Research Project: Is unplugging idle appliances worth it?
The Heroes of Our Story Head Investigator Erin & Executive Investigatory Assistant Brett
Observation #1: They were already pretty energy-conscious. Lights off Energy-saving bulbs Appliances off when idle Mostly. . .
Observation #2: They still had dozens of appliances plugged in at all times!
Plant Lamp. . .
Questions: How much energy and money could they save by unplugging idle appliances? How feasible was it to do this seven days a week?
Methodology First: Procure a watt hour meter Colleagues said to try: Public library? No luck – waiting list months long. School library? Yes! “Kill-a-Watt” meter in stock!
Methodology Second: Consult energy bill Total kilowatt hours consumed in October: 286 KWH Total Bill: $27.10 Translation: Cost = $00.09476 / KWH
Methodology Third: Measure ‘phantom’ energy draw per appliance and determine feasibility of regular and recurring unplugging. Woo! DATA-COLLECTING TIME!
Data Collection: Preparations First, Erin drew up a spreadsheet. . . . . . and sat Brett down for a little “talk.” (wherein they estimated “Y” for each appliance)
Data Collection Then the Kill-a-Watt meter did its duty again. . . and again. . . and again. . . . . . and the unplugging schedule was attempted for one week.
Data Collection Errors DVR and refrigerator data unrecorded. Sloth “I don’t wanna move the fridge!“ and Covetousness “But that’ll erase all our shows!” Only a few minutes spent measuring each appliance. (Kill-a-Watt = more accurate w/ more time.) Only spent 1 week following unplugging schedule – feasibility still unsure.
Data Analysis:Google Docs/Excel Spreadsheet
Desktop (ON) data not included in “totals” calculations.
Computers account for WAY more energy draw than anything else I measured!
Data Comparison 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:
My CRT desktop display: 5.65 Watts (sleeping)
Theirs: 12.14 W
My laptop LCD display: 42.68 W (hibernated!)
Theirs: 1.38 What?!
What it means for me: Computers draw a TON of energy! Laptop accounts for 2/3 of total “phantom” energy and cost Desktop tower, left ON (as it IS), drastically increases energy & cost if included! $40 per year may not be worth unplugging so many things daily. . . But $60 just for shutting off the desktop? YES! That’s worth it.
Plan going forward: Unplug laptop EVEN when hibernating Take 5 min before bed to unplug major appliances like TV & printer Unplug piano, speakers, and PS2 except when in use DEFINITELY turn off desktop computer when not in use!
Further questions: What DOES make up the majority of my energy bill, if not phantom energy? Why is my LCD display so much less energy-efficient than some? How many other people spend almost $100 a year just because they never turn their computers off?
