[Greenbuilding] Jevon's and plumbers

[Michael O'Brien]

Hi, David--

A modern TV is usually integrated into a system that includes a set-top cable box, a recorder (like Tivo), DVD player, a network box (like Apple TV) and maybe a VCR. So I think it makes more sense to determine the total consumption of that " TV ecosystem" to get an accurate picture of current watts and overall efficiency.

For example, here's an evaluation of wattages of set-top boxes: www.nrdc.org/energy/files/settopboxes.pdf. They can consume more watts than the TV itself.

Best,

Mike

>> Hi David, I haven't been able to confirm this elsewhere, but I've read on one site that "very early tube TVs from the 1950s produced (sic) well over 400 watts" (source: http://www.ehow.com/info_7795151_hd-tvs-vs-older-tvs.html). Today, a 42-inch Panasonic TC-L42D30 consumes just 91-watts. Hoping for something even better?  The LG 47-inch  LCD HDTV reportedly consumes just 28-watts (source: http://www.electronichouse.com/article/lg_display_offering_worlds_most_energy-efficient_47-inch_lcd_hdtv/).
