Problem 3: Emissions from Coal and Natural Gas Electricity (26 pts) 26 pts Questions 17-19: Read the information below and then answer the questions that follow. Put your final answer in BOLD and UNDERLINED font. Recent trends in electricity generation show a shift from coal to natural gas generation. In this problem, we will calculate the benefits of this switch for air quality and greenhouse gas emissions. 17. Look up the net generation of electricity from coal and natural gas for the years 2008 and 2016 on the EIA's Monthly Energy Review Data Browser (numbers are in million kWh). 17a. Use those values to fill out the following table: (6 pts) Source 2008 net generation (million kWh) 2016 net generation (million kWh) Change in generation (2008- 2016) (million kWh) 746,652.583 Decrease 495,326.335 Increase Coal 1,985,801.247 1,239,148.654 Natural Gas 882,980.599 1,378,306.934 17b. Given the information you have found, how much coal electricity has been displaced by natural gas electricity? (think carefully) (2 pts) In 2016 Natural Gas displaced Coal by 139,158.28 million kWh. 17c. Why is the decrease in coal generation not equal to the increase in natural gas generation? (2pts) 18. Given the shift from coal to natural gas generation that you calculated in #17 and the emission rates for air pollutants in the table below, calculate the savings (reductions) in SOX, NOx, mercury, and greenhouse gases (in metric tons) that can be attributed to that shift. (8 pts) Average Emissions from Coal and Natural Gas Power Plants (g/kWh) Coal Natural gas | | SOX INOX 1.814 0.862 0.005 | 0.168 MERCURY 1.48 x 105 0 GHG (CO2) 820 490 19. In 2008, the U.S. emitted 10,324,000 metric tons of SOx 16,909,000 metric tons of NOx, 61 metric tons of mercury and 7,145 million metric tons of CO2-e. Given your results from #18, what is the percent reduction for each of these emissions from 2008 to 2016 for the U.S. that is attributable to the shift from coal to natural gas generation in the electric sector?
