Maybe I'll find it again. But according to a recent report, there is enough lithium that's already found to replace every single vehicle in the whole world with a Tesla and still have plenty of lithium left over.

The idea of battery storage is to move completely off of coal, nuclear, etc. and to move to renewables. If there is no way to store energy from wind and solar then they are only good when there is sun or wind.

Of course the future is unclear. But theoretically, the same battery technology being developed for EV's will also help energy storage. Solar panels are at an all time low price and are expected to get even lower. If a cheap way to store solar comes about then solar could be the cheapest way to make electricity. In other words, if there ever is an EV revolution, it could mean a solar revolution as well.

How efficient is decomposing water into H2? This is one of the few chemical storage solutions I could see being practical.
H2 is terribly inefficient. Hydro storage takes up lots of land and returns very little. A better alternative right now would be flywheel storage. But supposedly as EV technology progresses, the technology will be much cheaper and available for other purposes, such as grid storage.

Agreed. There is no perfect answer. I may sound like I'm advocating lithium ion technology for every use imaginable. But in reality, with so much propaganda from every angle, who knows what's best for the environment other than banning vehicular travel altogether.

If only they were cheaper and held more energy. Still, super caps technology is in the same race as lithium ion. Who knows what the next discovery will be. If someone finally figures out a cheap way to manufacture graphene the future could be super capacitor batteries instead of chemical ones.

I know, right? It just goes to show that the economy is not based on what is best for society or the environment. It's based on a market to sell and make money. Most people still think 30mpg is great fuel mileage.

Yes, but what range would that be? I've done several 140 mile daily trips in my Leaf. I drive 70 miles to work, let it charge off L2, then drive back home.
