the repository required by subsection (a) is accessible through an 
Internet website of the Department of Defense and by all employees of 
the Department and members of the Armed Forces whom the Secretary 
determines appropriate, including all program managers involved in such 
research and development efforts, to enable improved collaboration 
between military departments on research and development efforts 
described in subsection (a), enable sharing of best practices and 
lessons learned relating to such efforts, and reduce redundancy in such 
efforts.

SEC. 4. SECURE ENERGY INNOVATION PROGRAM.

    (a) In General.--The Secretary of Defense shall conduct a program 
to develop and support projects designed to foster secure and reliable 
sources of energy for military installations, including incorporation 
of advanced energy metering, renewable energy, energy storage, and 
redundant power systems.
    (b) Metrics.--The Secretary of Defense shall develop metrics for 
assessing the costs and benefits associated with secure energy projects 
proposed or implemented as part of the program conducted under 
subsection (a). The metrics shall take into account financial and 
operational costs associated with sustained losses of power resulting 
from natural disasters or attacks that damage electrical grids serving 
military installations.

SEC. 5. AUTHORITY TO USE ENERGY SAVINGS INVESTMENT FUND FOR ENERGY 
              MANAGEMENT INITIATIVES.

    Section 2919(b)(2) of title 10, United States Code, is amended by 
striking ``, to the extent provided for in an appropriations Act,''.

SEC. 6. ESTABLISHMENT OF DEPARTMENT OF DEFENSE ALTERNATIVE FUELED 
              VEHICLE INFRASTRUCTURE FUND.

    (a) Establishment of Fund.--There is established in the Treasury a 
fund to be known as the ``Department of Defense Alternative Fuel 
Vehicle Infrastructure Fund''.
    (b) Deposits.--The Fund shall consist of the following:
            (1) Amounts appropriated to the Fund.

United States Government, or an obligation that has its principal and 
interest guaranteed by the Government, that the Secretary decides has a 
maturity suitable for the Fund.
    (d) Use of Funds.--Amounts in the Fund shall be available to the 
Secretary, acting through the Under Secretary of Defense for 
Acquisition, Training, and Logistics, to install, operate, and maintain 
alternative fuel dispensing stations for use by alternative fueled 
vehicles of the Department of Defense and other infrastructure 
necessary to fuel alternative fueled vehicles of the Department.
    (e) Definitions.--In this section:
            (1) Alternative fuel.--The term ``alternative fuel'' has 
        the meaning given such term in section 32901 of title 49,

        fuel.
            (3) Fund.--The term ``Fund'' means the fund established 
        under subsection (a).

SEC. 7. STUDY ON POWER STORAGE CAPACITY REQUIREMENT.
