108 <br /> each type of fuel to the total number of households in the entire state using the same fuel <br /> type. In Orange County, 6,078 households use bottled, tank, or LP gas, and 445 use fuel <br /> oil, kerosene,or similarfuels.Statewide,256,257 households use bottled,tank,or LP gas, <br /> and 91,569 use fuel oil, kerosene, etc. The proportion of households in Orange County <br /> using bottled, tank, or LP gas is 0.0237, while the proportion using fuel oil, kerosene, <br /> etc., is 0.0486. To calculate the County's share of energy consumption, we multiply <br /> these proportions by the statewide energy use. According to data from the US Energy <br /> Information Administration 20 North Carolina consumes 17.6 trillion Btu of Hydrocarbon <br /> Gas Liquids (HGL, which includes LPG) and 4.1 trillion Btu of Distillate Fuel Oil. After <br /> converting these figures from trillion Btu to MMBtu and applying Orange County's <br /> proportions, we estimate that the County's consumption of LPG is 417,443 MMBtu and <br /> its consumption of Distillate Fuel Oil #2 is 19,925 MMBtu.These estimates are calculated <br /> to carbon equivalencies using the US Community Protocol in ICLEI, applying emission <br /> factors of 62.98 kg/MMBtu for CO2, 0.01087 kg/MMBtu for CH4, and 0.0010870 kg/ <br /> MMBtu for N20. <br /> COAL <br /> Emissions data from the coal cogeneration boilers at the University of North Carolina <br /> at Chapel Hill are sourced from the 2018 Annual Air Emissions Inventory Cogeneration <br /> Facility report, prepared by ClimeCo Corporation in 2019.21 Detailed information about <br /> emissions from Boiler 6 can be found on pages 31-33, while Boiler 7's emissions are <br /> documented on pages 54-56. <br /> TRANSPORTATION AND MOBILE SERVICE <br /> Transportation emissions in Orange County were computed using the Google EIE <br /> transportation data,22 a source recommended by ICLEI. The emissions factors are <br /> sourced from the US Community Protoco1,23 which are as follows: <br /> CO2 Emissions Factor 0.07024 <br /> CO2 Emissions Factor Units MT/MMBtu <br /> CH4 Emissions Factor 1.9493 x 10-$ <br /> CH4 Emissions Factor Units MT/mile <br /> N20 Emissions Factor 1.0608 x 10-$ <br /> N20 Emissions Factor Units MT/mile <br /> 20 https://www.eia.gov/state/search <br /> 21 2018 Annual Air Emissions Inventory Cogeneration Facility.The University of North Carolina at Chapel <br /> Hill:Chapel Hill,North Carolina <br /> 22 https://insights.sustainability.google/places/ChIJEejT22XdrlkRPupCdcVJtOk?hl=en-US <br /> 23 U.S.Community Protocol for Accounting and Reporting of Greenhouse Gas Emissions Appendix D: <br /> Transportation and Other Mobile Emission Activities and Sources <br /> 17 ORANGE COUNTY, NC • APPENDICES <br />
