Annual Energy Outlook Report
The Annual Energy Outlook 2011 (AEO2011) Reference case that is included as part of the complete report released in April, 2011 has been updated from the Reference case that was released as part of the AEO2011 Early Release Overview in December, 2010. The Reference case was updated to incorporate modeling changes and reflect new legislation or regulation that was not available when the Early Release Overview version of the Reference case was published. Major changes made in the Reference include:
The projections in the Energy Information Administration's (EIA) Annual Energy Outlook 2011 (AEO2011) focus on the factors that shape the U.S. energy system over the long term. Under the assumption that current laws and regulations remain unchanged throughout the projections, the AEO2011 Reference case provides the basis for examination and discussion of energy production, consumption, technology, and market trends and the direction they may take in the future. It also serves as a starting point for analysis of potential changes in energy policies. But AEO2011 is not limited to the Reference case. It also includes 57 sensitivity cases, which explore important areas of uncertainty for markets, technologies, and policies in the U.S. energy economy.
