Energy Consumption by Household Appliances
Lot of discussion is available on Internet about power consumption by computers, TVs etc. Here is a good CNET Article about TV power consumption.
But it was interesting to read about power consumption by household appliances on this slashdot article.
Mostly what I read was in line with what I thought. Home heating and cooling is the biggest monster when it comes to power consumption. In fact according to wikipedia article about energy conservation, space conditioning roughly consumes 44%, close to half the total power consumed.
Insulate your house properly and it will work wonders on your electric bill.
Slashdot quoted text “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 $25 a month.”
Look at this table of appliances power consumption. The figures are sort of approximate. Definitely there will be a big variation. But it is overall good table for finding which appliances consume relatively high power.
Electric dryer consumes a humongous 4KW/H.
So if you run dryer everyday about one hour, you are using almost 4 x 30 = 120 KWH. At 10c/ KWH, and taxes on top of that, you are running in about 12-15$ per month. If you are running biggerloads, runing dryer for more time, or running on high heat cycles, you might be spending north of $25-$30 per month just for drying your clothes.
Just for reference, home energy consumption average figures from wikipedia article,
- space conditioning, 44%
- water heating, 13%
- lighting, 12%
- refrigeration, 8%
- home electronics, 6%
- laundry appliances, 5%
- kitchen appliances, 4%
- other uses, 8%
