Electrification: Its Role in Deeply Decarbonized Energy Systems [Guest Editorial]

The eight articles in this special section provide a snapshot of state-of-the-art research focused on the role of electricity in deeply decarbonized energy systems. Four of the articles take a geographic approach and describe how national or regional electric sectors might evolve in highly decarbonized futures. Two of the articles explore topics that cut across many regions: electrification of heat and market design. The final article summarizes a wide range of recent electrification simulations and proposes principles for advancing the quality of analysis.
