Consistent with the increasing environmental interest, the clean energy transition is highly critical to achieving decarbonization targets. Also, energy security has become an important topic under the shadow of the energy crisis,. Accordingly, countries have been trying to stimulate clean energy use to preserve the environment and ensure energy security. So, considering the leading role of economic size and volume of energy use, the study examines the USA to define whether energy transition helps decrease energy security risk (ESR) and curb CO emissions. So, the study applies a disaggregated level analysis by performing quantile-based models for the period from 2001/Q1 through 2022/Q4. The results demonstrate that (i) the energy transition index decreases environmental ESR at higher quantiles and reliability ESR at lower and middle quantiles, whereas it is not beneficial in declining economic and geopolitical ESR; (ii) energy transition curbs CO emissions in building and transport sectors at lower quantiles, whereas it does not help decrease CO emissions in industrial and power sectors; (iii) energy transition is mostly ineffective on ESR, whereas it is highly effective in curbing CO emissions in all sectors except for transport across various quantiles as time passes; (iv) the results differ according to the aggregated and disaggregated levels; (v) the results are consistent across main and alternative models. Hence, the study highlights the dominant effect of energy transition in curbing sectoral CO emissions rather than easing ESR. Accordingly, the study discusses various policy implications for the USA.
与日益增长的环境兴趣相一致，清洁能源转型对于实现脱碳目标至关重要。此外，能源安全已成为能源危机阴影下的一个重要议题。因此，各国一直在努力刺激清洁能源的使用，以保护环境并确保能源安全。因此，考虑到经济规模和能源使用量的主导作用，本研究以美国为研究对象，以确定能源转型是否有助于降低能源安全风险（ESR）并遏制 CO 排放。因此，本研究采用了分解水平分析，通过对 2001 年第一季度至 2022 年第四季度进行基于分位数的模型来进行。结果表明：（i）在较高分位数下，能源转型指数降低了环境 ESR 和可靠性 ESR，而在较低和中等分位数下，能源转型对经济和地缘政治 ESR 没有好处；（ii）能源转型在较低分位数下抑制了建筑和交通部门的 CO 排放，而在工业和电力部门则无助于减少 CO 排放；（iii）能源转型对 ESR 的影响不大，而在所有部门中除了交通部门外，在各个分位数下，随着时间的推移，能源转型在抑制 CO 排放方面非常有效；（iv）结果因聚合和分解水平而异；（v）结果在主要和替代模型中一致。因此，本研究强调了能源转型在抑制部门 CO 排放方面的主导作用，而不是缓解 ESR。因此，本研究为美国讨论了各种政策含义。
