Energy In Brief Articles
Greenhouse gases trap heat from the sun and warm the planet's surface. Of U.S. greenhouse gas emissions, 87% are related to energy consumption. Since 1990, greenhouse gas emissions in the United States have grown by about 1% per year.
Energy and the Environment Explained
Levels of several important greenhouse gases have increased by about 40% since large-scale industrialization began around 150 years ago. During the past 20 years, about three-quarters of human-caused emissions came from burning fossil fuels. Concentrations of carbon dioxide in the atmosphere are naturally regulated by numerous processes collectively known as the "carbon cycle."
In the United States, greenhouse gas emissions come primarily from the burning of fossil fuels in energy use. Energy use is largely driven by economic growth with short-term fluctuations in its growth rate created by weather patterns affecting heating and cooling needs. Energy use is also driven by changes in the fuel used in electricity generation.

These estimates of energy-related carbon dioxide (CO2) are based on the States Energy Data System. The state data include a summary table with total energy-related CO2 by state beginning in 1990, a table with emissions by fuel in 2010 and a table with emissions by sector in 2010. Detailed tables for individual states provide emissions by fuel and sector for data beginning in 1980.

This online analysis of 2011 energy-related carbon dioxide emissions indicates U.S. carbon dioxide emissions from the consumptiion of fossil fuels were 5,471 million metric tons carbon dioxide (MMTCO2) in 2011, a decrease of 2.4 percent from the 2010 level.
