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

When the Economy Gets Squeezed by Too Little Energy
When people forecast ever-rising energy prices, they miss the fact that market fossil fuel prices consider both oil producers and consumers. From the producer’s point of view, the price for oil needs to be high enough that new oil fields can be profitably developed. From the consumer’s point of view, the price of oil needs to be sufficiently low that food and other goods manufactured using oil products are affordable. In practice, oil prices tend to rise and fall, and rise again. On average, they don’t satisfy either the oil producers or the consumers. This dynamic tends to push the economy downward.

Ramping up wind turbines, solar panels and electric vehicles can’t solve our energy problem
Many people believe that installing more wind turbines and solar panels and manufacturing more electric vehicles can solve our energy problem, but I don’t agree with them. These devices, plus the batteries, charging stations, transmission lines and many other structures necessary to make them work represent a high level of complexity.
A relatively low level of complexity, such as the complexity embodied in a new hydroelectric dam, can sometimes be used to solve energy problems, but we cannot expect ever-higher levels of complexity to always be achievable.
According to the anthropologist Joseph Tainter, in his well-known book, The Collapse of Complex Societies, there are diminishing returns to added complexity. In other words, the most beneficial innovations tend to be found first. Later innovations tend to be less helpful. Eventually the energy cost of added complexity becomes too high, relative to the benefit provided. Continue reading
