Energy in an Hour {Infographic}

May 17th, 2011 by  

Ever wonder how much energy is used by your different major appliances or electronics? Or how much energy all such appliances and electronics in the U.S. use? Here’s some info on that for four big ones: TVs, computers, clothes dryers, and refrigerators.

Before checking it out, try to guess how much each of these use in an hour — see how close you come!

Of course, these are the averages. By buying energy-efficient electronics and appliances or using such things less, you can make a big difference when it comes to energy use (and the size of your electric bill).

     I like infographics. I really do. BUT WHY DOESN’T ANYONE CHECK THE MATH BEFORE PUBLISHING THEM????? Would someone please go back and rework the figures for the computers!!!

    Why report KWhr per hour instead of just KW? 

  • Beautiful, Zach.

    Something about infographics make the data so much more loveable.

    None of us really want to give up our technical creature comforts, but most of us already have the sense that it’s wrecking serious havoc.

    Have you run across any good info on refrigerator defrost cycles/usage?

    I’m off the grid and once in a while I’ll check my system meter and think something wrong.  Turns out that the refer was doing its anti-frost thing.  Seems to pull a lot of power for a signficiant amount of time.  Something that could easily tolerate being part of the off-peak/response demand solution.

    I’ve found 400 watts, up to a half hour a day on line, but don’t know how accurate is.

    BTW, my Energy Star18 cu.ft. ‘off the storeroom floor’ refer uses less than 1kW per day, about 0.04kW per hours.

    • know nothing about it 😀  & think the infograph creators just used some general info, not experts either. anyone else know?
