Electricity Load Implications of Space Heating Decarbonization Pathways

Joule, 2020
Summary We investigate implications of building space heating decarbonization pathways across the climate-diverse United States. We compute that an “all-electric” approach could require a 70% increase in nationwide electricity system capacity.
