Bidirectional charging also has the potential to make the entire power grid greener and more efficient, enabling increased and better use of wind and solar power. With bidirectional charging, vehicles are also able to discharge power from their batteries, feeding it back into buildings and the grid when plugged in. For one thing, electric vehicles can be driven to locations where extra power is needed during natural disasters and mass evacuations. But electric vehicles could be used to store some of that energy and feed it back to the grid when needed. With bidirectional charging, when vehicles aren't in use, they can sell power back to the grid.
