Either disingenuous or ignorant, yes.
> Energy storage is not a short or medium term solution.
The primary role of energy storage systems in renewable energy sources is to balance supply and demand. Your assertion makes no sense because it ignores even the most fundamental aspects of the problem domain.
> Pumped hydro is already maxxed out pretty much everywhere it's possible as not all dams are suitable -- in fact most aren't. Battery storage for large grids currently covers minutes of use, a few hours may be attainable. But wind can be absent for days or weeks, and there's such a thing as winter when you're as far from the equator as Germany.
Irrelevant. You're trying to put up a strawman based on a fictitious scenario where energy production comes from a single source: wind. It's the tired old meme from two decades ago.
Meanwhile, back in the real world not only are power grids distributed at a continental level but there also multiple sources of power feeding into that grid, including imported energy generated from renewable sources.
