Abstract

Policies concerning renewable energy transition are the primary responsibilities of individual states in the United States. This article aims to provide a comprehensive evaluation of state-level renewable energy policies, focusing on identifying key factors driving successful energy transitions and offering actionable insights for policymakers. The research investigates: What are the critical indicators and strategies contributing to an effective renewable energy transition at the state level? To ensure meaningful comparisons, states were selected based on top and bottom performance across various energy parameters, including renewable energy share, solar and wind capacity, electricity costs, and policy adoption (RPS, EERS, and net metering). A rubric, structured around environmental, institutional, social, and techno-economic criteria, was developed to measure policy effectiveness across 15 indicators. Scores for each state were weighted based on their contextual relevance, determined through consultations with energy professionals and the adaptation of existing weighting frameworks. Washington state emerges as the frontrunner, achieving the highest scores for both weighted and unweighted transition performance, closely followed by California. Conversely, Kentucky, Texas, and Florida exhibit the lowest scores. A correlation analysis reveals relationships among performance indicators, such as the impact of stakeholder diversity on energy equity and the link between policy integration and energy demand. This study provides a roadmap for prioritizing renewable policy integration, showing how technology and policy drivers collectively influence the rate of energy transitions. It offers essential insights for shaping state-level renewable energy policies, fostering partnerships, and steering states toward a greener and more resilient energy future.
