Batteries are nice, but they’re insanely expensive at this scale and ruin the entire point of helping the environment. Carbon emissions from huge batteries are unbelievable.
Comment on U.S. solar will pass wind in 2025 and leave coal in the dust soon after

What batteries exactly? The capacity required is huge.

They can be distributed though. I Install solar, most of the systems we install with batteries end up selling back a significant portion of their charge to the grid (iirc our system wide average is 40% nightly resale)
So not only is each house with a battery not using grid power at night, its powering almost half of an equivalently sized house.
Granted, batteries are still on the expensive side, so these systems aren’t coming enough ( I think we’re at ~10% of our systems have a battery)

A competent government that believes in basic science, would give tax breaks to encourage this.
Mihies@programming.dev 4 days ago
Sure, but even then we don’t have a solution today. It’s all in the fuzzy future.

Yeah, that’s a step in correct direction, but can you guarantee that everybody can be powered 24/7 through renewables/batteries, specially during winter? Unless that’s the case you still need a shit-ton of non-renewable energy that’s coming either from fossil fuels or nuclear. And if you want to avoid (co2) emissions, then you need nuclear to cover everybody, and if you have nuclear then it has to run 100% 24/7. OTOH if you don’t have nuclear, you’ll emit all sort or crap during those periods. And so on. Also, it’s not just that batteries are sort of expensive, they are big. Also you are talking houses, but masses live in apartments where placing solar panels or batteries isn’t possible (at least in quantity).

No one will ever have the idea of simply having more batteries right? It’s all in capacity not quantity, because quantity would be to easy right? Got it.
Mihies@programming.dev 4 days ago
Where do you have TWhs of batteries? As you said, both quantity and capacity matters, when lower capacity you need bigger battery which is harder to put somewhere.

Also not renewable and have short lifetimes, kinda the opposite of what the push for “renewables” is supposed to be about lol.

Are you taking about batteries?
FreedomAdvocate@lemmy.net.au 4 days ago
Yes.
