Abstract
Varying levels of public acceptance of different low-carbon energy technologies can pose a barrier to progress on decarbonizing the electricity grid in the U.S. We developed a survey system that allowed respondents to design their ideal 100% low-carbon mix for 2035 by allocating generation across seven low-carbon technologies. Using data from 532 respondents, we analyzed overall public preferences and how demographics affect technology preferences. Contrary to what is often assumed, we found that approximately 75% of respondents’ ideal portfolios are diverse (5+ technologies), and many included novel technologies, with approximately 90% including CCS or offshore wind. Regression analysis found that demographic factors affect the amount of a technology that a respondent chose to deploy in their portfolio. Demonstrating the public’s willingness to accept a diverse electricity portfolio that includes novel technologies opens the door for energy analysts and energy developers to investigate diverse and creative solutions to achieve electricity decarbonization. Additionally, demographic factors that affect technology preferences create a new layer of consideration for project siting to increase the likelihood of acceptance. Engaging with the public and considering public preferences will be integral to achieving our decarbonization goals.
