This paper proposes decarbonizing transportation with an all-electric National Transit Service(NTS). NTS is an all-electric nationwide door-to-door transit service with new infrastructure. This paper shows that building and maintaining new solar-powered transit roadways, stations, and electric vehicles is economically feasible. Low user cost per mile and very low-cost shared rides would foster high ridership. It will show the estimated cost, revenue, and payback time calculations. The features and benefits of each component are reviewed. There are five major issues with our current transportation modes, and this paper discusses how NTS could mitigate each one.
