Changes from previous AEO2010

  • Significant update of the technically recoverable U.S. shale gas resources, more than doubling the volume of shale gas resources assumed in AEO2010, and also added new shale oil resources
  • Revision of the methodology for determining natural gas prices to better reflect a lessening of the influence of oil prices on natural gas prices, in part because of the increase in shale gas supply and improvements in natural gas extraction technologies
  • Update of the data and assumptions for off shore oil and gas production, pushing out the start of production for a number of projects as a result of the six-month drilling moratoria, and delaying Atlantic and Pacific off shore leasing beyond 2017

Updates from Early Release Reference case

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:

  • Adds 30% ITC to fuel cells with 2016 expiration date
  • Retired Oyster Creek nuclear plant at end of 2019
  • Revised amount of wind builds in 2012 (7 rather than 10 gigawatts)

Executive Summary

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 (see Appendix E, Table E1), which explore important areas of uncertainty for markets, technologies, and policies in the U.S. energy economy.

Key results highlighted in AEO2011 include...
