President Barack Obama signed the American Recovery and Reinvestment Act of 2009 on Tuesday and the measure includes US $16.8 billion for the DOE Office of Energy Efficiency and Renewable Energy (EERE). The funding is a nearly tenfold increase for EERE, which received $1.7 billion in fiscal year 2008.

The act also directs DOE to analyze the nation's electrical grid to determine if significant potential sources of renewable energy are locked out of the electrical market by a lack of adequate transmission capacity. DOE must then provide recommendations for achieving adequate transmission capacity.
