Jason Bordoff interviews Eric Toone at the Breakthrough Energy Summit in London, focusing on the critical role of energy in global prosperity and the challenges of transitioning to zero-carbon energy sources. They discuss the correlation between energy use and GDP, the intermittency of renewables, and the potential of technologies like nuclear fission, fusion, geothermal, and hydrogen to meet growing energy demands while cutting emissions. The conversation explores the green premium, the difficulties of electrifying everything, the importance of energy storage, and the need for innovation to drive down the cost of clean energy solutions to compete with fossil fuels, particularly in developing nations. They also touch on the role of carbon capture, the future of transportation, and the geopolitical implications of clean energy supply chains.
