About
An open database of renewable electricity that never reached a customer — curtailed, spilled, or constrained-off. Sourced from grid operators and regulators. Updated every few hours.

The book
Every Last Joule: How Bitcoin Meets Energy Where It Is — forthcoming. The book's claim is arithmetic: wasted energy already exists at a scale that matters to Bitcoin, and Bitcoin can take it where it sits.

The dashboard
Source is on GitHub: honeybeesquad/every-last-joule-dashboard. Methodology is on this site. Assumptions live in the loaders. Corrections welcome.
Treat the totals as a lower bound. Operators do not publish self-curtailment, and we do not invent it.
Each region's loader, calibration rate, seasonal multiplier, and fallback are in source. Rates are anchored to a 2024 figure from the relevant operator or regulator, cited on the methodology page. If a live upstream fails, a committed last-good snapshot is served and the tooltip badge switches from live to cached.
