Tax subsidies that are energy-specific, but can be used for multiple types of energy, include the following items:
- Alternative fuel production credit
- Energy production credit (sec 45)
- Advanced energy property credit
- Exceptions for publicly traded partnership with qualified income derived from certain energy-related activities
The largest of these multi-use incentives is the Energy Production Tax Credit (PTC) which provides a tax credit ranging from 1.1 cents per kilowatt hour to 2.3 cents per kilowatt hour for the production of the following types of energy: wind, closed and open loop biomass, geothermal, landfill gas, trash, qualified hydropower, and marine and hydrokinetic power. The PTC also provides $7.47 per ton on the sale of qualified refined coal, and $2.27 per ton on the sale of Indian coal.
Of the $5 billion spent on the PTC in the last four fiscal years, the majority has been claimed by wind properties.
Overall, for Fiscal Years 2009 through 2012, multi-use tax subsidies accounted for 16 percent of total tax subsidies for energy.
