> A proposed solar farm on the Ute Mountain Ute Reservation will have 2.2 million solar panels > Annual capacity is estimated to be about 756 megawatts. 756 MW/year = ~2 MW/day = less than 1 watt per day per panel? I get that the sun doesn't shine 24/7, but even so that seems way off. What am I missing? Maybe the 756 MW figure is daily instead of annual?

MW is power, MWh is energy. So annual should be 7564.5365 MWh

MW is power, MWh is energy. So annual should be 756 4.5 365 MWh

Watts are a rate (energy/time), you don't need to divide them by time again.

756 MW is the peak power rate, not accumulated amount of power that will be generated per year.

> Nuclear energy is the real future At present in the US there's no reactor that anyone will build. No one will build any more big AP1000s after the unmitigated financial disasters that were its 2 initial projects. Everyone has put their faith in small reactors (SMRs) but the only one with an approved design (NuScale) had its initial project fail after a Utah utility coalition fell apart. The NuScale project that fai…

If your environmental regulations prevent you from saving the environment by making it too expensive to save the environment, maybe you have too many environmental regulations? The medium term future of energy in the US at least is california, ie ridiculously expensive and unreliable. Hopefully costs will eventually come down as we get enough batteries and grid infrastructure in place so everyone can have their india…

There's site in FL that has all approvals in place, no environmental issues are barriers. It was to be the next project after the first 2 AP1000 and was cancelled after their experience. The economics of such a project have improved substantially since then due to the IRA's nuclear production tax credit (thanks Biden).

Yet no one has picked up this project. Why? Because the construction risk is too great, not because of environmental regulations.

The article is bad, as so often happens with units... The project site: https://www.sunbearproject.com/

971MW, producing up to 1700 to 2400 GWh/year.

That puts it at 2471 hours/year of full-power production equivalent, or 28%. That's good - it's a nice area for solar.

Should be more like 756 GWh

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?

Back in the day I worked on seismic field crews in that region.

Each crew had field archaeologists and biologists and representatives from the tribes and Bureau of Land Management working closely with us to insure that we followed all procedures to protect sensitive areas from disturbance.

That meant in practice that local or BLM archaeologists and biologists led the way across the area where we intended to acquire data. Just as you see in the photos in the linked presentation (user 1970-01-01), teams of experts surveyed the land looking for sensitive or threatened plants and animals and archaeologists identified areas with cultural artifacts. These areas were flagged and that flagging placed them off limits to our operations. They were No-Go areas. We had permission to operate within a fairly narrow easement across the landscape with strict guidelines about vehicle access, allowable damage to existing vegetation and the landscape, trash removal, etc since that region is very arid and small things like orange peels become items that are recognizable centuries after they are discarded.

For this survey I expect that they staked the potential affected area and walked every bit of it using pin flags to mark things that are not to be disturbed. The area is only about 8 square miles so it shouldn't take that long.

756MW of capacity will produce ~3,024 MWH per day

“756MW of annual capacity” doesn’t make sense, given that MW is a measure of instantaneous power. They might mean that the average daily peak output over the whole year is 756MW?

> 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?
