Electric, for sure. Sustainable, it depends. How green is my battery?

E-car batteries are crucial to meet the targets of the Paris Agreement, but can also have a high social and environmental toll. Experts warn of the urgency of a sustainable value chain and recommend an innovative solution: e-vehicles connected to buildings and repurposed batteries, to optimize the energy consumption.
