While businesses have always been careful about how much they spent on electricity, today’s displays are making it a lot easier to keep bills lower — and the environment safer.
For example, we measured a four-year-old 27-in. Apple Cinema Display as using 101 watts of power. However, the three 27-in. displays that we’ve tested in this roundup of environmentally smart monitors — AOC’s E2752VH, Dell’s UltraSharp 27 UZ2715H and the Philips 271S4LPYEB — use an average of 26.4 watts.
Assuming the display is used for 10 hours every business day and that power costs 12 cents per kilowatt-hour (the national average), the Apple Cinema display costs $29 for the year while the three reviewed here average an annual cost of $9.32.
In addition, all three of these displays all carry the EPA’s EnergyStar logo and boast wide screens that can display full HD resolution. And according to the EPA’s Greenhouse Gas Equivalencies Calculator, every kilowatt-hour of power saved equals 1.5 lbs. of carbon dioxide that isn’t spewed into the atmosphere.
