossil fuels and electricity are tightly integrated. We cannot have one without the other. Without fossil fuels, we can produce no (or not much) electricity. Conversely, without electricity, we lack the “nervous system” (a good analogy, since nerves work by ion transfer) to control any equipment that uses fossil fuels.

If all the above is true, then what we should be thinking of is not the familiar slope of fossil-fuel depletion depicted in 20 or 30 major studies, but a figure consisting of a gentle slope that continues for a very few more years and then becomes a steeper curve downward. When fossil fuels are inadequate for maintaining electricity, the further results will be manifold. Fossil-fuel production itself will cease, and so will a great deal else.
