This study assesses the direct, indirect, and total impacts of political partisanship on state‐level utilities' investment in energy efficiency. This subject is of utmost importance because energy efficiency improvement has become a linchpin in worldwide efforts to combat climate change and other environmental challenges. Analysis of data on 51 electric utilities nested within 31 U.S. states indicates that political partisanship influences utilities' energy efficiency policies. There is strong evidence that electric utilities in states dominated by the Republican Party are less likely to invest in energy efficiency than those in states governed by the Democratic Party. This finding suggests that political partisanship may be shaping the policy and regulatory frameworks put in place by state governments to incentivize or compel the participation of private‐sector entities' in environmental management and/or resource conservation.

政治和企业部门对环境有重大意义的行动：政治党派对美国公用事业能源效率政策的影响

这项研究评估了政治党派关系对州级公用事业在能源效率方面的投资的直接，间接和总体影响。该主题至关重要，因为提高能效已成为全球应对气候变化和其他环境挑战的关键。对嵌套在美国31个州内的51家电力公司的数据进行的分析表明，政治党派关系会影响电力公司的能源效率政策。有强有力的证据表明，与由民主党执政的州相比，在由共和党统治的州中的电力公司投资于能源效率的可能性较小。
