Recessions, the energy mix and environmental policy

How do severe recessions, such as those brought about by the Global Financial Crisis or the COVID-19 pandemic, affect the composition of energy generation between green and dirty sources? Does creative destruction during recessions result in a sustained greening of the energy mix? The empirical analysis presented in this paper highlights that recessions and crises result in permanent, albeit small, increases in energy efficiency and in the share of renewables in total electricity. These effects are larger, however, when complemented with strong environmental policies – both market-based measures such as taxes on pollutants, trading schemes and feed-in-tariffs, and non-market measures such as emission and fuel standards and R&D investment and subsidies – that incentivise and hasten the transition towards renewable sources of energy.
