Energy Audit Lab
Data
1. Obtain a copy of your electricity bill. Calculate the average daily cost for electricity in your house. $5.38
2. After calculating the daily electricity usage (in Table 1), average out the cost per kWh. If it is indicated on your electricity bill, how does your estimate compare?
Estimate- 16.6/60(minutes in an hour)= .28; my estimate is .16 cents more from the actual cost per kWh.
3. In order to determine the amount of CO2 released by your electricity consumption each month, multiply the number of kilowatt-hours used per month by the kilograms of CO2 produced per kWh (see table 3 below). If a coal-burning power plant is the main source for your electricity, the amount of SO2 emitted per month can be approximated by multiplying the number of kilowatt-hours used per month by kilograms of SO2/kWh. Consult your local power utility to determine the fuel mix used to generate electricity in your area. (If coal or oil is used, determine the amount of SO2 produced.)
Our energy comes from Coal.
carbon dioxide emitted= 840(0.97)= 814.8 kg/kwh
sulphur dioxide: emitted= 840(0.006)=kg/kwh
4.Compare a utility bill from a summer month with one for March or April. Estimate what amount of the summertime bill is due to air-conditioner use.
The bill during summer was $117.01. I think that about a quarter of the bill was due to the AC.
5. Inspect and report on the following for your home:
a. The amount, location and quality (type and R-value) of insulation: Our insulation is fiberglass and it is used on all windows and our R-value is R-11.
b. The amount of shade provided by trees or shrubs: Great amount
c. The condition, composition, and color of the roof: Rusty, metal, and Silver
d. The air circulation in the attic: No attic
e. The tightness of the fit for doors and windows: Not well tightened
f. The color of outer walls (does it absorb or reflect heat?): The walls inside the house are colored Orange and it absorbs heat. The outside walls are blue and they reflect heat.
g. Any other features that may affect the dwelling’s heat balance: It is old and it is trailer.

The Report
In this project i have learned why the electricity bill for us is high. My household members and I have learned that we leave things on that we don't need to be turned on, and if we turn off those things, the electricity bill for us will be lower than usual. If my household members didn't use the washer or dryer as much during the week, we would probably save around $10-$20 per month. We should also watch the time we spend on the TV set or the computer too. Not using these things as much as we do, we would burn less coal and fossil fuels that destroy the Earth. Things that could help the environment are products that are energy star approved. The only disadvantage about this is that some of those products are more expensive than other products. This would make us spend a lot of money on energy star products, but this would benefit the Earth, which we need to live, and your future electricity bills will not be as expensive as before because it burns less fossil fuels, and soon our payment for the electricity bills will give us back our money because we won't pay as much as before.
