The document discusses e-highways, which are highways equipped with overhead power lines that allow heavy trucks to receive electricity and operate as electric vehicles. It outlines the objectives of reducing air pollution and fossil fuel usage. It then provides details on research projects in Germany testing the technical feasibility of electrifying truck systems. It also describes a Scania truck that was the first to drive on a two-kilometer electrified highway section, operating as an electric vehicle when overhead but as a hybrid otherwise. The conclusion states that e-highways could reduce fossil fuel emissions by 80-90% and energy consumption by 50% or more.
