Electrification Could Cut Global Energy Use in Half

Professor Jan Rosenow discusses how global electrification could cut total energy demand in half by addressing the "hidden 80%" of energy use currently dominated by fossil fuels in mobility and heating sectors, where the current system wastes two-thirds of energy as heat. The conversation explores key transition challenges including grid capacity, battery material recycling (where 95-97% can be reused), and China's rapid solar adoption, while emphasizing that electrification now serves as a critical lever for energy security and economic resilience beyond climate concerns.
