The Model 3 2170 cell is reportedly around ~250 Wh/kg and the pack itself comes in at 160 Wh/kg What if Elon has some new battery chemistry for the 2170 that has similar energy density but say twice the life and at half the cost ? You won't even recognise such a world !

"What is difference between microgrid and solar?" MIcrogrids by definition can island (go off-grid at will) This means they need electrical storage of sorts Solar is typically grid-tied - this means the PVs don't work when there is no grid supply But say NO to

What does a
