Given the world resources what is the total combined storage capacity of batteries?
In other words, if you dedicated all the available resources to batteries, how much total storage could you come with AND what is the life span of that system?
I have 4 GC6 batteries in the big boat for a combined capacity of 430AH new. They last about 5 years. On average I really only have about half that power, 215AH available because the batteries are only infrequently fully charged and you don't want to run them down too far. I try to use my heaviest loads when it's windy and/sunny so I'm drawing straight off the wind gen or panels.
I'm assuming real world scaled systems would be similar.
So if we need 4 GC6 batteries for our fairly low energy life style for 2 people, 2 batteries per capita, then we would need about 15 billion batteries every 5 years for Earth's population, or 3 billion GC6 equivalents per year.
Assuming you can do much better on large scale, let's call it 1 billion GC 6 equivelents per year.
How long before we ran out of the capacity to build new batteries?

Your assuming we have enough resources to make those batteries in the first place. I don't know we do,mor dont.
And yes they can be recycled, but at what cost? I'm pretty sure it can't be done forever, but it may be a long time.
I bring it up because it's one of the questions I never see answers. Like what do we do with the old wind turbine in the ocean. How long will they last? What do we do with the old foundations? How will we get enough energy to replace them in the future?
IMHO all these futuristic solutions need to be accounted for in a complete life cycle basis.
Hell, do we have enough energy just to clean up the mess we have already made?
If sea level rises 60 feet and invades NYC and many other locations,made we just going to let all that pollution from the wreckage go into the oceans?

China and US lead way with wind power installations, says global energy reportLast year saw 54.6 gigawatts (GW) of wind capacity installed across the planet, with global installed capacity now standing at almost 487 GW. China installed 23.3 GW of new capacity, a 42.7 percent share of the market. A distant second to China in terms of new capacity was the U.S., where 8.2 GW was installed.
While China, the U.S., Germany and India continued to show a strong appetite for wind, the 54.6 GW of new capacity added in 2016 was still less than the 63.6 GW added in 2015. "Wind power continues to grow in double digits; but we can't expect the industry to set a new record every single year,"
Renewable generation capacity expected to account for most 2016 capacity additions
Once final data are in, EIA expects 24 gigawatts (GW) of new generating capacity to be added to the [US] power grid during 2016. For the third consecutive year, more than half of these additions are renewable technologies, especially wind and solar.

Pumped-storage hydroelectricityPumped storage is the largest-capacity form of grid energy storage available, and, as of 2017, the DOE Global Energy Storage Database reports that PSH accounts for over 96% of all active tracked storage installations worldwide, with a total installed nameplate capacity of over 168 GW.
