P P And Sleeping Hours  C Omplete P P And Sleeping Hours C Omplete Presentation Transcript

  • Tennille Moses How wasteful am I during the sleeping hours?
    • How much energy does my computer consume when left on for a night?
    • How much energy is consumed when leaving a light on over night?
  • Research Process Steps
    • Ask a question
    • Google question
    • Determine data needed to answer question
    • Determine methodology for collecting data
    • Collect data
    • Analyze data
    • Draw conclusions
    • Present results
    • Identify questions for further study
  • Step #1- My Questions:
    • How much energy does my computer consume when left on for a night?
          • How much energy is consumed when leaving a light on over night?
    View slide
  • Step #2- Google question
    • Energy consumption known for some models, but not my model.
    • How to determine electricity usage
    • To calculate your costs use this formula:
    • Watts x Hours Used
    • / 1000
    • x Cost per kilowatt
    • = Total Cost
    • Sample technology timers
    View slide
  • Step #3- Determine data needed
    • Watts
      • Look on light bulb
      • Look on the bottom of laptop/ computer back
      • Computer (Watts=volts * amps)
      • Log of sleeping hours
      • Days in week computer left on overnight
      • Cost per kilowatt
      • Electric bill ( 0.126564)
  • Step #4- Determine methodology for collecting data
    • To calculate your costs use this formula :
    • Watts (Both computer and night light)
    • x Hours used
    • ( Log sleeping times)
    • / 1000
    • x Cost per kilowatt-hour
    • (Power Bill)
    • = Total cost
    • (Wattage × Hours Used Per Day ÷ 1000 = Daily Kilowatt-hour (kWh) consumption (Checked formula with another source)
    • Sleeping hours for seven days
  • Step #5- Collect Data
  • Step #6- Analyze Data
    • Computer- Standby
      • Twelve hours
      • $.04
      • Seems insignificant
    • Light-
      • Thirty-four hours
      • Only weekdays
      • $.26
      • Seems insignificant
  • What if I continued to leave my 60 watt light on over night?
  • What if I connected a timer to my light and bought energy saving light bulbs? What if 10,000 Alaskans did the same?
  • 60 Watt vs. 13 Watt and Timer
  • Step #7- Draw Conclusions
    • Original Questions:
      • How much energy does my computer consume when left on for a night?
      • How much energy is consumed when leaving a light on over night?
    • Personal use does seem insignificant until cumulative effect is considered.
  • Step #9- Identify question for further study
    • What other energy consumption factors are relevant to Alaskans and other patrons of harsh climates?
    • What specific Alaskan energy issues has the media targeted?
  • Step #10- Cite Sources
    • Websites used for formula and background information:
