Carbon dioxide emissions are one of the largest contributors to air pollution and climate change and the United States is responsible for the largest per capita emissions of carbon dioxide in the atmosphere. The main carbon emission sources in the U.S. are electricity production and power plant operations. It is necessary to regulate the direct sources of carbon dioxide emissions in order to prevent further irreversible damage to our environment and society. It is time for our nation’s carbon emissions to drastically decline in order to prevent dramatic climate events and destruction to our living environment.
The United States has about 6,000 electricity generating power plants, most of which are coal fired and emit a significant amount of carbon dioxide into the atmosphere. These power plants alone account for 41% of the total U.S. carbon emissions. A report by Environment America which ranked the top 100 dirtiest power plants in America, states that about half of those carbon emissions come from the 100 dirtiest power plants. The top 50 dirtiest plants alone produced 30 percent of all power-sector carbon dioxide emissions, but only generated 16 percent of electricity nationwide in 2011, which illustrates the urgency to increase efficiency. The report also states that if the top 50 dirtiest power plants in the United States created their own country, it would qualify as the seventh-biggest polluter in the world. That is just a small fraction of the power plants currently operating in our country. A main reason these coal power plants in the U.S. are exceptionally dirty is because until recently, there have been no federal policies in place to put limits on emissions.
