I just got my electric bill, and being wary of , I got to thinking: how much of this is my TV? According to one test described in an informative article in the Christian Science Monitor (via Mark Schubin's Monday Memo from June 27), I have one of the more efficient kinds of TV: a direct-view CRT. Still, the EPA's methodology for rating TV power consumption is way out of date, so you can't really go by the Energy Star ratings of TVs as an indication of how much power it draws. Until the EPA modernizes its ratings, a few quick rules of thumb: big screens draw more power (duh), turning down contrast reduces consumption, and HDTVs--especially plasmas--are hungrier for watts than other TV technologies. Turning off the TV once in a while also helps.
