P P And Sleeping Hours C Omplete

  1. 1. Tennille Moses How wasteful am I during the sleeping hours? <ul><li>How much energy does my computer consume when left on for a night? </li></ul><ul><li>How much energy is consumed when leaving a light on over night? </li></ul>
  2. 2. Research Process Steps <ul><li>Ask a question </li></ul><ul><li>Google question </li></ul><ul><li>Determine data needed to answer question </li></ul><ul><li>Determine methodology for collecting data </li></ul><ul><li>Collect data </li></ul><ul><li>Analyze data </li></ul><ul><li>Draw conclusions </li></ul><ul><li>Present results </li></ul><ul><li>Identify questions for further study </li></ul>
  3. 3. Step #1- My Questions: <ul><li>How much energy does my computer consume when left on for a night? </li></ul><ul><ul><ul><ul><li>How much energy is consumed when leaving a light on over night? </li></ul></ul></ul></ul>
  4. 4. Step #2- Google question <ul><li>Energy consumption known for some models, but not my model. </li></ul><ul><li>How to determine electricity usage </li></ul><ul><li>To calculate your costs use this formula: </li></ul><ul><li> Watts x Hours Used </li></ul><ul><li>/ 1000 </li></ul><ul><li>x Cost per kilowatt </li></ul><ul><li>= Total Cost </li></ul><ul><li>Sample technology timers </li></ul>
  5. 5. Step #3- Determine data needed <ul><li>Watts </li></ul><ul><ul><li>Look on light bulb </li></ul></ul><ul><ul><li>Look on the bottom of laptop/ computer back </li></ul></ul><ul><ul><li>Computer (Watts=volts * amps) </li></ul></ul><ul><ul><li>Log of sleeping hours </li></ul></ul><ul><ul><li>Days in week computer left on overnight </li></ul></ul><ul><ul><li>Cost per kilowatt </li></ul></ul><ul><ul><li>Electric bill ( 0.126564) </li></ul></ul>
  6. 6. Step #4- Determine methodology for collecting data <ul><li>To calculate your costs use this formula : </li></ul><ul><li>Watts (Both computer and night light) </li></ul><ul><li> x Hours used </li></ul><ul><li>( Log sleeping times) </li></ul><ul><li>/ 1000 </li></ul><ul><li>x Cost per kilowatt-hour </li></ul><ul><li>(Power Bill) </li></ul><ul><li>= Total cost </li></ul><ul><li>(Wattage × Hours Used Per Day ÷ 1000 = Daily Kilowatt-hour (kWh) consumption (Checked formula with another source) </li></ul><ul><li>Sleeping hours for seven days </li></ul>
  7. 7. Step #5- Collect Data
  8. 8. Step #6- Analyze Data <ul><li>Computer- Standby </li></ul><ul><ul><li>Twelve hours </li></ul></ul><ul><ul><li>$.04 </li></ul></ul><ul><ul><li>Seems insignificant </li></ul></ul><ul><li>Light- </li></ul><ul><ul><li>Thirty-four hours </li></ul></ul><ul><ul><li>Only weekdays </li></ul></ul><ul><ul><li>$.26 </li></ul></ul><ul><ul><li>Seems insignificant </li></ul></ul>
  9. 9. What if I continued to leave my 60 watt light on over night?
  10. 10. What if I connected a timer to my light and bought energy saving light bulbs? What if 10,000 Alaskans did the same?
  11. 11. 60 Watt vs. 13 Watt and Timer
  12. 12. Step #7- Draw Conclusions <ul><li>Original Questions: </li></ul><ul><ul><li>How much energy does my computer consume when left on for a night? </li></ul></ul><ul><ul><li>How much energy is consumed when leaving a light on over night? </li></ul></ul><ul><li>Personal use does seem insignificant until cumulative effect is considered. </li></ul>
  13. 13. Step #9- Identify question for further study <ul><li>What other energy consumption factors are relevant to Alaskans and other patrons of harsh climates? </li></ul><ul><li>What specific Alaskan energy issues has the media targeted? </li></ul>
  14. 14. Step #10- Cite Sources <ul><li>Websites used for formula and background information: </li></ul><ul><li>http:// michaelbluejay.com /electricity/ </li></ul><ul><li>http://www.eere.energy.gov/consumer/your_home/appliances/index.cfm/mytopic =10040 </li></ul>
  15. 15.
