  • 1. To Dry or Not to Dry? By: Kristin Teeples
  • 2.
    • How much energy would I save if I air dried my hair every morning instead of using a hair dryer?
    • How much money would I save?
    • How many pounds of CO 2 would I prevent from being emitted into the atmosphere?
    My Questions:
  • 3. Background ? ? ? CO 2
  • 4. What the heck is a pound of CO 2 ?
    • One pound of carbon dioxide gas has the volume of 9 cubic feet . You could store 2 pounds of carbon dioxide in the average kitchen refrigerator.
    • 454 grams in a pound
    • 1 mole (6.022045 × 10 23 ) of carbon dioxide molecules = 44 grams (16 + 12 + 16)
    • 454/44 = 10.32 moles of CO 2 per pound
    • 10.32 * 6.022045 × 10 23 = 6,210,000,000,000,000,000,000,000 CO 2 molecules! in 1 lb
    • 1 Kilowatt-hour = 1.37 pounds of CO 2
  • 5.
    • Check wattage of hair dryer
    • Timed how long to dry hair
    • Look at energy bill
    • Calculations
    Methodology:
  • 6.
    • 1. Blow Dryer = 1875 watts (1.875 kw)
    • Time to dry hair = 5 min every day
    • Time in a year: 5 * 365 = 1825 min (30.42 hrs)
    • Energy used: 1.875 kw* 30.42 hrs = 57.03 kwh
    • 2. 57.03 kwh * $0.079/kwh = $4.50
    • 3. 1.37 pounds of CO 2 /kilowatt-hour
    • 1.37 lbs CO 2 x 57.03 kwh = 78.13 lbs of CO 2
    • kwh
    • 485,187,300,000,000,000,000,000,000 CO 2 molecules!
    Data Collection/Calculations: (in one year)
  • 7. Conclusion: DRY!
