This commercial LG LED[1], suitable to be on 24/7 has a power reduction mode at 100 watt. Let's assume that works when it is in screensaver/art mode and it would use 2.4 kWh/day. A Tesla model S can get 240 wh/km, so the energy use of the display would power an electric car for 10 km. so for a year then it would be the equivalent of moving an electric car 3650 km. I don't drive that much, but it is actually about half of my yearly driving averaged over the last 10 years. Personally I rather turn that screen off and power my next car with it. Edit: just saw you said 16 hours. Well you can do the math. :) [1] http://www.lg.com/uk/commercial-display/lg-55XF2B http://www.lg.com/uk/commercial-display/lg-55XF2B [2] https://my.teslamotors.com/forum/forums/tracking-lowest-kwhkm-whm https://my.teslamotors.com/forum/forums/tracking-lowest-kwhk...
