The growth of renewable energy is a hopeful and positive sign for society. It is not merely a fuel switch, however; it is a disruptive technology that is revolutionizing the fundamental economics of the grid itself. As fossil-fuel “storage” is supplanted by intermittent renewable energy, peak load is transitioning from demand-driven to supply-driven, and shifting the focus from “energy” to “power." Load shifting and shaving, demand response, and energy storage will be more critical and valuable than ever before. This presentation explores the untapped value of thermal storage, high performance building shells, and other Passive House principles within the context of this “new grid.”
