Nigel Grier is a systems thinker, writer, and founder operating at the intersection of ecological engineering, energy efficiency, and post-carbon economics. Grounded in lawful design and measured restraint, he explores ways to build economic frameworks that conserve rather than consume the biosphere. Creator of the Negawatt Economy, Nigel leads the Grier Group portfolio—including Grier & Associates, Ecological Engineering, Negawatt Labs, and Archetype Intelligence—developing practical infrastructure, strategic intelligence, and regenerative economic tools. His work, published across Modern Diplomacy, Substack, and Medium, combines science, law, and sustainability to guide systems in transition.
