7] Conclusion. Modelers and leaders everywhere have had a basic misunderstanding of how the economy operates and what limits we are up against. This misunderstanding has allowed scientists to put together models that are far from the situation we are actually facing.

The economy operates as an integrated whole, just as the body of a human being operates as an integrated whole, rather than a collection of cells of different types. This is something most modelers don’t understand, and their techniques are not equipped to deal with.

The economy is facing many limits simultaneously: too many people, too much pollution, too few fish in the ocean, more difficult to extract fossil fuels and many others. The way these limits play out seems to be the way the models in the 1972 book, The Limits to Growth, suggest: They play out on a combined basis. The real problem is that diminishing returns leads to huge investment needs in many areas simultaneously. One or two of these investment needs could perhaps be handled, but not all of them, all at once.

The approach of modelers, practically everywhere, is to break down a problem into small parts, and assume that each part of the problem can be solved independently. Thus, those concerned about “Peak Oil” have been concerned about running out of oil. Finding substitutes seemed to be important. Those concerned about climate change were convinced that huge amounts of fossil fuels remain to be extracted, even more than the amounts indicated by reserve to production ratios. Their concern was finding substitutes for the huge amount of fossil fuels that they believed remained to be extracted, which could cause climate change.

Politicians could see that there was some sort of huge problem on the horizon, but they didn’t understand what it was. The idea of substituting renewables for fossil fuels seemed to be a solution that would make both Peak Oilers and those concerned about climate change happy. Models based on the substitution of renewables for fossil fuels seemed to please almost everyone. The renewables approach suggested that we have a very long timeframe to deal with, putting the problem off, as long into the future as possible.

Today, we are starting to see that renewables are not able to live up to the promise modelers hoped they would have. Exactly how the situation will play out is not entirely clear, but it looks like we will all have front row seats in finding out.
