Unformatted text preview: 1. The U.S. Department of Energy (DOE) Energy Information Administration (EIA) produces an Annual Energy Review (see http://www.eia.doe.gov/emeu/aer/). Download the Excel file with the Electricity Net Generation: Total (All Sectors) data. [12 points] a) Plot the electricity generation for all the sectors versus time (1949-2006). Your graph should look similar to that below, except that there will be more sectors and more years. (Please don’t forget the fundamentals of engineering graphs: labels, units, etc.) b) For 2006: what were the five largest fuel sources for electricity, and what percentage of the total does each of these 5 sources represent? What is the total percentage from all 5 of these sources? Make a table like that below to record your answers. Solution: a) The raw data are from Table 8.2a of the Annual Energy Review, and they are plotted on the next page. You definitely should have a legend for the curves and units on the y-axis. b) In 2006, the five top fuel sources were 1. 2. 3. 4. 5. Five Largest Fuel Sources for Electricity in the U.S. for 2006 Coal Natural gas Nuclear Hydroelectric Petroleum Total : Fuel Source Percentage of Total Electricity Generation 49.0 % 19.9 % 19.4 % 7.1 % 1.56 % 97.0 % Hence, the first four sources provide most of our electricity in the U.S. U.S. Electricity Net Generation 2,500,000,000 1,500,000,000 1,000,000,000 Coal Nuclear Nat Gas 500,000,000 Nat Gas Hydro Hydro Petroleum Petroleum 0 Nuclear 19 49 19 51 19 53 19 55 19 57 19 59 19 61 19 63 19 65 19 67 19 69 19 71 19 73 19 75 19 77 19 79 19 81 19 83 19 85 19 87 19 89 19 91 19 93 19 95 19 97 19 99 20 01 20 03 20 05 Thousand Kilowatt-Hours 2,000,000,000 Coal 1 Natural Gas 3 Nuclear Electric Power Conventional Hydroelectric Power Petroleum 2 Other Gases 4 Hydro- electric Pumped Storage 5 Wood 6 Waste 7 Geo- thermal Solar 8 Wind -500,000,000 ...
