The Clear Science Staff was just reading Energy-critical elements for sustainable development in the current issue of the MRS Bulletin. Energy-critical elements or ECEs are those thought to be important for emerging energy technologies. Notice the elements chosen: the rare earths (pink), the platinum group metals (blue), metalloids used for solar panels (green), and lithium for batteries.
