1 Yo u r Ca rbon Footprint Essential Q u e s tions How much energy do you use in a day? A month? A year? What is your carbon footprint, and how can you reduce it? Objectives Calculate how much electric energy you use in a day, a month, or year. Describe options to reduce the amount of energy you use. Identify ways to reduce your carbon footprint. D e l i ve rables (What You ll Turn In) Report (Must be typed) That Includes: Your Personal Energy Audit Data Table, completed (handwritten is acceptable) Your Carbon Footprint Calculation (handwritten is acceptable) A typed paragraph or two addressing each of the following topics. Carbon Footprint Describe what a carbon footprint is, and why it is an important metric for environmental protection. Summary of My Energy Usage A summary of your energy audit, comparing your values for energy consumption and carbon footprint to U.S. residential averages, and include your PIE CHART, showing your electric energy consumption. Reducing Our Footprint Research and report on at least two ways to reduce your carbon footprint be specific and realistic. Estimate how much each of these could reduce your footprint, and explain how you came up with your estimation. Offsetting Our Footprint Research and report on at least two ways you could offset your carbon footprint. Estimate how much each of these could reduce your footprint, and explain how you came up with your estimation. Sources Cite your sources, using MLA formatting. Background: Everyday, we plug in our phones, turn on the lights, listen to our stereos, wash our clothes, run the air conditioning, and pop our toast. Are you aware of where all that energy comes from? How much energy does your lifestyle really use? Although it is hard to see the energy, it is important to know that it has to be generated somewhere? The purpose of the carbon footprint calculation is to try and get a better understanding of how much energy you use over the course of a month. Carbon is a major by-product of energy use across the world and has many effects on the local and global environment and our health. This estimate of your personal carbon consumption and production is meant to provide a snapshot of exactly what a carbon footprint represents. You will conduct a Personal Energy Audit, and then use your results to complete this project.

2 Personal Energy Audit Instructions Record your personal energy usage for a one-day period. Use the supplied data chart. In order to be accurate, pay close attention to your energy use. If you are unsure of how often the microwave, A.C, heater, washing machine, dishwasher, etc. are used, please talk to your family members to use the best information. After recording the data for your one-day period find your total number of kilowatt-hours (kwh) of energy used in a day. Then, calculate your yearly totals. Assign each electric energy usage into one of the following categories: Appliances and Lighting Space Heating (not necessary if you use gas) Water Heating (not necessary if you use gas) Refrigeration Electric Air Conditioning In 2013, the average annual electricity consumption for a U.S. residential utility customer was 10,908 kilowatt-hours (kwh), according to MIT, the average American s carbon footprint is 20 metric tons (20000 kg) of carbon more than twice the global average. How does your consumption compare? You will include a brief description of these comparisons in your report. The pie chart shown above shows the distribution of electric energy consumption for an average U.S. residential utility customer. You will create a similar pie chart, based on YOUR findings. If you have questions about calculating percentages of the total, come find me (but you shouldn t). Your Carbon Footprint Calculations Research what is meant by the term Carbon Footprint. You will include a brief explanation of this in your report. Use your annual kwh usage to calculate your carbon footprint in pounds of carbon kg CO kwh 1kWh 2 kg CO kg 20 kg CO 2 = kg Carbon Reducing Your Carbon Footprint Research ways that you could reduce your carbon footprint. You will include a brief description of this in your report. Research ways that you could offset your carbon footprint. You will include a brief description of this in your report.
