Section 45 of the Internal Revenue Code allows an income tax credit of 2.3 cents/kilowatt-hour (as adjusted for inflation for 2013) for the production of electricity from utility-scale wind turbines, geothermal, solar, hydropower, biomass and marine and hydrokinetic renewable energy plants. This incentive, the renewable energy Production Tax Credit (PTC), was created under the Energy Policy Act of 1992 (at the value of 1.5 cents/kilowatt-hour, which has since been adjusted annually for inflation). In late 2015 a large majority in Congress voted to extend the PTC for wind and solar power for 5 years and $25 billion. Analysts expect $35 billon of investment for each type.
