I'm not sure where you are getting that 118W number. I can't find it on that page. The energy guide[1] states 87 kWh per year at 5 hours per day so roughly 48

I'm not sure where you are getting that 118W number. I can't find it on that page. The energy guide[1] states 87 kWh per year at 5 hours per day so roughly 48W per hour rather than 118W so drop that yearly cost down around $100. Also I don't want to sound like I am shilling for Samsung, but there are various power saving options on the device. I'm not sure if those are included in the estimate. Either way, even in the markets with the most expensive electricity costs, it would take several years if not over a decade for this approach to match the initial price of the e-Ink option.
Also both these options are wasteful in the grand scheme of things. Yes, the LCD option will likely be more wasteful than the e-Ink version, but neither is particularly justifiable if you are concerned about waste. I would also venture a guess that on the full spectrum of environmental waste those two options are much closer together than either is to just throwing up an old fashioned art print on your wall.

- CydeWeys 6y ago> 87 kWh per year at 5 hours per day I said in my post I'm using 24 hours per day, not 5. Multiply your figures by 24/5 to see the 24/7 costs. > 48W per hour 1 W = 1 J/s. 48 J/s/hr would be some weird kind of accelerating power consumption, which is I assume not what you meant here.
- slg 6y agoI am no expert so it is entirely possible I am making a mistake with my conversions, but here is my math: 87 kWh = 5 hours per day * 365 days 87000 Wh = 1825 hours 87000 Wh / 1825 h = 47.7 W 47.7 W * 24 hours per day * 365 days = 418 kWh 418 kWh * $0.22 per kWh = $92
- CydeWeys 6y agoAgain, why are you using 5 hours per day? When used as a photo frame, this is going to be on for a lot more than that. The pathological case here is it's on for 24 hours per day, not merely 5.
- slg 6y agoBecause the 87 kWh total is based off the assumption of 5 hours per day. We need to use that to get to the actual wattage. Once I have the wattage, I can use that to get to the 24 hour per day 365 days per year usage of 418 kWh. Another way of getting there is taking the 87 kWh estimate and multiplying it by 24/5 to get 418 kWh.
- CydeWeys 6y agoAhhh, now I see what you're doing. I found a source that says 118 W though, so I guess it's just a case of dueling sources at this point. If someone owns one of these and has a Kill-A-Watt then we can find out for sure.
- omgwtfbyobbq 6y agoThe energy star rating gives you the power use when on. $10/year over $.12/kWh over (5hours/day*365days/year) is roughly 46W for the 32" version. https://pisces.bbystatic.com/image2/BestBuy_US/images/products/6405/6405713_eg.jpg;maxHeight=1000;maxWidth=1000 https://pisces.bbystatic.com/image2/BestBuy_US/images/produc...
- m463 6y agowow in california this will bump you into the next tier. if you had only these panels in your house, no other electrical use, you would pay: # | monthly ----------------------- 1 | $108 2 | $238 3 | $371 4 | $530 5 | $689 [ pg&e: 0-300kwh @ .24, 300-1200kwh @ .31, 1200kwh+ @ .38 ] it gets pricier with time of use + summer up to .48/kwh
