There is a strong and growing consensus that a simultaneously growing and decarbonizing electricity sector is necessary to meet declining greenhouse gas emissions targets. Rallying cries to “electrify everything” have captured the focus of many headlines and policy forums in recent years. However, there are important questions that remain unanswered about the electrify everything movement, including the technical, social, and political feasibility of the approach, as well as the affordability and equitability of implementation. While reducing emissions is paramount in mitigating the negative impacts of the energy system to the environment and human health, it is also critical that changes to energy infrastructure are both socially and politically acceptable, as well as affordable to help ensure an economically vibrant future. These nuanced dynamics are not easily articulated in public forums regarding the goal to electrify everything. A more detailed assessment of the problem might discover a better path forward.
This report, part of the Power Sector and Renewables Research Initiative and Energy Systems Modeling Analytics program at Columbia University’s Center on Global Energy Policy, in conjunction with IdeaSmiths, examines eight recent major US studies on the topic. Six of the studies focus on strategies and pathways to a net-zero energy system and two assess the value of electrification and expanded transmission networks. This work serves to compare their assumptions and results. The authors’ purpose in analyzing the studies was threefold. First, the report explores the degrees of electrification in the United States that might be needed to achieve net-zero pathways as well as where and how electrification could occur under model assumptions. Second, it examines the relative roles of variable generation resources (e.g., wind and solar), energy storage (both short- and long-duration), and firm low-carbon power (e.g., natural gas with carbon capture, nuclear, hydro, and geothermal) in the energy transition to meet increasing levels of clean electricity demand. Finally, the report examines the barriers that could hinder both increased electrification and decarbonization of the pivotal power sector.
By examining and comparing the studies and scenarios within them, the authors were able to identify shared themes resulting in robust insights that can be useful in informing policy makers and guiding other decision-making processes. Broad recommendations across studies include: (1) decarbonizing electricity; (2) electrifying end uses; (3) lowering energy demand; and (4) increasing transmission, distribution, and energy storage infrastructure. Seven major barriers to expanding electrification include challenges around: (1) the pace of transition, (2) technology advancement, (3) infrastructure siting, (4) equipment cost, (5) supply chains, (6) human capital/jobs, and (7) public support.
To attain the various decarbonization goals analyzed in these studies, federal, state, and/or local regulators would need to implement an array of policies to accelerate the pace at which clean energy technologies are deployed. While the studies generally do not compare specific policies but rather the least-cost path(s) to achieving certain decarbonization targets, none of their reference scenarios indicate the energy sector will decarbonize fast enough to meet emissions targets without additional policies.
Other key findings regarding the potential for electrification in the United States drawn from the eight studies include the following:
All of the studies examined in this report were completed prior to passage of the Inflation Reduction Act of 2022 (IRA). The IRA might shift the cost burden for different decarbonization solutions, but it does not invalidate the findings of the studies. While the IRA makes significant progress in addressing many challenges related to decarbonization, additional electrification hurdles will need to be overcome on the path to net-zero carbon emissions, as highlighted in this report.
