Does a cable modem use a lot of electricity??

I'd imagine that it would not really be significant enough to turn it off, but I dunno. . .so about how much electricity does a cable modem use?

Answers:
Actually a cable modem uses less electricity than your pc, in fact, it uses only about 1.5 times as much as a semi-new cordless phone (2.4 Ghz or up). If it used more than that, the heat problem it would have would fry itself!

Best to leave the thing on when not using it. You should only turn it off when thunderstorms are in the area.
very little, 550 mili amps, this alone is one of the smallest measures of power, a usb port will output about 500 ma, there is noreason to be turning it off.
it is the total power that matters at the operating voltage (not merely the current), which is neglibigle, so very less electrical comsumption, u may keep it on all the times .
