By Preston Howard: The Maximum Power Principle and Why It Underscores the Certainty of Human Extinction in the Near Future
Today’s guest post by Preston Howard discusses an issue central to our overshoot predicament that is often ignored: The Maximum Power Principle (MPP). The MPP states that life optimizes for maximize power, not maximum efficiency, and implies that life does not look forward in time to consider the consequences of maximizing power today.
While preparing an initial report for Florida’s first Area of Critical State Concern1 in 1972, I had the immense good fortune to spend time with Howard T. Odum, an environmental engineering scientist who directed the Wetlands Center at the University of Florida. The area of state concern was the Big Cypress Preserve adjacent to the Florida Everglades. Dr Odum and several of his graduate students had ongoing studies in the area. In informal conversations, Dr Odum explained the Maximum Power Principle as described below. I believe it presents Humanity’s current situation better than anything I have seen about global warming, overshoot, or climate collapse. However, to my knowledge no one has mentioned it in any serious article except Gail Tverberg in her articles about resource consumption.
To understand the Maximum Power Principle2, let us imagine a square island, barren of any vegetation. As happened many times in Florida, suppose our island was created by fill where a shipping channel had been deepened. Situated close to the seaport, someone intended to build something on the new island, but permitting requirements and other administrative delays where taking “forever.” (These details provide a “context” for the discussion.)
The barren island does not remain barren for long, as plants soon begin to grow on it. The solar energy that bathes the island provides abundant energy for the early pioneer plants…
