How much does it cost to run a computer monitor in Hawaii?

$21/yr · median certified model

Hawaii is the extreme case for U.S. electricity costs: 46.6¢/kWh, roughly 2.5× the national average. The median certified computer monitor costs about $21 a year here — the same appliance would cost $8.49 at national-average rates. In this rate environment, the gap between an efficient and an inefficient computer monitor is often larger than the appliance's purchase-price difference over its lifetime.

Hawaii sits at rank 51 of 51 — near the very top of the cost table for a computer monitor. At local rates, certified models span $5.18 (Acer PE140WU_z) to $188 (PLANAR 2E0I1) per year — $183 of annual headroom that depends entirely on which unit you buy. For reference, the national extremes are North Dakota (12.3¢/kWh) and Hawaii (46.6¢/kWh); the same median computer monitor would cost $5.57 and $21 a year there.
