• How much energy and
water does it take to wash my clothes?
• How much energy and water could I conserve if I laundered a different way?
• What technologies and technique are out there to conserve water and energy when laundering?
Question:
![Page 3: Energyproject](https://reader034.fdocuments.in/reader034/viewer/2022052619/55692d13d8b42add468b49ea/html5/thumbnails/3.jpg)
• Over a two week period I collected data on my use of the washer and drier machine.
• Next I took my consumption and converted my use into kWh used and gallons of water consumed.
• To conclude I compared my consumption to what I could could have saved using alternative methods of laundering.
Methodology:
![Page 4: Energyproject](https://reader034.fdocuments.in/reader034/viewer/2022052619/55692d13d8b42add468b49ea/html5/thumbnails/4.jpg)
Data Collection:• I collected data on the number of washer and drier times over the coarse of two weeks. • I use a standard Kenmore washer machine and drier that consumes 40 gallons and ~4 kWh per wash, and drier that consumes 4 kWh per 45 min at standard temperature.
• I also collected data on the settings I used to wash and dry and accounted for it in my estimation of the energy and water consumed.

• Energy consumption in kWh was estimated through research not actual gauging.• Could not account for change in size of loads even though I used the same setting every time.• My laundering use is probably not constant all year around, even though I assumed that in my annual projections.
Experimental Errors:

What If? Alternatives to my current
consumptions trends.• I could save energy by non-machine drying my clothes. (543.84 kWh/year)
• Hand washing my clothes. (508.8 kWh/year)
• Using cold settings on the washer machine. (103 kWh/year Vs ~500 kWh/year on regular settings)
• Use a side loading machine (~50% water savings)

“Wrapping Things Up”Project Conclusions:
* Using the heat that is already generated in side my house can be used to dry my clothes via drying
racks
* Hand washing or using cold settings on the washer machine can save a lot
of electricity

• Clothes lines
• Drying racks
• Hand washing
• Front loader washer machines are more efficient.
• Only wash what you need washed.
• Use cold wash or at least cold rinse to save energy.
