Devon Siegel – das257 Assignment 5: Global Processes 1. In 1999, the U.S. Department of Energy (DOE) in conjunction with the U.S. Environmental Protection Agency (EPA) and the Energy Information Administration (EIA) produced a report which outlined the specific factors behind CO2 emissions in the United States. In the report, it was estimated that CO2 emissions ensuing from the generation of electricity reached 2,245 million metric tons; a dramatic increase of 1.4 percent (30 million metric tons!) from the previous year. What accounts for this increase? What can be done to avoid further increases in CO2 emissions from the U.S, specifically from the generation of electricity? The increase in carbon dioxide emissions can be attributed to increased demand for electricity, the types of fuel/energy sources used for electricity generation and the thermal efficiencies of power plants. Underlying factors that influence the primary sources of increased carbon dioxide emission are economic growth, the price of electricity, the amount of imported electricity, weather, fuel prices, and the amount of available generation from other sources. economic growth, the price of electricity, the amount of imported electricity, weather, fuel prices, and the amount of available generation from hydroelectric, renewable, and nuclear plants. There are a handful of things that can be done to avoid further increase in carbon dioxide emissions from the United States. First, non-fossil fuels and renewable energy sources can be used. Second, demand-side management actions such as replacing light bulbs and appliances with more energy-efficient models and improving insulation technologies can reduce demand. The reduction in demand directly corresponds to a reduction in emissions.
