In this episode of The Sound of Economics, Rebecca Christie sits down with Bruegel's Ben McWilliams and Rhodium's Senior Analyst Marie Tamba to talk about the solar energy transition, and how better information on investment and deployment can lead to better policy. Data trends in the EU and the U.S. offer insights into where clean energy is ramping up and what steps will help going forward. They also discuss how a proposed EU-wide energy data agency could help Europe form a clearer picture of where things stand.
