Are insulated garage doors eligible to be an energy-efficient improvement?

[CynthiaR]

 Equipment that qualifies for the Residential Renewable Energy Tax Credit includes solar, wind, geothermal and fuel-cell technology:

• Solar panels, or photovoltaics, for generating electricity. The electricity must be used in the home.
• Solar-powered water heaters. The water heated by the system must be used inside the home, and at least half of the home's water-heating capacity must be solar. (Solar heaters for swimming pools and hot tubs do not qualify.)
• Wind turbines that generate up to 100 kilowatts of electricity for residential use.
• Geothermal heat pumps that meet federal Energy Star guidelines.
• Fuel cells that rely on a renewable resource (usually hydrogen) to generate power for a home. The equipment must generate at least 0.5 kilowatts of power.

So insulated garage doors would not be eligible.
