  1. Power = 4500 Watts Usage = 3 hrs/day Power = 1100 Watts Usage = 15 min/day Power = 500 Watts (range) Power = 3000 Watts (oven) Usage = 30 min/day each Power = 1500 Watts Usage = 1 hr/day Kitchen Appliances

  2. Power = 1100 Watts Usage = 10 min/day Power = 1500 Watts Usage = 15 min/day Power = 700 Watts Usage = 24 hrs/day Kitchen Appliances

  3. Classroom Appliances Power = 150 Watts Usage = 6 hrs/day Power = 30 Watts Usage = 8 hrs/day Power = 120 Watts Usage = 24 hrs/day Power = 500 Watts Usage = 4 hrs/day

  4. Chargers Power = 1100 Watts Usage = 15 min/day Power = 1100 Watts Usage = 15 min/day Power = 1100 Watts Usage = 15 min/day

  5. TTF Appliances Power = 150 Watts Usage = 6 hrs/day Power = 3000 Watts Usage = 8 hrs/day Power = 120 Watts Usage = 24 hrs/day

  6. TTF Appliances Power = 200 Watts Usage = 15 min/day Power = 10 Watts Usage = 15 min/day Power = 25 Watts Usage = 24 hrs/day Power = 15 Watts Usage = 8 hrs/day

  7. Try to Audit another room, like your living room! Make a list of the appliances and then Use this website to help you find the wattages. Think about how often and how long you use those items. Can you use less energy? How? http://www.wholesalesolar.com/StartHere/HowtoSaveEnergy/PowerTable.html

  8. Energy Scavenger Hunt Worksheet *1 kWh = 1 lb coal **1 lb coal = 1.4 lb CO2

  9. What is Power? • Power is the rate at which electric energy is transferred by an electric circuit • Power is measured in Watts • To calculate power: • V is voltage (pressure of electrons) • I is current (flow of electrons)

  10. Power vs. Energy • Using Less: • Energy efficiency (less W) • Energy conservation (less hrs)
