The U.S. school bus fleet is more than just a reliable way to transport the nations children to and from school each day. It's the nation's largest public transportation fleet at two and a half times the number of vehicles of all other forms of mass transportation combined. Gifted $100 million over five years, the World Resources Institute (WRI) will use a portion of this to work with a broad set of stakeholders to spur the electrification of over 450,000 school buses. Erika Myers, global senior manager with WRI, joined us and shared more details on this effort, as well as how it will affect the electric vehicle charging infrastructure nationwide.
