问 HN： “Dunkelflaute” 导致我的显示器黑屏
2 分•作者: bertili•7 个月前
我住在丹麦，据我所知，这里几乎不会遇到停电或电网问题。我家窗外就有三台国家运营的风力涡轮机（虽然这可能在这里无关紧要），但我很容易就能判断出风力大小。
我的问题是，今天，以及冬季的某些时段，我们有时会遇到德国人所说的“dunkelflaute”——雾天，涡轮机停转，太阳能电池板也无法发电。然后我的显示器就黑屏了！有时候我可以通过反复开关几次来恢复，但很快它又会在“那些日子”里再次黑屏，所以我只能改用笔记本电脑工作。
过去几年我并没有理解这种诡异的关联/因果关系，但现在我清楚地看到了。
我的显示器（我非常喜欢，Dell UltraSharp 43 英寸，功耗 53 瓦）通过一根 HDMI 线缆（5 米长）连接到 Mac Mini M4。更换了 HDMI 线缆，问题依然存在。使用较小的 Dell 显示器时，则没有问题。好吧，没问题，换个显示器就行了。
等等……我开始害怕了——在 53 瓦的功耗水平下，真的存在“微弱”或“不稳定”的电力供应吗？这是否预示着一个 solarpunk 未来，数据中心吞噬了“优质电力”，而我们却只能使用“残余电力”？

I'm based in Denmark and blackout or power grid issues are a non issue here, as far as I know. I also have three state operated wind turbines when looking out the window (not that it probably matters here) but I can easily tell if the wind is blowing.<p>My problem is that today, and in periods during winters, we sometimes have periods of what Germans call 'dunkelflaute' - foggy weather where the turbines stall and solar panels go dark. And then my monitor turns dark! I can sometimes get it back after switching it on and off a few times, but it will soon go dark again on "those days", where I work on a laptop instead.<p>Previous years I didn't grok the spooky correlation/causation, but I clearly see it now.<p>The monitor (which I really like, Dell UltraSharp 43", running at 53 watts) is connected to a Mac Mini M4 via a HDMI cable (5 meters long). Changing the HDMI cable, the issue still persist. With a smaller Dell monitor, there are no issues. Ok, no problem, just change the monitor.<p>But wait... I got spooked up - is there is even such a thing as 'thin' or 'fluttering' electrical supply at this 53 watt consumption level? Is this be a first hint of a solarpunk future where data centers gobble up the "good electricity" and we are left with "leftovers"?
