Energy Conservation PPT by C.Thole


Published on

This a power point presentation comparing the results of one week of energy use with a 1500 watt un-insulated electric kettle with a 3000 watt UK style insulated Kettle. It also projects the energy savings for 1500 people over 10 years

Energy Conservation PPT by C.Thole

  1. 1. Energy Conservation Project For Partial Fulfillment of ED 630 Fall Semester, 2008 MAT Program UAS By: Cory Thole
  2. 2. The Question: How much energy can I save if I replace my un-insulated electric water heater with a more efficient, insulated electric heater?
  3. 3. Methodology: 1: Record the # of uses for one week, the amount of time needed for each use, average amount of H 2 O used each day. 2: Determine energy use and cost for 1 week of use. 3: Research other kettles and similar studies. Determine energy and cost differences between my kettle with an insulated kettle.
  4. 4. One Week Totals for: Uses Per Day, Time needed to Heat H 2 0 Per Use, Estimate of the Amount of H 2 O Consumed Per Day
  5. 5. Energy Use and Cost for One Week of Coffee Consumed. The use and cost was then projected for one year, 10 years and for 1500 people over a 10 year period
  6. 6. Web Search Results for Similar Studies The source for the following information and table of research results were found at Electric Kettle Land Some very rough numbers: Energy, in watt hours, required to boil 4 cups of water using various methods Method Power (watts) Time (hours) Energy (Wh) UK electric kettle 3000 0.031 92 US electric kettle 1500 0.074 110 US 7-inch electric coil 2000 0.077 154 Med-sized gas burner 2637 0.129 341
  7. 7. Energy Use and Cost determinations for the UK 3000 watt Electric Kettle using the data collected in my study. Note: These calculations were not only projected for 3000 watt kettle, but, also one that is insulated and therefore only requires 1 use per day for 4 cups of H 2 O. Since four cups of H 2 O was the avg. amount consumed per day these #’s would be fairly accurate for this study and comparison of usage.
  8. 8. <ul><li>Potential Discrepancies in data collection </li></ul><ul><li>Boiling times were not exact. Time to boil water are estimates to within 30 seconds. </li></ul><ul><li>Volume of water being boiled was not determined. The volume of water varied between uses and this would have affected the time needed to boil the water. </li></ul><ul><li>Differences of starting water temp was not taken into consideration which could have affected boiling times. </li></ul>
  9. 9. Questions for Further Study: * If you already own a use an un-insulated electric kettle that works well, how does the amount of energy conserved compare to the amount of energy used to construct the new insulated electric kettle? * If you heat water using an electric or gas range, what would your energy and cost reduction be by switching to an insulated electric kettle? How much energy would be conserved if your entire community switched to insulated electric kettles instead of ranges.
