Erin's Energy Conservation Project

  1. 1. Research Project:<br />Is unplugging idle appliances worth it?<br />
  2. 2. The Heroes of Our Story<br />Head Investigator Erin <br />&<br />Executive Investigatory Assistant Brett<br />
  3. 3. Observation #1:<br />They were already pretty energy-conscious.<br />Lights off<br />Energy-saving bulbs<br />Appliances off when idle<br />Mostly. . .<br />
  4. 4. Observation #2:<br />They still had dozens of appliances plugged in at all times!<br /><ul><li>Piano

  20. 20. Methodology<br />First: Procure a watt hour meter<br />Colleagues said to try:<br />Public library? <br />No luck – waiting list months long. <br />School library? <br />Yes! “Kill-a-Watt” meter in stock! <br />
  21. 21. Methodology<br />Second: Consult energy bill <br />Total kilowatt hours consumed in October: 286 KWH<br />Total Bill: $27.10<br />Translation: <br /> Cost = $00.09476 / KWH<br />
  22. 22. Methodology<br />Third: Measure ‘phantom’ energy draw per appliance and determine feasibility of regular and recurring unplugging.<br />Woo! DATA-COLLECTING TIME!<br />
  23. 23. Data Collection: Preparations<br />First, Erin drew up a spreadsheet. . . <br />. . . and sat Brett down <br />for a little “talk.” <br />(wherein they estimated<br /> “Y” for each appliance)<br />
  24. 24. Data Collection<br />Then the Kill-a-Watt meter did its duty <br /> again. . . and again. . . and again. . .<br />. . . and the unplugging schedule was attempted for one week.<br />
  25. 25. Data Collection Errors<br />DVR and refrigerator data unrecorded. <br />Sloth<br />“I don’t wanna move the fridge!“<br />and Covetousness<br />“But that’ll erase all our shows!”<br />Only a few minutes spent measuring each appliance.<br />(Kill-a-Watt = more accurate w/ more time.)<br />Only spent 1 week following unplugging schedule – feasibility still unsure. <br />
  26. 26. Data Analysis:Google Docs/Excel Spreadsheet<br /><ul><li>Desktop (ON) data not included in “totals” calculations.
  27. 27. Computers account for WAY more energy draw than anything else I measured! </li></li></ul><li>Data Comparison<br />Phantom power accounts for 5-10% of all energy used in homes in Canada, but accounts for only 2% of mine! Also, from nova energy:<br /><ul><li>My CRT desktop display: 5.65 Watts (sleeping)
  28. 28. Theirs: 12.14 W
  29. 29. My laptop LCD display: 42.68 W (hibernated!)
  30. 30. Theirs: 1.38 What?!</li></li></ul><li>What it means for me:<br />Computers draw a TON of energy!<br />Laptop accounts for 2/3 of total “phantom” energy and cost<br />Desktop tower, left ON (as it IS), drastically increases energy & cost if included!<br />$40 per year may not be worth unplugging so many things daily. . . <br />But $60 just for shutting off the desktop? YES! That’s worth it.<br />
  31. 31. Plan going forward:<br />Unplug laptop EVEN when hibernating<br />Take 5 min before bed to unplug major appliances like TV & printer<br />Unplug piano, speakers, and PS2 except when in use<br />DEFINITELY turn off desktop computer when not in use!<br />
  32. 32. Further questions:<br />What DOES make up the majority of my energy bill, if not phantom energy?<br />Why is my LCD display so much less energy-efficient than some?<br />How many other people spend almost $100 a year just because they never turn their computers off?<br />
