Question
Carbon Footprint Assignment Please use the information below to answer questions 1 and 2. Show your work for full credit and upload your answers. 1 gallon of gas emits 8.9 kg of CO2 1 mile of flight produces 53 lbs of CO2 Use 28 miles per gallon for gas powered cars Use 0.436 kW per hour of use for electric cars Distance from Columbia, MO to San Diego, CA = 1,800 miles 1 kW = 0.81 lbs CO2 1 kg = 2.2 lbs LED bulb 10 Watts per hour Incandescent bulb 100 Watts per hour 365 days in a year Electric furnace uses 10 kW per hour. 1. You have an opportunity to go on a spring break trip to San Diego, California. Use the information above to evaluate the carbon impact of your travel. A. How many kg of CO2 will you produce flying? (5pts) B. How many kg of CO2 will you produce driving? (5pts) C. How Many kg of CO2 in an electric car? (5pts) D. What other factors am I leaving out that will affect your decision making? Be descriptive! (5pts) 2. You live in a small apartment with an electric furnace. Use the information above to answer the following questions. A. How many kg of CO2 will you save over a year by switching your 4 lamps from incandescent to LED bulbs. Your lights are on for an average of 4 hours a day. (5pts) B. How many kg of CO2 will you save over a year by reducing your thermostat from 70 to 68 degrees over 4 winter months (120 days)? Your furnace is using power for 6 hours a day at 70 degrees and 4 hours a day at 68 degrees. (5pts) C. What are other major decisions to consider when it comes to home energy saving to reduce CO2 impact? Why does it matter which energy source your electricity comes from? If a power plant burns only coal over only natural gas, would your pounds of CO2 per Kw go up or down? (5pts)
