PCWattVault shows what your Windows PC costs in electricity, live and over months. It reads your hardware's power sensors (or a smart plug at the wall, or a laptop's own battery), prices every watt-hour with your real tariff (day/night, tiers, any currency) and keeps a local history with month-end forecasts. See which apps and parts draw the power, and why a spike happened. New in 1.1: an always-on-top mini window. No account, no cloud, no telemetry. Free.
