The 66% Leak

How We Built an Industrial Economy That Throws Away Most of Its Energy - and How to StopEvery year, global industry discards more than 66% of all the energy it produces. It’s paid for, generated, consumed for a moment - and then dumped into the sky through cooling towers, exhaust stacks, and chiller loops. This waste is so normalized that most facilities don’t even see it. But the cost is enormous: higher utility bills, volatile peak demand charges, strained electrical grids, and billions in lost operational value.The 66% Leak exposes the hidden architecture of industrial inefficiency and reveals why modern plants, data centers, hospitals, and manufacturing campuses quietly bleed energy every hour of every day. Drawing on decades of executive leadership in the nonprofit sector, sixteen years in commercial and utility‑scale solar, and real‑world deployments of advanced thermal storage systems, P. Anthony McAnelly delivers a practical, non‑academic guide for decision‑makers who need results - not theory.Inside, readers will discover:Why legacy engineering isolated thermal energy as a 'waste stream' instead of a financial assetHow low‑grade heat became the largest untapped resource in the industrial economyWhy peak demand charges punish facilities for the way they manage heatHow synthetic phase‑change materials and behind‑the‑meter thermal storage redefine what’s possibleHow early adopters are converting waste heat into dispatchable, on‑demand thermal powerWhy thermal sovereignty - not more generation - is the next frontier of industrial resilienceFrom data center deployments recognized by ASHRAE to manufacturing pilots that turn environmental liabilities into revenue‑saving assets, The 66% Leak shows how companies can reclaim wasted energy, flatten their load curves, reduce OPEX, and build true operational independence.This is not a book about theory. It is a blueprint for action - a guide for plant managers, CFOs, sustainability leaders, and executives who are ready to stop the leak, capture the value they already produce, and build a future where every BTU counts.
