Conserve Insight is a new in-home energy meter from Belkin that can tell you just how much energy the microwave and the toaster are really using. Most importantly, though, Conserve Insight can tell you how much it costs to power these appliances.

Belkin’s Conserve Insight measures how many watts your appliance draws, its carbon footprint and how much it costs to run. This cool information may or may not affect what you choose to keep plugged in, but it is still nice to know regardless.
