Representative Representative Peter Visclosky Chairman Ranking Democratic Member Subcommittee on Energy and Water Development Subcommittee on Energy and Water and Rayburn House Office Building, 2362‐B Development Washington, DC 20515 Rayburn House Office Building, 2362‐B Washington, DC 20515

Dear Representatives Boehner, Pelosi, Rogers, Dicks, Frelinghuysen, and Visclosky:

As the Full House Committee on Appropriations considers funding for the FY2012 Energy and Water Appropriations bill, the undersigned organizations urge support for continuing funding for Advanced Research Projects Agency – Energy (ARPA‐E) at a level equal to at least the FY 2011 funding level of $180 million.

ARPA‐E is conducting critical research necessary to ensure the nation’s future energy security. Modeled after the highly successful Defense Advanced Projects Research Agency (DARPA), ARPA‐E supports “high‐risk, high‐reward” research that private industry does not sufficiently invest in, but which has the potential to drastically alter how we acquire energy in the future. ARPA‐E is also helping to shape the next generation of energy researchers, attracting the nation’s best and brightest young minds to its opportunities. The enthusiasm for ARPA‐E’s vision was clearly demonstrated when its inaugural funding opportunity announcement resulted in an unprecedented 3,600 applications

Since 2009, ARPA‐E has awarded $363 million in projects, and is currently funding more than 120 projects. At least six of these projects have leveraged $23.6 million in federal funding into more than $100 million in private capital investment. Stable and sustained funding at the FY11 level is critical to ensure ARPA‐E’s continued success in ensuring U.S. competitiveness in the energy field and our nation’s future national security.

Sincerely,

A123 Systems, Inc. Alloy Ventures Advanced Technology Ventures American Chemical Society
