The COVID-19 pandemic might delay a full rebound in world energy demand to 2025, according to the International Energy Agency (IEA) on Tuesday.

The agency said in its World Energy Outlook that global energy demand is predicted to drop by 5 percent in 2020, energy-related CO2 emissions by 7 percent, and energy investment by 18 percent.

In its central scenario, a vaccine and therapeutics could mean the global economy rebounds in 2021 and energy demand recovers by 2023, the IEA said.
