Climate action: an "oasis of diplomacy" for US/China, says Energy Secretary Granholm

China is the world's top emitter of greenhouse gases. Despite a recent chill in ties over Taiwan, President Biden is eager to reengage Beijing on things like clean hydrogen, US Energy Secretary Jennifer Granholm tells Ian Bremmer on GZERO World.

The Biden administration understands that the Europeans need to keep the lights on, says Granholm.
