Abram Balloga Lesson 5 Assignment 1 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 CO 2 emissions in the United States. In the report, it was estimated that CO 2 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? From Source: http://blackboard.cornell.edu/webapps/portal/frameset.jsp? The factors which most heavily influence CO2 emissions from electricity generation from year to year are the growth in demand for electricity, the type of fuels or energy sources used for generation, and the thermal efficiencies of the power plants. A number of contributing factors influencing the primary factors can also be identified: 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. Other contributing factors include demand-side management programs that encourage energy efficiency, strategies to control other air emissions to comply with the requirements for the Clean Air Act Amendments of 1990, and the installation of new capacity utilizing advanced technologies to increase plant efficiency, such as combined-cycle plants and combined heat and power projects. The increase in 1999 can be most strongly contributed to increased consumption of electricity. With over a 4% growth in GDP and sharp decreases in electricity costs, the country was richer while energy became cheaper. So people used electricity more lavishly. Also, record high summer 1999 temperatures increased the demand for air conditioning, which in turn causes more output. What can be done to avoid further increases in CO 2 emissions from the U.S, specifically from the generation of electricity? Almost all of the major contributing factors can be combated in some way. But the most obvious and practical solution is increasing thegeneration from non fossil fuel sources like
