Optimizing whole systems for multiple benefits, not isolated parts for single benefits, can make savings severalfold bigger, yet cheaper, and often with increasing returns. The Integrative Design for Radical Energy Efficiency Learning Hub (https://EfficiencyHub.stanford.edu) shares content from the Extreme Energy Efficiency course with people across the globe—for free—in an easy-to-navigate format that allows users to learn the pillars of integrative design and how they can be applied to achieve vast energy and resource savings in all economic sectors.
