Energy mix persistence is a defining characteristic of energy systems, for reasons including the long‐lived nature of energy infrastructure and the role of local endowments. This persistence is evident in current energy‐type use being strongly influenced by past use. Our analysis uses data for eight energy types and a large sample of countries, finding varying degrees of energy mix persistence. We also find evidence that carbon pricing appears to have played a key role in tilting energy mixes from coal towards renewable energy. Our estimates provide empirical support to policymakers seeking to implement carbon pricing to transition their energy systems in a lower‐carbon direction.

能源结构的持久性和碳定价的影响

能源混合的持久性是能源系统的一个决定性特征，原因包括能源基础设施的长期性和地方end赋的作用。这种持久性在当前能源类型的使用受到过去使用的强烈影响时很明显。我们的分析使用了八种能源类型和大量国家/地区的数据，发现了不同程度的能源混合持久性。我们还发现有证据表明，碳定价似乎在将能源结构从煤炭转向可再生能源方面发挥了关键作用。我们的估算为寻求实施碳价以向低碳方向转变其能源系统的政策制定者提供了经验支持。
