This grant provides support for the National Academies of Science, Engineering, and Medicine's (NASEM) to implement a new Forum on Energy Systems Transformation and Decarbonization.  Unlike standard consensus committees, NASEM Forums offer the flexibility to respond quickly to emerging issues related to energy system decarbonization through workshops and other activities. The Forum will host annual public workshops, smaller closed meetings, and produce various outputs, all while providing networking and engagement opportunities for participants. Topics for Forum discussions may include issues like energy innovation, regional impacts of energy transformation, and the behavioral and economic dimensions of energy policies. In each of the next three years, the Forum will host at least one major public workshop and one smaller, closed meeting of Forum members. It will produce a summary workshop report following each public meeting, along with additional digital and print outputs as relevant. Beyond these tangible products, the Forum is designed to provide interactive engagement, networking, and community-building opportunities for the wide range of participants who join these events.
