She said the one very important point at the end: << Estimates show that the world is going to need 300 terawatt-hours of battery cell production in order to transition fully to a sustainable future. That is an obscene figure. >>
This is a obscenely huge amount of battery cells. This is why the world needs to develop other ways to store and release energy on demand. Today 95% of the long-term energy storage is pumped hydro storage, so it will continue to play a large part in the future. The other form of energy storage is hydrogen because it may take the place of natural gas in many applications, especially in transportation.
