absurd. Uranium mines need huge exclusion zones. In fact the biggest ones have large enough exclusion zones that more solar energy could be harvested than the energy content of the uranium underneath.

Panels are also cheaper than most fencing, and easy to DIY install.

"bad" solar areas are actually amazing for 9 months, and if you heating needs are met by other means, then winter can keep the lights on and still do cooking. The path to meeting winter heating needs is hot water and "heated dirt/sand" storage with hydronic floor heating (where more water is delivered at 30C is easier to manage than radiators at 80C) that can be stored during ample fall solar with no heat or cooling load.

using old/existing FFs 3% of the time instead of 100% is a 97% emission reduction.

2gw, but yes, before any operational/maintenance costs that is $17.5/watt. Solar is under $1/watt, and sunny AF.

solar today is warranteed for 30 years. No reason to replace before 60 years compared to adding more beside it.

This is US centric, and panels are 1/3 cost in China, batteries 1/2, and labour/land 1/2 ish too.

just 17 kWh of battery storage is enough to turn 5 kW of solar panels into a steady 1 kW of 24-hour clean power

This is a bad model, though they are saying 3.4 hours of storage, and LasVegas as their best site. AC use is typically day only, but heat waves do make it a 24 hour demand issue on the longest solar production days. For LV, 5kw of solar will produce 32kwh/day, ranging in seasons from 29-35.5kwh. Already a problem for their 1kw "transmission setup" in that production is higher. The 2nd problem is that there is/can be higher demand during the day than night, due to AC.

The biggest problem of all is a battery in LV, even with 2kw transmission per 5kw solar, would charge in winter up to 19kwh of batteries. Summer 21.5kwh. The 2 big variables are batteries vs transmission size, and demand shifting opportunities, where necessarily fully charging batteries every day is a cost optimization, though fully delivering power on highest demand days is a revenue/price optimization.

cost assumptions are $563/kw solar-electrical hardware, and $181/kwh batteries. They may not include land and deployment costs. They use outdated pessimistic 20 year lifetimes. They have terrible comparisons to coal and NG as well.

Both coal and NG plants cost the same for basic peaker plant. A double efficient NG plant costs double, but loses flexibility. They have variable fuel costs and relatively fixed operation costs. Before covid, all 3 options cost $1/watt to build, giving a huge advantage to solar for not having fuel/operations costs.

A much easier way to model cost of solar+battery system is independently. Solar at $563/kw in LV to make 10% "yield" per year (covering full financing and a healthy profit). needs $56.30 revenue/year = 2.4c/kwh = $24/mwh. Even $1/w US system requires 4.27c/kwh The same base profit over operational costs as FF plants. Batteries last 30 years too, and 10% yield means a discharge/charge profit requirement of 5c/kwh at night, with possible double cycling from clouds/frequency balancing, or lunch cooking demand spike, where any profit is bonus profit.

So as long as duck curve/early evening/morning breakfast electricity markets are 7.4c/kwh TOU "wholesale"rates or higher, and daytime rates above 2.4c/kwh, solar + batteries (that fully charge every day) then that far beats any new dead ender energy plants. Also, for a 1gw transmission line, compared to OP model, you only need 1.7gw solar instead of 5gw.

In short term there are existing FF plants that can serve as backup, and where it is extremely undesirable to have any human activity in their surrounding areas, host solar to piggy back on their transmission capacity. That these plants were paid 20-40c/kwh to provide 10%-20% of power needs, with a combination of per kwh pricing, and fixed "stay ready for backup" payments, would permit these plants to stay open/operational. In short/medium term, EVs are a great resource to replace both utility batteries, and backup FF plants with more solar. Being paid 3-10c/kwh profit (depending on demand primarily from nightime AC/heating)

In long term, the path to solar+battery/EV power every day is much more solar with H2 electrolysis. $2/kg costs are already achievable today with 2c/kwh "surplus solar" input. It is an even more rapidly advancing tech/cost efficiency field. $2/kg is equivalent for a FCEV to $1/gallon gasoline vehicle range. It is 6c/kwh CHP (free domestic hot water energy), and 10c/kwh electric only energy, in addition to many chemical applications such as local fertilizer production. Electrolysis of NG is a more efficient (than water electrolysis) green H2 process that produces carbon black as byproduct. A solid precursor to graphene and battery electrodes.

H2 works today for places outside LV, where solar is much more variable. In Canada where long summer days may not need AC, high saturation solar can drop below 2c/kwh for 9 months, but be worth 15c/kwh for 80-90 days. A balance between existing energy systems and new solar works everywhere in the world. H2 export/import infrastructure also cost efficiently displaces much FF energy.

As long as daytime wholesale electricity rates in LV are above 2.4c/kwh, they need more solar. A similar number can be calculated elsewhere. Nuclear and more expensive combined NG energy cannot compete because daytime solar will cut into the hours they can sell energy.

Do I speak Ierland-ish? Mabey not, could be weird, but I got the one that must be Italian, and then I can pick English from there. Except I glossed over Groot-Brit.... because Groot couldn't be what I was looking for.

A problem with PikaOS is that the log files seem bad or I couldn't find the right one. Lots of seemingly amateur errors in log (no permission for system to write to system) that don't seem to lead to imminent crash. Log files don't pick up having to hit power switch maybe.

My main question was the easy "did a distro switch solve sleep issues for anyone"? Maybe switch to Mint would at least have more google hits on solving issues? Someone downvoted the "switch to x11 graphics driver before sleep" try, and I'm losing patience on tracking it down as you suggest.

maybe switching to x11 driver before sleep would solve it from that thread :(

Maybe scarier roads make you drive slower?

I assume this includes pedestrians and cyclist deaths? It's by population rather than by "car" or "km driven" but I'd like to see a per county breakdown.
