Core Idea

The Principle of Minimum Energy states that systems naturally settle into the configuration requiring the least energy to maintain. Water flows downhill. Electrons occupy the lowest available orbital. Organisations default to the process that requires the least effort. This isn't laziness — it's physics. Any system left to its own devices will find the path of least resistance. In business, the principle explains why customers gravitate toward the easiest option, why employees default to familiar routines, and why markets converge on efficient solutions. The founder's leverage comes from designing systems where the lowest-energy path is also the desired outcome — making the right thing the easy thing.
Section 2

How to See It

Product Design
You're seeing it when users consistently ignore a feature that requires multiple steps while flocking to a simpler alternative. They're following the minimum-energy path, and the product should follow them.
Organisational Behaviour
You're seeing it when a team reverts to old processes despite a new system being "better on paper." The old way requires less energy — fewer new habits, less cognitive load, lower switching cost.
Markets
You're seeing it when a cheaper, simpler product wins market share from a superior but complex competitor. Customers are minimising the total energy — cost, learning curve, switching friction — required to get a job done.
Section 3

How to Use It

Design your product, processes, and incentives so the minimum-energy path leads to the outcome you want. If customers should upgrade, make upgrading easier than staying put. If teams should adopt a new tool, make the new tool require less effort than the old one. Don't fight human nature — channel it.
Decision filter
"What is the lowest-energy path my customer or team will naturally take — and does it lead where I need them to go?"
As a founder
Audit every customer touchpoint and internal workflow for energy barriers. Where people resist or drop off, the energy cost is too high. Reduce friction on the desired path until it becomes the path of least resistance. The best products don't demand behaviour change — they eliminate the need for it.
Section 5

Founders & Leaders

Jeff BezosFounder of Amazon; investor; space entrepreneur
Bezos designed Amazon around the minimum-energy principle for customers. One-click ordering, Prime's removal of shipping decisions, and algorithmic recommendations all reduce the cognitive and transactional energy required to buy. Bezos understood that customers don't want more choices — they want less friction. Every Amazon innovation asks the same question: how do we make the lowest-energy path lead to a purchase? Internally, the "two-pizza team" structure minimises coordination energy. The six-page memo minimises the energy needed to reach shared understanding. For founders, Bezos demonstrates that sustainable competitive advantage often comes from systematically eliminating energy barriers that competitors accept as normal.

Connected Models

Reinforces
Least Effort Principle
The Least Effort Principle describes human behaviour: people choose the option requiring the least work. Minimum energy is the physics; least effort is the psychology. Both predict the same outcome.
Tension
[Activation Energy](/mental-models/activation-energy)
Activation energy is the barrier that prevents a system from reaching its minimum-energy state. Sometimes the desired outcome requires adding energy to overcome an initial hump before the system settles into a better configuration.
Pairs-with
[Inertia](/mental-models/inertia)
Inertia keeps systems in their current state. Minimum energy explains why they settle there. Together, they explain why change is hard: the current state is often already the lowest-energy configuration available.
Section 8

One Key Quote

"The best customer service is if the customer doesn't need to call you, doesn't need to talk to you. It just works."
— [Jeff Bezos](/people/jeff-bezos)
Section 11

Summary & Further Reading

Systems naturally settle into the lowest-energy configuration. In business, this means customers, employees, and markets follow the path of least resistance. The founder's job is to design systems where the minimum-energy path is also the desired outcome.
