CHEM111 Lab Activity

Estimating your Annual Energy Consumption & Carbon Production

INSTRUCTIONS:

1. Open the Excel template “Lab1-PowerConsumption-Blank.xls” that was emailed to you earlier. Save a copy of this file for your records – give it a unique filename.

2. Begin filling in the ‘green’ areas of the template, using appropriate wattage values. You are welcome to add/delete rows from the spreadsheet so that it is customized to your household. If wattage data is missing, you are encouraged to consult appropriate internet resources to determine the power associated with those devices. The following website is particularly useful:

3. While you are working through the spreadsheet, your instructor will be circulating around and assisting you with certain problematic areas – such as determining the correct wattage/time combinations that translate into a valid estimation for central air conditioning-heating system, refrigerator, and hot water heater energy use.

4. Once you have completed the “Electrical Power Consumption, Cost Analysis, Carbon Count” portion of the spreadsheet, proceed on to the Automobile, Flying, and Dietary Carbon Count sections.

LAB REPORT (Answers to the following questions should be turned in by the beginning of next week’s lab. Email your final spreadsheet to your instructor at [email protected] ):

1. Indicate the annual tons of carbon dioxide that you or your household produce in each category:

a. Electricity Use: _____________________

b. Automobile Use: _____________________

c. Flying: _____________________

d. Dietary Preference: _____________________

2. Based upon the results of your analysis, which of the following actions would lead to less overall energy consumption in your household (circle the best answer)?

a. Reducing your lighting use by 75%.

b. Reducing your ‘cooking time’ by 50%.

c. Reducing your air conditioning/heating by 25%.

3. Appliances can vary on energy consumption with some models using more energy than others for the same work. Complete the below table.

Question: If you could only replace one appliance, which would provide greater savings to your household?

Appliance

Energy Usage

Watts

Yearly Energy Consumption

Yearly Cost

Conventional Clothes Dryer

(4 cu ft)

High

Low

Ventless Dryer

(4 Cu ft)

Oven

High

Low

Dishwasher

High

Low

4. Switching to more efficient and cost effective light bulbs is one way to save energy. Complete the following table to compare the energy savings of different lighting alternative.

Light source

Watt – Light Equivalence

Watts

Yearly Energy Consumption

Yearly Cost

Incandescent

100 Watt

40 Watt

Question: What is the most energy efficient option for each Watt-Light Equivalence? How much energy would you save by switching light sources in your home, but keeping the light equivalence the same?

5. In light of the results of your entire analysis, write a paragraph that summarizes an effective strategy for reducing your annual carbon emissions.
