Basic Information
Human Energy Behaviors: Using Electricity
Over 98% is wasted !
EBulb= 5%
CO2
EW= ~ 50% ~50%%
EC= ~10%
Example:
Overall efficiency for conversion of fuel energy to lighting=
EPP x ET x EBulb = 1.6%
EPP= 0.35 ET= 0.90
What is a kWh?
Cost (PG&E)…. 11 – 44 cents
CO2 emissions (PG&E): 106 balloons
100 Watt 10 hours
A measure of electrical energy consumed
= 1000 Watt-hours
= 1 kiloWatt-hour = 1 kWh
Activity #1:Getting to Know Your
Electricity Bill
Electricity Bill1. Estimate weekly electricity
usage:
= total kWh / 4 weeks
2. Estimate weekly CO2 emissions:
= total kWh x 106 balloons / 4 wks.
3. Calculate weekly cost of electricity:
= total charges / 4 weeks
4. Compare to savings from “Observation Worksheet”
Activity #2:Hunting for Balloons &
Dollars
Daily Device Use Activity Worksheet
2. Fill-in the times when the devices are actually being used
3. Use an “X” to mark times when you are not using these devices
1. Use a horizontal line to mark times when devices are on in your household
