What Is Emergy and How Does It Measure National Well-Being?

TL;DR

Emergy is a measure of value that quantifies the energy required to produce goods and services, providing a distinct perspective on well-being beyond monetary metrics. It helps assess sustainability by comparing the ratios of renewable and non-renewable energy sources, highlighting the real wealth derived from environmental resources. This approach enables a deeper understanding of economic systems and international trade imbalances based on energy flows.
