Hi Esh.
You have no doubt already seen other reports like this but I thought it relevant to your point and probably exposes some of the other factors in converting from fossil fuels to energy storage.
I wonder what the home solar system will look like when the owners of say 6 electric vehicles all want to charge overnight. Looks like more storage facilities to recharge the energy that cars will be using for the next day. Then consider the amount of energy needed to produce that which will need to be stored ready to overnight recharge.
Kind regards, Wack.
