Appliances Hog More Energy Than High-Tech Gadgets

Carl Bialik from WSJ writes "A tech columnist looked around his home and wondered, 'All these TVs and cable boxes and computers and computer gear and chargers for various adapters have to be sucking up a lot of power, right?' So WSJ.com's Jason Fry bought a power meter to find the biggest power hogs in his home. They weren't his newfangled gadgets: 'The heavily used agglomeration of PC / two monitors / printer / hard drive / speakers in my downstairs study costs a bit more than $10 a month. The PC in our bedroom costs about $6 a month. The upstairs laptop? Less than $1 — a bit more than other always-on gadgets such as the router, cable modem, wireless repeater and Airport Express. So what were our apartment's power hogs? The lights and the dryer. I estimate our lights cost us around $30 a month, nearly a third of that from a chandelier with eight bulbs. Then there's the dryer. I don't know exactly how many watts it uses, but estimate it's costing us at least $25 a month.'"

    Time to get those compact fluorescents. I have them in all but a few of the sockets in my house, and I estimate they save me big $$ given how much we have the lights on (there's almost always someone home, and I'm a night owl).

      cant do what now?

      also, someone up above made a comment about LED lights and got moderated troll. he is correct, LEDs are the next thing in lighting, as soon as the cost comes down. considerably more efficient than CFs.

      last note. i put CFs in my current house when i moved in 4 years ago. i havent had to replace a single one yet. and i too am a night owl.

      He was probably modded a troll because he was trolling.

      It is a misconception that LED fixtures are more power efficient than CF or other traditional "hot wire" light sources. Compared to your typical compact fluorescent bulb at the magical "100 watt incandescent" equivalent light output, they are in fact about the same. Fluorescent tubes are quite a bit better.

      There are however some new high-flux LED's in development that are cracking the previous 100 lumen/watt ceiling, but they still have a *long* way to go until they are cost competitive with any other light source.

    This isn't a suprise at all. Residential energy use is well documented in the EIA's Residential Energy Consumption Survey. The DOE runs these once every 4 or 5 years. Heating > A/C > Lights/Fridge/Cook/Clothes > gadgets.

    Things might change as people consume their 8h/day TV on 60" plasma space heaters.

    Actually it was probably that and the fact that where I lived, the gas companies were de-regulated and that was a clusterF*K of mess right there.

    You had to pay for the use of gas which was cheaper wholesale (which benefited business that pushed for deregulation) but marked up well over the original prices for residential customers and you had to pay for the billing of gas from the gas marketer which was a new charge.
    The deregulation was sold as cheaper gas for all but it ended up costing way more than they imagined, Natural gas prices rose insanely on top of that, and people that couldn't pay for the increase of both had to freeze in the winter.

    Safety is definitely the concern with natural gas. My brother is both an EMS first responder and part-time firefighter.

    Blah blah blah. I'm the Fire Marshal of a small town in PA. Most fires (not just in my town) are caused by cooking, and have nothing to do with the fuel used. It has little to do with the exact method of heating, its just that its hot. It's normally because of carelessness (especially including lack of maintenence). This includes crappy old gas stoves with no thermocoulpes that aren't properly mainteined. It includes overloaded elctgrical circuits. It includes filty ranges that have dirt and buildup catch fire during normal usage. It includes imporperly installed applicnces that don't vent correctly. It includes decrepit electrical wiring in the wall supplying a 30 amp 240v circuit.

    Don't kid yourself that gas is a higher risk. Improperly installed, improperly mainteained, and imporperly used are the real risks.
