EGEE 102 - Pisupati EGEE 102 - Energy Conservation and Environmnetal Protection (EGEE 102) 6. Global Warming Global Warming Greenhouse Gases Carbon dioxide combustion of solid waste, fossil fuels (oil, natural gas, and coal), and wood and wood products Methane : production and transport of coal, natural gas, and oil. Methane emissions also result from the decomposition of organic wastes in municipal solid waste landfills, and the raising of livestock. Nitrous oxide agricultural and industrial activities, as well as during combustion of solid waste and fossil fuels. hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), industrial processes. Temperature Changes GHG Emissions Increase Since pre-industrial times atmospheric concentrations of CO2, CH4 and N2O have climbed by over 31%, 151% and 17%, respectively. Scientists have confirmed this is primarily due to human activity. Burning coal, oil and gas, and cutting down forests are largely responsible. Global Warming Cut your utility bills by purchasing energy-efficient appliances, fixtures, and other home equipment and products. The average house is responsible for more air pollution and carbon dioxide emissions than is the average car. Global Warming Potential Role of Energy Emissions By Sector Greenhouse Gas Emissions Individual Emissions In the United States, approximately 6.6 tons (almost 15,000 pounds carbon equivalent) of greenhouse gases are emitted per person every year. And emissions per person have increased about 3.4% between 1990 and 1997. Most of these emissions, about 82%, are from burning fossil fuels to generate electricity and power our cars.
