A Depression Trajectory

As a sort of follow-up to yesterday's post, we will muse a bit on how much world GDP decline to expect to this Depression.

One assumption that we are making is that over the next twenty years or so, fossil fuels will become too expensive to use very much as... well, fuel. The world is not going to run out of oil, gas, or high quality coal - but their fuel use will mostly be limited to its highest ends (i.e., not for mass private cars, heat, or electricity). In the post-fuel hydrocarbon era, much of the remaining supply will be used for non-fuel uses such as fertiliser, plastics, and specialty chemicals.

Its a rather uncertain thing modelling collapse, but it is not unreasonable to say that hydrocarbon production may decline 90% or so in the next 20 years. That may seem outrageous, but many people like ourselves who make a study of this matter are arriving at similar conclusions. Consider this recent post at The Oil Drum. It's a bit technical, but Figure 3 is worth a thousand words.

As every schoolchild knows, or at least ought to know, the industrial economy grows or shrinks with the supply of fuel. If fuel production declines 90%, the economy will fall by a similar amount. There will be efficiency, nuclear power, solar power, hydropower, and many other ways to mitigate the loss of energy available to society - hopefully enough to keep things civilised. And once Civilisation has weaned itself off fossil fuel, economic growth just may well resume from a new, low base and at a slower rate.

We believe an energy-intensive economy such as the USA's will experience roughly a 90% decline over the next 20 years. At the end of the Depression, per-capita income is likely to be in the neighborhood of $5,000 a year in current dollars.

We suggest the Reader consider what life might be like for them on such an income, or a bit more or less - depending on their skill level. Also to consider what sort of means they would have to produce any income in a world where most people can afford very little beyond the basics of food and shelter.

It will be very difficult to hope that investment capital will produce much income. Which industries will even survive this depression? Virtually all bonds are sure to default, including government ones - either directly or through inflation. Successful investors will likely be the active, hands-on sort.

To earn income will require being involved with a surviving industry, such as agriculture. Otherwise you will need to become entrepreneurial, and hard-working. Though challenging, the changes ahead are manageable - as long as you keep a positive outlook.
