Electricity consumption at home, what is your consumption?

Sorry, but that is not normal, I also have KNX and a server, but the latter only needs 50W and not 350W. Just as an example. Is that some old discarded thing that consumes so much power? Investing in efficient components helps a lot. What is running there that it constantly draws 350W?!

11,000 kWh per year is roughly 30 kWh per day. Regardless of the technology installed, that is way too much, even with servers, air conditioning, controlled residential ventilation, etc.

As a single person with around 3,000 kWh, I already feel like a large consumer. However, that also includes a home office with two computers and monitors, the large waterbed, and a lot of cooking.

Sounds maybe stupid now but I think you can’t compare yours with my server, a server with 50W can’t have computing power and mine does. It has 4x GPUs installed alone (although not high-end) and everyone at home has a VM assigned with the GPU and KVM for mouse+keyboard. It is also a data server (ZSF-Z2 with 12 drives), TV server, etc. It doesn’t help to rely on so-called efficient components because they already are. It’s simply the amount that is inside this server.

Please don’t generalize, I don’t want to discuss this here, it is what it is. The technology without air conditioning, controlled ventilation, indoor+outdoor lighting (there are 20-25 pcs at 3-5W each), garden pump, etc. simply consumes about 40% of the total consumption. I’m okay with that and can live with it.

Would you like to explain what the VMs with passed-through GPU are for?

1x Kodi Media Center, 3x regular desktop PCs (GPU server -> HDMI to dual RJ45 -> dual RJ45 to HDMI -> monitor in the room where you want to work, plus mouse and keyboard.
Remaining VMs: data server, audio server for Airplay, web server for home automation, CAD VM to name just a few.

If you can live with it, then it's okay. Still, you have power guzzlers somewhere to generate that electricity consumption. 4,500kWh for "technology" per year? And then not even special technology. 12kWh per day just for servers and accessories is crazy. If everything runs 24/7 (and for example the data server, TV server, the VMs, etc. shouldn't do that - or are you all online 24/7?), that's over 500W continuous power. Crazy! And even crazier, what you consume for the rest - 6,500kWh. Sorry, but I just want to understand how one can waste so much electricity.
