My rack is about 500W, up to about 700W when the backup server kicks on (lots of spinning disks).
That’s a UniFi Dream Machine Pro, UniFi 24 port switch (powering two APs), 3x Dell R620s with a few SSDs and NVMe, and 2x Supermicros (one of which is the aforementioned backup server), each with a lot of spinners. Also some additional load from the overhead of the rack UPS.
I pay about $0.08/kWh, although with the base fee of $40 it's more like $0.11/kWh. In any case, it means I pay maybe an extra $30-40/month for my homelab, plus whatever additional heat load costs it places on my A/C.
If I moved to somewhere where electricity was significantly pricier, I would probably either invest in home solar, compress compute to a single node, or both.
