1. Energy Audit

2. Energy Audit Worksheet Guide
List all the appliances in your house
Go room by room (kitchen, living spaces/den, bedrooms, bathrooms, laundry, garage, take a walk outside, etc)
Count the number of units or each appliance
Research the wattage of each appliance

3. Energy Audit WS Guide Cont.
Calculate the estimated use in hours per month
Appliance
# of units
Watts
Hrs/mo
watthours
Fridge 2 X
600
150 =
180,000
Fridge runs ~5hrs/day x30=150 hrs/mo
hairdryer 1
1000 x
2000
10min/day x 3days/wk= min/wk x 4wks = min/mo /60min = 2hrs/mo
1 mo = 30 days

4. Energy Audit WS Guide Cont.
Multiply # of units x wattage x hours/mo to find the Watthours (Wh) / month
To find the kiloWatt hours (kWh), divide the Wh by 1000
Use 8.5 cents (0.085) for the price per kWh

5. Calculate Energy Savings
Research your ‘big’ wattage appliances to find ones that use less watts.
On separate sheet, make a table with the energy efficient wattage for each new appliance.
Research the price for materials and labor / install for the new appliances.
Complete the energy savings WS
Hint on next slide converting help

6. Converting Help I have kWh/yr and need to find Watts
kWhr/yr divided by 12mo  kWhr/mo
kWhr/mo times 1000w  Whr/mo
Whr/mo divided by 30 days  Watts per day

7. Write about your savings
The research is complete, it’s time to write
Claim – Evidence – Reason LETTER to your parents
1 Conceptual claim about energy efficiency
3 detailed pieces of evidence (evidence = appliances) (multiple sentences for each piece of evidence)
1 AMAZING scientific reason that will convince your parents to change / switch appliances
