2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious right or left wing sources will be removed at the mods discretion. We have an actively updated blocklist, which you can see here: https://lemmy.world/post/2246130 if you feel like any website is missing, contact the mods. Supporting links can be added in comments or posted seperately but not to the post body.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source.
Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners.
The auto mod will contact you if a link shortener is detected, please delete your post if they are right.

That's true of household panels (which are great for offsetting your daytime usage, which is usually your highest usage), but that is generally not true of large solar installations that heat up a huge mass of salt until it's molten and then produce power from that source 24/7. Example: https://insideclimatenews.org/news/16012018/csp-concentrated-solar-molten-salt-storage-24-hour-renewable-energy-crescent-dunes-nevada/
TL/DR: large solar installations produce power 24/7 (yes, even when it's dark)
Solar thermal isn’t really what we mean when we say solar power. The vast majority, even at utility scale, is PV panels just like the ones on your roof. Historically, solar thermal was too expensive and PV panels are still far cheaper.
That said, for areas like CA that may soon approach maximum solar penetration it may deserve a second look because of its more consistent energy output. It will mainly be competing with batteries, pumped hydro, and new generations of geothermal technology. All of these are new and fairly unproven at scale so we’ll have to learn as we go which is the best option for the later stages of decarbonizing the electrical grid.
Geothermals been proven since the 60s. It's a sealed system, there's no pollution (even if the pipe popped, it's just water), stations can be planted next to preschools and daycares and no one would be the wiser.
If your state has mountains, geothermals prob the answer. If your state doesn't have mountains (Kansas, Florida, Delaware), being from Washington, I don't know how you guys can live there. Not being able to orientate by the horizon fucking weirds me out. Especially in fucking Florida. I was driving thru the Ocala "forest" and it's all Spanish moss and saw palmettos everywhere. You can't see more than 10ft into the forest, and that's when I noticed you can't see the sky thru it either. It's just barely slivers of rays making it to the floor. I've never felt so claustrophobic in my life. *shudder fuck florida
I didn’t mean geothermal was entirely new but traditionally it has been limited to very specific geologic conditions which have largely already been developed. Newer technology (ironically pioneered by oil and gas drilling) has recently made many more sites possibly economical. But as with the other things I listed, these new types of geothermal plants are still somewhat unproven and expensive. I know they’re being investigated but so far very few have been built.
I wonder if they could drill down and capture the heat from the hotspot under Missouri.
Alaska, The Rockies, Yellowstone, the Sierras and the Cascades are all no brainers.
And Hawai'i for obvious reasons.
No. We're absolutely NOT poking a hole into the world ending super caldera.
Don't need too, you just need to boil water (or ammonia, or propane, etc) to spin turbines and Yellowstone does that on the surface
I’m not familiar with the geology of Missouri but it mostly depends on how deep you need to go. The deeper the more expensive it will be to build.
I saw something recently which is the same principle as molten salt, except the medium never melts, is stable, and... iirc is pretty much just carbon. I was trying to look for a source and all I could find was the equally-encouraging news that the humble red brick has now been turned into a capacitor (with a wall of bricks being able to perform as a supercapacitor)
