The COVID-19 pandemic spurred a global cessation of travel, manufacturing, and countless economic activities. This calls for clean energy innovations with immediate responses to the changes and, at the same time, to stimulate innovation for accelerating future sustainable energy transition.

While dealing with the COVID-19 pandemic, the issue of how to combine economic stimulus recovery with green energy transition becomes an important topic for sustainable development in the post COVID-19 era. Among various actions, green recovery plans and carbon neutrality targets are given high priority.

In order to have a better understanding of COVID-19's impacts on the energy transition, it is important to investigate the changes during the pandemic and post COVID-19 in terms of energy demands (in different sectors and different countries), energy mix (including renewable energy penetration), energy load profile (over different days of the week and different hours of the day), emissions and other aspects.
