Sweden is leading the way in sustainable transportation with its development of e-roads, which allow electric vehicles to charge while driving, reducing range anxiety and supporting the country's goal of reaching net-zero emissions by 2045. E-roads use conductive and inductive charging methods to deliver electricity to moving vehicles, with the first permanent electrified highway being built on the E20 route. Conductive charging requires physical contact with electrified rails or wires, while inductive charging uses electromagnetic fields under the road surface. These e-roads aim to make electric vehicles more practical for deliveries and personal travel by reducing waiting times and battery sizes. The benefits of e-roads include cutting emissions, lowering manufacturing costs, and promoting economic efficiency through job creation and international investment. However, challenges such as high upfront costs, disagreements on technology standards with other countries like Germany and France, and maintenance issues pose obstacles to widespread adoption. Sweden's strategic investment in e-roads on the E20 highway demonstrates its commitment to sustainable transportation and leadership in the transition to electric mobility.
