Portland here, Pacific Power around $0.12/kWh. Not terrible but I finally bothered to enable proper C-states in BIOS on my Threadripper box. Was idling at 140W, now 75W. That's $7/month for ten minutes in firmware settings.
Why did I leave it on "performance" for two years. Why.

Free tiers only here. Learned that Oracle Cloud's always-free ARM instances actually stay up if you don't abuse them. Moved my portfolio and a Discord bot there from a paid VPS. Saving ₹850/month which is my textbook budget.
Yes I check uptime obsessively — https://uptimerobot.com. No they haven't killed it yet.

Detroit, DTE Energy, ~$0.16/kWh. Bought a used Dell R720 for $200, immediately realized it pulls 200W idle. Sold it for $180 before the first bill hit.
Now on a OptiPlex 5060 SFF, i5-8500, 35W idle, runs Proxmox fine. The R720 lesson cost me $20 and a hernia moving it.

This. My ISP in Utrecht wanted €5/month for a static v4. Declined, run everything behind a single dynamic + Cloudflare tunnel. The v6 path is clean for my own stuff.
Also:
Because the BIOS default is "performance" and who reads motherboard manuals for fun. We all do this.

My homelab ate my electric bill and I would do it again
But seriously: learned that scheduling my TrueNAS replication to 2-5 AM only cut my peak-rate draw enough to matter. Time-of-use tariff, the off-peak rate is half. Saved maybe £12/month by moving bits around the clock.
The array still spins. I'm not a monster.
Barcelona, ~€0.18/kWh. Biggest save this month: actually read my solar inverter data. Found one panel string was underperforming 15% because a neighbor's tree grew. Trimmed it, gained that back.
Not a homelab thing but watts are watts, right?
Following this thread closely. Have a rack in the garage I've been afraid to meter.
This is the correct emotional response. Ignorance was warmth.
Did we settle whether Hostinger's Phoenix datacenter runs on APS or SRP? Looking at their shared plan for a side project and trying to guess the carbon intensity.
Also: has anyone actually measured a NUC 13 Pro idle? Thinking of picking one up.

Not settled, and I don't know offhand. Their site just says "100% renewable energy" which is marketing for RECs. The watts are still somewhere, like Berlin1 said.
Friend has one, sees 8-12W at the wall with an NVMe and 32GB. Solid box.
