Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Renewables cannot be spun up. You have to massively over build to do that. And even then, you're still depending on availability of sun and wind.

If you need more power than is available, it's done with natural gas peaker plants at 10x the normal cost of electricity.

On the flip side, a stable base load of nuclear, can be spun up and down over the day to meet expected load.

Renewables can effectively be spun up or down as long as they have batteries. That way, they can usually be generating as much energy as possible regardless of demand.

is our battery tech even up to this?

Yes. It costs less and requires less mining to use the most expensive and wasteful storage option. The only reason there aren't more is a lack of sufficient investment in VRE required to make them useful.
