I guess the biggest bottleneck for renewables is energy storage.
Pretty much. Once we got that covered there is no excuse anymore.
It's basically solved. Sodium batteries are cheaper and much more durable than lithium batteries, and are currently being commercialized. Their only downside is that they are heavier, but that does not matter for grid-scale storage.
Being cheaper than Lithium is great, but are they cheaper than nuclear?
The manpower of maintaining all these batteries seems like it would also be a lot, how would you do it for an entire grid, or would you need to have each individual placing a battery on their property to deal with brownouts?
Problem with coal or nuklear is it isn't cheap. In Germany it survies only on subsidies. And Nuclear was abolished in Germany, a bit to early. I said we needed it 10 years longer and we could have shutdown our coal.
