APES 5.06 Energy Conservation Worksheet

5.06 Energy conservation worksheet Instructions: For this assignment, you will complete a personal energy audit, by calculating the amount of electricity you use in a year. Then, you will convert your energy use to the equivalent energy resources to determine your personal impact on energy resources and the environment. Lastly, you will calculate the financial costs of your energy use. Submit your worksheet to your instructor when completed. Student Name: Maria Masselli title: Conserve Energy: Preserve Life Objective: ●​ Figure out my personal usage of energy and calculate the total electricity I spend in a year ●​ Convert energy use to the equivalent energy resources to determine my impact on energy resources and the environment. ●​ Calculate the financial costs of your energy use. ​ Procedure Part 1: Unless Otherwise Noted All Content © 2024 Florida Virtual School.

Use the Appliance Energy Reference Chart (Figure 1) to select 15 appliances you or your family use regularly. If you choose an appliance that is not listed, you will have to research how much power (watts) the appliance uses. 2. Record the 15 appliances you chose and the corresponding power (watts) for each in the first two columns of Data Table 1. Be sure to consider all appliances of one type. For example, count all lightbulbs in your home and multiply that number by the number of watts used by a lightbulb. If you have 10 lightbulbs in your house and each uses 65 watts, you should record 650 in Column 2. 3. Follow the directions above Data Table 1 to complete columns 3-8. Instructions for Columns 3-7 of Data Table 1: · Column 3 – Convert watts to kilowatts. · Column 4 – Estimate the number of hours used per day. · Column 5 – Multiply power (kilowatts) by estimated hours per day. · Column 6 – Estimate the number of days used per year. · Column 7 – Multiply energy per day (kilowatts hours) by estimated days per year. · Column 8 - In the last row of the chart, calculate the total energy (kilowatt hours) used per year for all appliances. Then, divide the energy per year (kilowatt hours) for each individual appliance by the total energy (kilowatt hours) used per year for all appliances. Multiply that answer by 100 to get the % of the Total. Figure 1.

Convert your yearly energy (kilowatt hours) use from Data Table 1 to British thermal units (Btus) using the following conversion factor. Record your total energy use in Btu on the line. CONVERSION FACTOR​ 1 kilowatt hour (kwh) = 3,412 Btu​ ​ Total Energy Use per year in Btu = 430,087,233 Btu. 2. Calculate the amount of coal, natural gas, oil, and uranium required to meet your energy needs yearly. Use the following conversion factors. Place these values in Data Table 2. CONVERSION FACTORS 1 pound of bituminous coal = 12,000 Btu​ 1 cubic foot of natural gas = 1,028 Btu 1 barrel of oil = 5,800,000 Btu​ 1 gram uranium = 4 x 107 Btu 3. Calculate how much each energy source will cost you per year for energy use. Use the conversion factors below. Place these values in Data Table 2. CONVERSION FACTORS Coal costs about $25 per ton Oil costs about $90 per barrel Natural gas costs about $5 per 1000 cubic feet Uranium costs about 2 cents per gram 2,000 pounds = 1 ton Table two: Energy source amounts and costs per year Energy Source Amount Needed Total Cost Unless Otherwise Noted All Content © 2024 Florida Virtual School.

Coal Pounds needed: 35,840,602.8 448,007.535 Natural Gas Cubic feet needed: 418,372.795 2091.8 Oil Barrels needed: 74.15 6664.5 Uranium Grams needed: 10.75 0.215 Graph: Using the graphing tools of your document, create one pie chart that shows the percentage each appliance contributes to the total percentage of yearly energy use. (To make the categories easier to see in your pie chart, group appliances together by type, such as heating and cooling or computer/electronics.) Reflection Questions: Answer the reflection questions, using what you have learned from the lesson and your data. It will be helpful to refer to your class notes. Answer questions in complete sentences. Unless Otherwise Noted All Content © 2024 Florida Virtual School. FlexPoint Education Cloud™ is a trademark of Florida Virtual School. 1.​ Compare your yearly energy use pie chart to the pie chart of home energy use presented in the lesson. Explain the differences or similarities between the charts. The difference between the charts is that the microwave takes up more energy than in the chart provided before. The same thing in common, though, is that most of the energy goes to the cooling and heating throughout the year in our houses. 2.​ Explain why the cheapest fuel is not the best choice for the environment. Having cheaper fuel makes more people want to drive more, which severely provokes more air pollution, harming the environment with the release of greenhouse gases. 3.​ Describe five methods from the lesson that could reduce your energy usage. One method to reduce my energy usage is to unplug devices that are not being used at the moment. Another method is to adjust the thermostats on the water in the washer. Thirdly, using less gas-based transportation methods and replacing them with bikes or walking. Moreover, adjusting the thermostat to reduce the use of heat and air conditioning. Lastly, conserving water is an efficient way to lower my energy usage, making my part in protecting the environment. Conclusion: Include a conclusion that is detailed in terms of accurately describing the lab and any conclusions drawn supported by data. Generally, this section will include a summary and interpretation of the lab results and data. Any experimental errors should also be reported and analyzed. Also, discuss what things you can do to investigate or apply these concepts further. After completing this lab, I have learned how much energy I use in a year throughout my house and how to reshape that. I should definitely work to better save on costs and pollution as my family and I massively rely upon the use of AC, which is drastically higher than the table provided, so we should definitely reflect and make less and efficient use of energy in a more eco-friendly way. I can further investigate my usage of energy by including more appliances in my observations to possess a more accurate scale of the impact of my energy use. *Submit this document on your 5.06 assessment.
