The Museum of Aviation says it is saving money by using green energy, which is also contributing to national Department of Defense goals to use more renewable sources.
Since 2009, the main building of the museum has been using the renewable source, but as of the beginning of May, the whole facility will be using it.
It's part of a cooperation with Flint Energies, who gets the energy in part from the Houston County landfill.
The landfill takes trash and compacts it. They then collect the methane gas through wells and burn it into green energy.
Flint says it ends up costing the Air Force less because the landfill system costs less to produce.
The museum uses 2.4 million kilowatt hours per year.
