A recent delivery of 200 electric buses from Chinese manufacturers BYD and Yutong, with more orders to come, is advancing Chile's goals for electric-powered public transit — 80% by 2022 and 100% by 2040.

Why it matters: Chile is electrifying transportation to help clean its air, reduce urban noise pollution, cut oil imports and add more renewables to its energy mix. Moving toward electric mobility is also a way for Chile to tighten its trade ties with China, the dominant player in the global electric bus market.

The Commerce Department released on Tuesday an interagency report that identifies a list of minerals deemed critical to U.S. strategic interests and outlines an action plan to ensure their supply.

Why it matters: Securing these minerals and their supply chains is essential to leading the way on technologies that will enable the global energy transition, including cobalt and lithium for batteries, graphite and scandium for fuel cells, and indium and tellurium for solar panels.
