Learning Effects and the Commercialization of New Energy Technologies: The Case of Nuclear Power

TLDR

New energy technologies, particularly nuclear power, are argued to benefit from significant learning externalities during early commercialization that could justify subsidies. The study estimates the magnitude of learning effects present in nuclear power development. The authors analyze how experience reduces construction costs and improves cost‑estimation accuracy, distinguishing between external and internal learning. They find that while learning externalities exist, their value is modest and they have little impact on the rate of commercialization.

Abstract

new energy technologies. Arguiments are offeered that in the earl/v das of comrinercialization significant learning externalities that juistify sutbsidy are present. Using nutclear power as a case studv, this article estimates the learning effects actutall/ present. The efect Qf experience on construction cost and on the accursacv Qf cost estimation is exainined. External learning is separated firom internalized learning about both construction cost and cost estiniation. Finall/' an estimate of the value of both kinids of learning externality is provided. The resullts suiggest learning externalities were present, butt had little effect oni the rate of commercialization.
