What you miss is that your "world saving" batteries DON'T get built without a LOT of energy...that energy is mostly oil. You may save some oil driving the car...but you used just about all...if not all or more...oil making the car...because batteries need a lot of energy to create. Lithium is in limited supply you're NOT going to turn ALL the vehicles into electric.
The point You fail to make is what to do with a few million pounds of Toxic Waste, Spent/worthless batteries? None last forever?? A suggestion, Load them up on elons rocket ships and destroy the universe at the same time as Earth..

My replies are long enough already...I don't list EVERY negative.
You are absolutely correct...they don't last forever...they'll need recycling...which TAKES ENERGY. MORE energy than those batteries will produce.
It's called entropy...most people don't know what it is...and fail to account for it. There is NO "perpetual motion" You CAN'T get MORE energy OUT of a battery than you put in. No matter how efficient a battery is...diesel will beat it out. Pound for pound, dollar for dollar.
As the cost of oil goes up...so will the cost of manufacturing batteries. It's a zero sum reality. EREI - energy return on energy invested.
The REAL solution..the ONLY solution that works...that IS sustainable...isn't going to be popular. The planet has twice as many people as it can carry indefinitely. The current population "runs out of supplies" in the not too distant future. And medicine is trying to PROLONG lives? The POOR included? We used to have wars and disease that would cull half the worlds population here and there. And that was BEFORE oil. A planet with a billion would...even 2 billion. But NOT 9 billion +. Living to be well over 100?
It's a zero sum world out there...there's NOT enough to go around. Right now...
we pump oil as fast as we can...THE REAL REASON FOR FINDING ALTERNATIVE ENERGY SOURCES...they WANT us to cut back...they NEED us to cut back because the population keeps growing ...there is always more demand...and it can't be pumped out any faster. We already pumped out ALL the easy oil. NOW...we MUST pump in the arctic, out in frigid oceans, through 6 miles of water, we MUST frack the OLD wells because the other sources aren't putting out fast enough...to meet the increasing demand.
Oil is used for EVERYTHING. It's the key to modern western civilization. We've reached...peak pumping...not peak oil. The oil is there...but it's thick...like molasses...you can only get it out so fast.
