Up on the dam, almost everything that looks like a problem becomes an advantage.

The plant sits above the fog line, in thin, clear air that lets far more sunlight through.

The higher you go, the stronger and cleaner the sunlight becomes.

Cold actually helps, because solar panels work more efficiently when they are not baking in heat.

And then there is the snow, which acts like a giant mirror, bouncing extra light up onto the panels from below.

Scientists call it the albedo effect, and it can lift a mountain plant’s output well beyond anything possible in the valley.

A test site at a similar height recorded yearly output far above a typical Swiss plant.

    …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 think that the Chernobyl disaster made much more psychological damages than real ones, in the long term.

          Then there’s 3-Mile Island, which was 30 minutes from a meltdown. If that would have occurred, DC was in the direct path of the radioactive cloud.

        Yep, but require much more space. And it could be not available when you need it.

        I agree with you, content-wise, but there’s no need to insult people. It provokes emotions that add nothing reasonable and productive.

        Let’s work together on a better, kinder world <3

        So you’re happy to go without power after sunset then?
        Until we have more storage options or diversified sources then that’s what you get. Or do you think it will all happen by magic?
        Maybe try being less rude unless you have a solution that doesn’t just involve wishful thinking.

            Ffs this is exactly what I mean… To power Switzerland for only 6 hours (38GWh), you would need approximately 30,000 to 35,000 utility-scale batteries. Where and how exactly are you building them?

              Must solve all problems at the same time for entire country, can’t possibly wind things down while building up alternatives. Only good solution is nuclear, ignore all previous nuclear issues, they were one offs that only happened because people were stupid. We now smart humans will never have stupid or corrupt people.

              Really I don’t even dislike nuclear, some people treat it as the only option when there are clearly alternatives, and solar and batteries appears to be one.

                That’s what is happening but it not happening fast enough. Batteries are great but unless you build out a LOT of them and combine with intelligent grids and power consumption you aren’t covering the output of a nuclear power plant. If you are decommissioning a nuclear plant then you had better have alternative power available otherwise you end up like Germany who did that and then had pull a lot of power from Frances nuclear excess as well as burning extra gas for power. I like renewables, I have solar + battery at home, I’ve built flow battery models and fuel cells to experiment with. I’ve written software to turn my house (and hopefully include my neighbours soon) into a virtual power plant based on my houses output as well as the wholesale market price. It’s difficult to manage when people expect a light to turn on at any time they want. I just get tired of people saying renewables are the only option and when it inevitably isn’t just yet having to burn more fossil fuels when the existing nuclear plant can continue

                  That is rad. My father started with solar domestic hot water heating, then got some PV solar, never bothered with batteries (it was at a time when batteries kind of sucked). Did ok for our northern latitudes. Power company didn’t encourage it though which makes it feel like a bit of an uphill battle. I’m thinking of doing my own house but again, it seems like you’ve got to be the expert if you want to make it work, and power companies aren’t happy to have your contributions.

                  I guess I just get a bit - understanding when people say they are scared of nuclear. I do realize that in aggregate fossile has been way worse than nuclear.
