I love journalistic license: Andrew Fanara doesn't even have a wife.
Anyway, at the current state of development, it makes much more sense to buy a big-screen LCD than plasma if you are concerned about energy consumption. LCD rear projection TVs aren't as thin as the true flat panel, but more affordable than the flat-panel ones now (and still much thinner than CRTs). Mine is Energy Star-rated and tested at 0.75 W in standby mode (off). But as the article noted, that's not where the energy is used--it's mostly in active mode.
Week after next, as the article noted, we are having a meeting, first to discuss how to reign in TV active mode energy consumption, followed by a day to look at how to reduce set-top-box consumption (those are real hogs..even off, they consume 20W of power.) Typically, this means that by end of 2006, we'll likely have a specification in place for TVs and STBs that will finally give consumers a choice between the hogs and the efficient models.
I think the interesting point in the article is that we've found that a big TV, combined with an set-top box (and perhaps second or third ones in other rooms), combined with a DVD player, combined with a receiver and stereo system, can now add up to consume more electricity than your refrigerator (and US refrigerators are now the most stringently efficient in the world).
The problem is, none of these boxes talk to each other. The DVD player doesn't know if the TV is on--the TV doesn't know if the stereo is on, etc.--and a lack of a communication protocol among these devices makes it difficult for manufacturers to build in mechanisms to power down the box when ithe box its connected to is not in use. A "smart power strip" (commercially available now) is one option--plug all your stuff into this, and it can sense the on/off state of each box, and shut other boxes down accordingly. Only the set-top box presents a problem, since it has to be in some power mode all the time since the decryption codes are sent over long periods of time to prevent hacking, and they, unfortunately, are the biggest offenders in energy waste. It wouldn't cost much to design one that could stay on in low power mode, but given the fact that the design specs are from the cable companies, and the boxes are built by manufacturers like Motorola, and consumers can't buy them directly, it's difficult to provide motivation to spend the money to design it lower. So we hope an Energy Star spec will provide that motivation.
