The World Economic Forum is calling for a global transition from away from private ownership of vehicles and other “idle equipment” in order to make a “clean energy revolution” possible.

In a report published on July 18, the international lobbying group based in Switzerland said that “transition from fossil fuels to renewables will need large supplies of critical metals such as cobalt, lithium, nickel.” But the report noted that shortages of these “critical metals” could make renewable fuel technologies prohibitively expensive.
