Figured this out because I was curious- This would makeup about .17% of total US electricity consumption in 2022. Assuming 4 trillion kWh. https://www.eia.gov/energyexplained/electricity/use-of-elect... .

Also for context, the quoted 756MW figure is about 68% of a single AP1000 reactor.

Too bad no one wants to build AP1000s even though there is a site in FL with all approvals and the new Biden subsidy. That's how badly the two projects fucked up.

Largest in US, but pretty small compared to whats coming up. Todays news, ~$12B in Philippines: https://news.ycombinator.com/item?id=39408076 Edit: 3.58B, not 12 from another comment. Still, pretty large investment for Philippines.

Isn't the actual size important, and not the money involved?

I wonder if the tribes have enough autonomy to build transmission lines quickly. Just the Navajo Nation can build enough solar/wind and transmission lines within their reservation and probably connect to the grids in Colorado, New Mexico, Utah and Arizona. US is incredibly slow in building transmission lines, takes decades.

And, if they have enough autonomy to import Chinese panels (50% cheaper), a network of these nations can blanket the entire country with renewables.

Dang they went out and found 400+ of a rare cactus and avoided building on them? Anyone know how they actually did that survey? Like someone just goes out for days at a time and looks?

Not sure how it went in that specific case but yes, these type of impact studies are usually hands on, you go out into the field with a bunch of people and comb an area completely.

In case of a chip factory currently developed by Intel in Germany, they went out onto the 200ha (roughly 280 football fields) and found and resettled 7 rare hamsters. 2 of those had to be dug out: https://www.mdr.de/nachrichten/sachsen-anhalt/magdeburg/magd...

> But also, it makes sense not to transmit power too far from where you are

yep, they’ll waste the energy trying to transmit it

sounds like they’re going to be attracting bitcoin miners. they’re the only use case that’s able to be in the middle of nowhere without needing other infrastructure, like robust internet.

any other use cases you all know of?

This would greatly enhance the usefulness of tribal-electricity.

Yes, actual size, but also relative to the size of their economy. Considering Philippines GDP, this is significant.

Does anyone have a breakdown of the materials required to create 2.2 million solar panels? I worry that we measure solar strictly on the carbon emissions and not the full environmental impact -- such as that of land and mining of materials. Edit: I'm not advocating fossil fuels. I think solar makes a ton of sense, but it also seems crazy to think we could build enough solar + storage capacity for the world. Nuclear e…

Here is a great comparison of land use for different power sources, based on power output: https://ourworldindata.org/land-use-per-energy-source

Solar is roughly on par with coal, depending on the exact type of solar technology used. Of course you can put solar on existing structures, in which case the land use is negligible and on par with nuclear.

Regarding energy input, solar panels break even after about two years, I think (no source on hand currently). It would be quite easy to have solar panel production run entirely on renewable energy input.

Regarding the other resources, you can't really compare energy sources to one another, as all are using vastly different inputs and have different challenges regarding disposal of waste and recycling. You'd have to make a judgement based on impact. I.e. coal is really bad, because it produces CO2 which has potentially society-ending consequences. Nuclear has challenges, because the waste remains radioactive for so long. My personal impression is that solar has some challenges, but those are manageable and likely can be mitigated by regulating disposal and recycling of old panels.

And an AP1000 reactor costs about $6.8 billion to build, and substantially higher operating costs. 68% of the power for 14% of the price seems like a pretty good deal to me, there's a reason people are investing more in solar than nuclear, it's just more cost effective.

edit: Oh, and that $6.8 billion looks optimistic. This project with two AP1000s looks like it costs $30 billion. https://www.ans.org/news/article-3949/vogtle-project-update-...
