(This measure has not been amended since it was reported to the House on September 8, 2009. The summary of that version is repeated here.)

Wind Energy Research and Development Act of 2009 - Directs the Secretary of Energy to carry out a research and development program to: (1) improve the energy efficiency, reliability, and capacity of wind turbines; (2) optimize the design and adaptability of wind energy systems to the broadest practical range of atmospheric conditions; and (3) reduce the cost of construction, generation, and maintenance of such systems.

Directs the Secretary to conduct a wind energy demonstration program to measure wind energy system performance under the full productive range of wind conditions in the United States.

Requires awards under such programs to be made on a competitive basis with an emphasis on technical merit.

Requires the Secretary, in carrying out this Act, to: (1) coordinate with the Office of Minority Economic Impact and with the Office of Small and Disadvantaged Business Utilization; and (2) provide special consideration to applications submitted by institutions, businesses, or entities containing majority representation of women, minorities, or persons with disabilities in science and engineering.

Authorizes appropriations.

Wind Energy Research and Development Act of 2009 - Directs the Secretary of Energy to carry out a research and development program to: (1) improve the energy efficiency, reliability, and capacity of wind turbines; (2) optimize the design and adaptability of wind energy systems to the broadest practical range of atmospheric conditions; and (3) reduce the cost of construction, generation, and maintenance of wind energy systems.

Requires the program to focus on research and development of specified areas, including: (1) new materials and designs to make larger, lighter, less expensive, and more reliable rotor blades; (2) technologies to improve gearbox performance and reliability; (3) automation, materials, and assembly of large-scale components to reduce manufacturing costs; (4) advanced generators; (5) wind technology for offshore applications; (6) methods to assess and mitigate the effects of wind energy systems on radar and electromagnetic fields; and (7) wind turbines with a maximum electric power production capacity of 100 kilowatts or less.

Directs the Secretary to conduct a wind energy demonstration program that: (1) is of sufficient size to measure wind energy system performance under the full productive range of wind conditions in the United States; and (2) includes demonstration projects conducted in collaboration with industry that yield data that is useful for the research and development program. Requires the Secretary to carry out such demonstration program in compliance with provisions of the Energy Policy Act of 2005 regarding cost sharing and merit review of proposals.
