in a Natural Disaster
By Andrea Stasyszen
Essential Question
How much electricity do my “heavy weight” appliances use and will limiting
their use effectivelyLOWER MY BILL?
Research
1)KWH usage prior to the natural disaster2)KWH usage:

Summarized Results
Normal usage, bill would have been $527.35
By using conservation, my bill was $474.87
= Savings of $ 52.48
The Big Picture
AEL&P customers consume 293 million Kwh annually
If 14,500 customers conserved 15%, near 44 million Kwh saved
Based on 2008 current rates, that is a savings to Juneau of $4,620,000.
Conclusion
Limiting or cutting out heavy weight appliance effectively lowered my bill and energy
usage in an electrical crisis by 12-33%.
Long Term Conclusion
