What if you don't have wind? Sun? Is that also sorted out?
- jacquesm 7y agoI've worked on a number of renewable energy projects and these hold true for any scale. We can make turbines rated > 10 MW now, and solar panel production at scale is a solved problem. We're looking at logistics issues now, not at manufacturing, reliability or basic physics issues. As for why wind does not need batteries: Wind power fluctuates on short time scales, these are not a good match for batteries. There are some interesting solutions to these problems that involve superconducting material (in actual production, not lab level stuff). For solar with a 24 hour cycle batteries are much more important.
