<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>I can attest to that. A few years ago we got new service that required a set-top box that could not be turned off—hitting Power Off didn’t actually turn the thing off (b/c the box wants to keep getting the data feed from the node). Threw a kill-a-watt on there and found each box sucking 40 watts — 24/7/365. I calculated that to be costing me about $3.50/mo since we have 3 TVs. I threw a Smart Strip power strip on each set-up, so whenever we turn the TV off, the strip cuts off the peripherals as it they’re being unplugged. When it comes back on it takes about a minute for the box to reboot—a pain in the rear to be sure—but worth it as far as I’m concerned. Talk about vampire load.<BR>
<BR>
I believe Energy Star is now unveiling a label for set-top boxes which has the potential to be a huge difference maker. But you’ll need to see if your cable provider has the new boxes and will swap them out.<BR>

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