Can India come out ahead in an energy squeeze?
The slower the growth, the more sustainable an economy is over the moderately long term.
Energy consumption and the use of complexity tend to rise together.
Too much complexity can lead to collapse.
In general, the most “efficient” economies can be expected to do best.
Over the long term, all economies will collapse.
There have been shifts in which economies get a major share of available energy supplies. Shifting patterns are likely again in the future.
India may come out ahead in an energy squeeze because its warm climate and conservative culture allow its energy consumption per capita to remain low. Continue reading

Fossil Fuel Imports Are Already Constrained
The big question for any fuel is, “Can consumers afford to pay a high enough price to cover all the costs involved in getting the fuel from endpoint to endpoint, at the time it is needed?”
Citizens become very unhappy if the cost of winter heat becomes extremely expensive. They demand subsidies and rebates from the government, in order to keep costs down. This is a sign that prices are too high for the consumer.
Both coal and natural gas are also heavily used in manufacturing. Their prices vary greatly from location to location and from time to time. If coal or natural gas prices rise in a particular location, the cost of manufactured goods from that location will also tend to rise. These higher prices will particularly hurt a manufacturing country, such as Germany, because its manufactured goods will become less competitive in the world marketplace. Continue reading

Our Oil Predicament Explained: Heavy Oil and the Diesel Fuel it Provides Are Key
It has recently become clear to me that heavy oil, which is needed to produce diesel and jet fuel, plays a far more significant role in the world economy than most people understand. We need heavy oil that can be extracted, processed, and transported inexpensively to be able to provide the category of fuels sometimes referred to as Middle Distillates if our modern economy is to continue. A transition to electricity doesn’t work for most heavy equipment that is powered by diesel or jet fuel.
A major concern is that the physics of our self-organizing economy plays an important role in determining what actually happens. Leaders may think that they are in charge, but their power to change the way the overall system works, in the chosen direction, is quite limited. The physics of the system tends to keep oil prices lower than heavy oil producers would prefer. It tends to cause debt bubbles to collapse. It tends to squeeze out “inefficient” uses of oil from the system in ways we wouldn’t expect. In the future, the physics of the system may keep parts of the world economy operating while other inefficient pieces get squeezed out. Continue reading
The World Economy Is Becoming Unglued; Models Miss Real-World Behavior
A common belief is that if the world does not have adequate energy, the result will be high prices. These high prices will allow more fossil fuels to be extracted or will allow renewables to substitute for fossil fuels.
In my view, the real issue is quite different: Inadequate energy supply of the types the economy requires can be expected to affect the economy in a way that causes it to become “unglued.” The economy will gradually fall apart as infighting becomes more of a problem. Goods won’t necessarily be high-priced; many simply won’t be available at any price. Political parties will fragment. Conflict within countries, such as the recent Wagner conflict with the military leadership in Russia, will become more common. Continue reading
Models Hide the Shortcomings of Wind and Solar
A major reason for the growth in the use of renewable energy is the fact that if a person looks at them narrowly enough–such as by using a model–wind and solar look to be useful. They don’t burn fossil fuels, so it appears that they might be helpful to the environment.
As I analyze the situation, I have reached the conclusion that energy modeling misses important points. I believe that profitability signals are much more important. In this post, I discuss some associated issues. Continue reading
