COVID-19 has caused great challenges to the energy industry. Potential new practices and social forms being facilitated by the pandemics are having impacts on energy demand and consumption. Spatial and temporal heterogeneities of impacts appear gradually due to the dynamics of pandemics and mitigation measures. This paper overviews the impacts and challenges of COVID-19 pandemics on energy demand and consumption and highlights energy-related lessons and emerging opportunities. The discussion on energy-related issues is divided into four main sections: emergency situation and its impacts, environmental impacts and stabilising energy demand, recovering energy demand, and lessons and emerging opportunities. The changes in energy requirements are compared and analysed from multiple perspectives according to available data and information. In general, although the overall energy demand declines, the spatial and temporal variations are complicated. The energy intensity has presented apparent changes, the extra energy for COVID-19 fighting is non-negligible for stabilising energy demand, and the energy recovery in different regions presents significant differences. A crucial issue has been to allocate and find energy-related emerging opportunities for the post pandemics. This study could offer a direction in opening new avenues for increasing energy efficiency and promoting energy saving.

COVID-19 给能源行业带来了巨大挑战。大流行病促进的潜在新做法和社会形式正在对能源需求和消费产生影响。由于流行病的动态变化和缓解措施，影响的时空异质性逐渐出现。本文概述了 COVID-19 流行病对能源需求和消费的影响和挑战，并强调了与能源相关的经验教训和新出现的机会。关于能源相关问题的讨论分为四个主要部分：紧急情况及其影响、环境影响和稳定能源需求、恢复能源需求、教训和新机遇。根据现有数据和信息，从多个角度对能源需求的变化进行比较和分析。一般来说，虽然整体能源需求下降，但时空变化复杂。能源强度呈现明显变化，抗击COVID-19额外能源对稳定能源需求不可忽视，不同地区能源回收存在显着差异。一个关键问题是为后流行病分配和寻找与能源相关的新兴机会。这项研究可以为开辟提高能源效率和促进节能的新途径提供方向。不同地区的能量回收存在显着差异。一个关键问题是为后流行病分配和寻找与能源相关的新兴机会。这项研究可以为开辟提高能源效率和促进节能的新途径提供方向。不同地区的能量回收存在显着差异。一个关键问题是为后流行病分配和寻找与能源相关的新兴机会。这项研究可以为开辟提高能源效率和促进节能的新途径提供方向。
