Abstract

We use data from two decades of experience with renewable portfolio standards (RPS) in the United States to identify economic incentives which affect states' decisions to adopt RPS, how renewable goals are set, and how states increase these goals over time. We find that income, economic sensitivity to electricity price, and the prevalence of merchant generators influence RPS policy. We also find that the development of in-state renewable resources is an important objective of RPS policy. These factors have led to a divergence in RPS policy among states, with some states pursuing ambitious goals at increasing marginal cost. This suggests that voluntary state support for renewables is not a sustainable approach to increasing the national production of renewables energy.
可再生能源投资组合标准的过去、现在和未来
我们使用来自美国可再生能源投资组合标准(RPS)二十年经验的数据来确定影响各州采用RPS决策的经济激励因素,如何设定可再生能源目标,以及各州如何随着时间的推移增加这些目标。我们发现,收入、经济对电价的敏感性以及商业发电商的普及都会影响RPS政策。我们还发现,州内可再生资源的开发是RPS政策的一个重要目标。这些因素导致各州在RPS政策上存在分歧,一些州以不断增加的边际成本追求雄心勃勃的目标。这表明,国家对可再生能源的自愿支持并不是增加国家可再生能源产量的可持续途径。
