Presenting just a few days after publication of the IPCC Sixth Assessment, Mitigation report, Michael Grubb will summarise research on the economics of innovation and transition and its implications for energy and climate policy. Whilst touching upon themes from the IPCC Mitigation Assessment, the talk will highlight features of such economic thinking in the context of the converging crises of international energy supplies, global COVID-related debt and recovery, and the growing climate crisis. Ultimately, the talk will aim to inform the modern energy policy implications of the old saying: never waste a crisis.
