Here's what types of storage we have available and their costs and benefits: https://www.energy.gov/sites/default/files/2019/07/f65/Storage%20Cost%20and%20Performance%20Characterization%20Report_Final.pdf https://www.energy.gov/sites/default/files/2019/07/f65/Stora... Depending on how reliable you need your energy you'll need various energy storage mixes. Judging by the uk, wind can spend an entire month producing at 15% of it's normal output and can spend days at 3%. So you need a LOT of storage if you want to be sure the lights stay on. In the high hundreds of billions of Euros (and considerable ongoing costs given they need the equivalent of replacement eveey 10-20 years) in the case of Germany.

There have been nearly no investment on energy storage in our history (for very obvious reasons). Thus, any such report done with information collected by looking at history is prone to be completely wrong. (And yes, we are going to need a lot of storage. On amounts close to 1/3 of our daily generation capacity. We also need some long-term and transportable solutions. And yes, there are currently no options on the market, for very obvious reasons. All of those can be done.)

  > There have been nearly no investment on energy storage in our history (for very obvious reasons). By "nearly no" do you mean "tens, possibly hundreds of billions"? Batteries alone have had tens of billions in investment in the last few years. > On amounts close to 1/3 of our daily generation capacity. What kind of mix and overproduction are you thinking of that gets you ratios that low without brownouts? I suspect that if you want to live off wind and solar you'll need a week of capacity to get no brownouts when it's still and gray for a week unless you get nameplate capacity 10x your average needs.
