The Principle of Least Work is universal in nature. It is a fact in structural response to loads in buildings, ships, planes, cars, trucks, etc. This process happens by doing the least amount of work by most plants and animals. All non-living material and man-made structures also do the least amount of work when responding to loads. They never take a harder way.
Only fossil fuels today and synthetic liquid and gas fuels and nuclear power in the future can provide for a modern world for 8 plus billion people for the long term. Wind and solar are the choices of alarmists who insist on returning the world to the misery before the use of fossil fuels.
