The most efficient homelab hardware in 2026 — mini-PCs, SBCs, low-power NAS and networking gear — ranked by idle watts and real annual running cost.

What a 2-bay, 4-bay or DIY NAS actually costs in electricity per year at US, UK and German prices — and how to cut the bill without turning it off.

Seven practical, measured ways r/homelab users cut their electricity bill — from consolidation and C-states to drive spin-down — with real annual savings.

A practical guide to measuring real homelab power draw: plug-in meters, smart plugs into Home Assistant, UPS/PDU telemetry, and turning kWh into real cost.

Full 3-year total cost of ownership for a low-power mini-PC vs a cheap used rack server, including purchase price and electricity at US, UK and German rates.

Why idle power draw — not peak load — decides your homelab electricity bill, with a worked example showing how the wrong number can be 3x too high.
