The ongoing adjustment and fluctuation of energy, climate, and economic policies leads to potential policy uncertainty. The potential uncertainty arising from these policies has a wide range of effects on renewable energy technology, leading to changes in investment decisions or consumption patterns. Hence, given the worldwide shift towards sustainable technologies, it is critical to assess how these policy uncertainties will affect renewable power. Given this backdrop, this study delves into the impact of energy policy uncertainty, climate policy uncertainty, economic policy uncertainty, and government effectiveness on renewable energy in the United States. The cross-quantilogram (CQ) methodology is employed by using monthly data from 2002 to 2022. The outcomes reveal that energy policy uncertainty effectively promotes renewable energy in the short run, whereas it serves as a barrier to the adoption of renewables in the long run. Economic policy uncertainty reduces renewable energy consumption in the short run, but it increases in the long run. Moreover, climate policy uncertainty accelerates the transition to low-carbon energy sources. Finally, government effectiveness is a significant supportive element of the energy transition towards renewables.
能源、气候和经济政策的持续调整和波动导致潜在的政策不确定性。这些政策带来的潜在不确定性对可再生能源技术产生了广泛的影响，导致投资决策或消费模式发生变化。因此，鉴于全球向可持续技术的转变，评估这些政策不确定性将如何影响可再生能源至关重要。有鉴于此，本研究探讨了能源政策不确定性、气候政策不确定性、经济政策不确定性和政府效能对美国可再生能源的影响。本研究使用了 2002 年至 2022 年的月度数据，采用交叉分位数（CQ）方法。研究结果表明，能源政策不确定性在短期内有效促进了可再生能源的发展，而在长期内则成为可再生能源采用的障碍。经济政策不确定性在短期内减少了可再生能源的消费，但从长期来看却有所增加。此外，气候政策不确定性加速了向低碳能源的转型。最后，政府效能是能源向可再生能源转型的重要支持因素。
