When confronted with energy price explosions and the climate crisis, the EU cannot waste time and money on castles in the air. Instead of betting on unproven solutions far from market introduction, such as small modular reactors and the broad deployment of all kinds of carbon removal technologies, the EU should build on what works right now. Renewable energy sources have proven to be by far the most relevant and reliable solution. In our new 100% Renewable Action Plan for the next European Commission, the Heinrich-Böll-Stiftung European Union and Environmental Action Germany (Deutsche Umwelthilfe) describe what needs to happen after the 2024 European elections to harvest the benefits of renewables.
