One more thing about batteries... the supplies of Lithium are finite. ---- And Can be recycled (At Cost)
Windmills and solar won't be able to power the world with the required availability. --- Look at what Musk is doing with On grid Storage. That has the ability to change the game. Store Solar and Wind and use power when needed. With a Nuclear Base power that is the future in my mind. Goodbye coal, Oil and Gas
