再生可能エネルギー使用基準（RPS：Renewable Portfolio Standards）

Abstract

Renewable Portfolio Standards (RPS) are an increasingly popular policy mechanism for boosting renewable energy's role in the electric power mix. As of March 2005, 18 states plus the District of Columbia have established such a requirement, with additional states likely to approve an RPS in the next year or two.

To understand this growing force, this report considers the history of RPSs and how they are likely to evolve in the future. Drawing on in-depth interviews with industry stakeholders, we analyze the political drivers behind RPS adoption and consider whether the federal government may act to provide some uniform policy in this arena. We also report on how utilities are crafting their responses to these laws and the role of enforcement policies.
