MO SB602

Establishes the "Capital Green Program" to fund weatherization and energy efficiency improvements to the Missouri state capitol building and governor's mansion.

Authorizes exploration and installation of geothermal, wind, and solar energy pilot programs, including free-flow turbine generators in the Missouri River to power the capitol building and governor's mansion, with surplus energy available for the Harry S Truman office building, Missouri supreme court building, and James C. Kirkpatrick state information center.

Creates the "Capital Green Program Fund" as a dedicated fund in the state treasury, funded by general assembly appropriations from general revenue and private gifts, bequests, or donations.

Allows fund balances to carry over between fiscal years without reverting to general revenue, with interest and investment earnings credited back to the fund.

Program automatically sunsets six years after enactment unless reauthorized by the general assembly, with a 12-year sunset period if reauthorized.
