True, but that's not reliable source of energy though, specially during short and cloudy winter days when it's most needed. Look what happened in Germany and how they became on if the biggest European polluters. The key ingredient missing is energy storage. Once that's solved, solar panels would become much more useful.

We could massively subsidize home battery storage and this wouldn't be an issue at all. Microgrids are the future anyway. The only reason why storage is an issue now is because it needs to be centralized. Once we get away from that tons of new possibilities open up.

[–] mihies@kbin.social 3 points 9 months ago

Home batteries are expensive and take a lot of place. Also they won't last more than a day. Imagine winter time with short cloudy days. Realistically you need at least a month worth of energy storage and even then you need sun to recharge it. They would distribute energy consumption better though by charging during night.

We have all the technology for energy storage we need, it just needs to be built. Theres gravity storage like pumped hydro, pressure storage, thermal storage, flywheels.

[–] mihies@kbin.social 2 points 9 months ago (1 children)

Well, no. Sadly we don't. At least not in the range needed. All of these require either specific geographic relief, something really huge, too expensive or combination. Perhaps the most promising is the green hydrogen, but then again, we have yet to see it at such scale. I'd love to be wrong, though.

[–] blazera@kbin.social 2 points 9 months ago (1 children)

something really huge

yeah, we use a lot of energy, absolutely every form of energy production we have involves really huge things. Massive mines, dams, pipelines, oil rigs, nuclear cooling towers, fossil fuel power plants, oil tankers. They just have to be built. we can excavate dams, build solid weight lifting facilities, molten salt storage, make arrays of flywheels. There's a ton of answers to energy storage already, they dont involve resources with any kind of scarcity, they just have to be built.

[–] Cryophilia@lemmy.world 1 points 9 months ago (1 children)

Big construction involves environmental concerns, that's why we don't have many new dams nowadays

[–] blazera@kbin.social 1 points 9 months ago (1 children)

Boi i better see you raising a fuss over that infrastructure bill

Grrl I don't remember voicing my own opinion on anything
