### An Updated Annual Energy Outlook 2009 Reference Case Reflecting Provisions of the            American Recovery and Reinvestment Act and Recent Changes in the Economic Outlook

| Notes 

1 Several other  changes including updates to near-term world oil prices, reinstatement of the  Clean Air             Interstate Rule, and final action on Corporate Average Fuel Economy  standards for model year 2011 were also incorporated. 

2 For example, ARRA provisions to spur the use of  renewable energy, including a 3-year extension of the production tax credit for  eligible renewables, are important enough to impact the analysis of proposals  for a renewable  electricity standard.

3 The comparison  is only a rough approximation, for reasons discussed below in the section on macroeconomic  assumptions.
