As easy to extract resources become more depleted, it becomes necessary to invest more resources of every type in extraction (for example, manpower, oil, natural gas, fresh water), in order to extract a similar amount of the resource. I have called this the Investment Sinkhole problem.
The need to use greater resources in the process of resource extraction leaves fewer resources available for other purposes. Prices adjust to reflect this out of balance. If there is no substitute available for the resource that is reaching limits, the economy adjusts by contracting to match the amount of resource that is available at an affordable price. Some economists might call the situation “reduced demand at high price”. What the situation looks like, in terms most of us are used to using, is recession or depression.
Part of the confusion is that many people completely miss the fact that there is a close connection between cheap energy supply of the exact type needed (for example, gasoline for cars, diesel for trucks, electricity for many factory applications) and the ability of the world economy to make goods and services.
If the price of energy of the type a particular manufacturer or service provider uses increases (say gasoline or diesel or natural gas or electricity), that manufacturer or service provider in the short term has no choice but to pay the increased price, because there is no substitute for energy of the right type. If the manufacturer or service provider tries to pass these higher costs on to its customers, there is likely to be a cutback in demand, leading to a need for layoffs. Alternatively, with longer lead time, the company may be able to find a way around the problem of increased costs, by using more automation, or by outsourcing production to a country where costs are cheaper. Any of these responses leads to reduced US employment and recessionary impacts.
