I have a very serious issue with this!
What about the profits for coal companies! How are they supposed to make money! What if they go out of business!
WON'T SOMEBODY THINK ABOUT COAL INDUSTRY PROFITS!
They're going to cool off the sun if they aren't careful. /s
I seriously used to work with a guy who thought wind turbines might have negative impact on the environment because it was "taking the wind".
someone bolted thousands of solar panels to a place almost no one thought was worth it.
"Someone"
2026 journalism
"We went to bed one night, and when we woke the next morning, they were there! Someone must have bolted them on."
Did you know? If you leave dishes in the sink, they will magically be cleaned and put away the next day! I told by partner and then stared at me dumbfounded.
In the United States, this is called treason because it makes Donald Trump PP in his pants
The actual non-AI article about the dam: https://www.axpo.com/ch/en/energy/generation-and-distribution/solar-power/alpinsolar.html
Here are some images of the dam sourced from Axpo encoded from 117MiB to 626 KiB (720p AVIF)

It’s a good idea, if the dam faces a good direction (North probably isn’t worth it) even without the additional benefits of altitude.
Good shout.
Here is an older article on the start of construction from a publicly funded news organization:
https://www.swissinfo.ch/eng/sci-tech/switzerland-builds-biggest-alpine-solar-plant/46883572
Here is the article from when it was done (September 2022!), but this one isn't available in English I'm afraid:
As a primary source, here's the project page of one of the involved companies:

Edit: Corrected the first link. Had too many tabs open and posted this one by accident: https://www.swissinfo.ch/eng/archive-alpine-environment/construction-starts-on-first-large-scale-solar-park-in-swiss-alps/87531886
It's pretty rare to find a river that runs north, though.
Huh? There's no reasons for rivers to not run north, the longest river in the world runs south to north.
I went to find stats on how common or uncommon it is for rivers to flow north or south and instead I ended up learning that the major driving factor for the placement of tbe Canadian Border is a series of watersheds which largely dictate flow direction. Image attached.

So Canadian rivers are more likely to flow north and USA rivers mostly flow south.
Why the fuck would everyone say solar doesn't make sense up where it's cold and clear where anyone who knows anything about the topic knows that solar is most efficient?
Not only that, but it also works brilliantly on farms, giving sheep something to hide under for shade, makes their wool higher quality, and the earth underneath retains more moisture, and well as holding more dew for later in the day.
It is difficult to get a man to understand something, when his salary depends on his not understanding it.

...the assumption was simple, that solar belongs low and warm, on sunny roofs and flat fields, not up in the freezing thin air of the mountains.
Well that's a stupid assumption. what other kind of electronic works better when it's super hot??
The country makes plenty of power in summer, but runs short in winter, when demand climbs and it has to import electricity.
That gap is set to grow as the nation closes its nuclear plants.
Damn, two stupid ideas from the Swiss. At least the fabled "someone" put those solar panels up there. 🙄
Yeah, the fears about nucular are global I'm afraid. The Swiss decided 40 years ago that they would no longer invest in nuclear energy and massively reduce upkeep on the existing reactors, thereby making issues a self fulfilling prophecy. Most of the reactors have now reached their end of life, if not ten years ago. So turning them off is really a necessity, but building new ones now would be stupid.
I imagine they had to do a lot of calculations in order to be sure this installation would not compromise the dam. But if this could be applied in other locations, it could be extremely benificial.
Honestly, I think it wouldn't be a problem in any dam. I'm sure they made all the required studies but dams are so thick and made to withstand such great forces that a couple of solar panels bolted on would be negligible. I bet 10cm of water rise would be a way bigger load
Switzerland is one of the only countries where it makes any sense to do this kind of nonsense because they're already almost completely on renewable power. I shudder to think of how high the installation cost per watt is when you need rope access teams drilling into concrete. Some IRATA certified electrician probably bought a vacation home with the money from just this project.
'wow the panels are 50% more efficient during winter, and it only cost 1000% more to install compared to a conventional rooftop'
*Ok I checked, it cost about 3.6 CHF per nameplate watt. Roughly double residential rooftop solar in Switzerland, which itself is again about double what a ground mount array costs. So still bad, not nearly as bad as I thought. This also is only the original install cost. Apparently they've had to do significant repairs, including replacing 270 panels, because of snow and ice damage. From the bit of extra research I did on this I think the primary purpose of this install was to ease the path to getting more alpine solar installation approved. Because this definitely isn't economically viable and I don't think they expected it to be. But there is potential for economically viable alpine solar farms if they can get approval for development.
**By the way this article and the image for it are AI slop, the actual install is slightly less absurd than the article makes it look.
::: spoiler the actual dam
The install generates 3x more power than an equivalent solar farm at lower altitude during the winter months, but costs 4x more to build. Doesn't really add up. For a smaller investment you could have the same amount of winter production and 3x as much production during the other 3/4 of the year.
And? Its new information for future construction, highlights the importance of doing this along with any repairs or new builds where you're doing some of that work anyway.
Confirms the energy is there.
And its literally on a damn, so storing excess with pumped hydro is can be done with like 0 transmission inefficiency.
Yeah people and the media have this weird fascination with putting solar panels in new places. I don’t think finding locations to add them is as big of an issue for how much people seem to care and want to “solve” it.
I've thought for YEARS that we should to the same thing with the Hoover Dam. Should also mount wind turbines on the face of it to catch the updrafts out of the canyon. You all acting like green energy has to be mutually exclusive to one another. Wind turbine blades have a lot of surface area that could be covered in solar panels, which solves the issue of solar panels energy output decreasing with heat because then they'd always have built in cooling. No wind? There's still light and some wattage is better than no wattage. Put the turbine blade head on a giant hinge and they can catch rising air from the grounds' radiant heat at night. Free energy is everywhere if you just know where to look and how to take advantage of it.

That is a stupid idea. Blade weight is one of the biggest engineering issues for wind turbines.
I tried (but not very hard) to check what the highest altitude dam in the world is, but searches kept giving me the tallest dams instead. But, for anyone who's wondering, I also looked up what the highest altitude solar farm in the world is, and it turns out it's the Huadian Tibet Caipeng project, at 5,228 meters (17,152 feet) above sea level on the highest plateau in the world. I have to wonder if snow accumulation outweighs the benefits of the lower temperatures and thinner atmosphere.
usually snow slides off solar panels fairly easily since they are smooth, tilted, and absorb heat.
Maybe search for highest-altitude reservoirs instead of dams?
Quite a dam advancement.
An example of some great dam thinking by a group of smart dam people.
Article reads like AI trash. Is there an actual source?
There was a lot of news about the Muttsee Dam solar project a few years ago, so it's a real thing and a good thing. But it's hardly current news. It's been operational since 2022.
