re: Does the left really believe we can power the entire country on solar and wind?

Bill Gates thinks we should start subsidizing battery storage, do these people even realize that solar cells last about 20-25 years before needing to be replaced, and the batteries will need to be replaced every 5. We are going to fill so many landfills with batteries and solar cells over the next 50 years of the green movement.

Lead Acid batteries .... maybe ever five years if you don't know how to maintain them or if you let them drain to zero.

Lithium Iron Phosphate ... properly maintained can go ten years or longer.

New technology allows for lead acid recycling and more and more of that is happening these days.

The real problem with Lithium Iron Phosphate (LiFePO, pronounced Liff Poh) is the rarity of some of the ingredients required, particularly triphylite. It's fairly scarce.

Energy Density is the key to all of this when it comes to batteries. Finding a compromise between Energy Density and safety is particularly key. It's basic E=MC2 physics. The more energy you pack into a smaller package the bigger the bomb.
