Fact check: Does nearly 40 percent of Iowa's electricity come from wind?

Wind farm in Iowa
Secretary of Energy Rick Perry ordered a review of the impacts of renewable energy policies on the reliability of the electric grid, and the results are due within a week.[1][2] In reporting on Perry’s directive in the Daily Caller, Michael Bastasch cited critics, including Sen. Chuck Grassley (R-Iowa), and noted that “Iowa gets nearly 40 percent of its electricity from wind turbines.”[3]
Does Iowa get nearly 40 percent of its electricity from wind turbines?
Yes. In 2016, 36.6 percent of Iowa's electricity was generated from wind power, according to the U.S. Energy Information Administration. Coal is the primary fuel used for electricity generation in the state.[4]
Background
In calling for the review, Perry instructed his staff to explore "[t]he extent to which continued regulatory burdens, as well as mandates and tax and subsidy policies, are responsible for forcing the premature retirement of base load power plants." (The term base load in this context refers to non-variable, or constant, sources of electricity generation such as coal, natural gas, and petroleum.) According to Perry, “[G]rid experts have expressed concerns about the erosion of critical base load resources … This has resulted in part from regulatory burdens introduced by previous administrations that were designed to decrease coal-fired power generation.”[1]
In response, representatives of the renewable energy industry, including the American Wind Energy Association, challenged Perry’s suggestion that wind and solar energy are unreliable and called for public input before the study results are used to set policy.[5][6]
Sen. Grassley also wrote to Perry criticizing his order, characterizing it as hastily developed and saying that it “appears to pre-determine that variable, renewable sources such as wind have undermined grid reliability."[7]
Wind energy regulations and tax credits
In 1983, Iowa became the first state to institute a Renewable Portfolio Standard (RPS). Iowa's RPS dictates that the state's investor-owned utilities (MidAmerican Energy and Alliant Energy Interstate Power and Light) must contract for or own a combined total of 105 megawatts of electricity generating capacity from renewable sources.[8]
Iowa’s Sen. Grassley sponsored the Production Tax Credit, which first passed Congress in 1992.[9] The law granted a 1.5 cents-per-kilowatt-hour federal tax credit (in 1993 dollars) to wind energy producers for 10 years after they began service. In 2015, Congress voted to phase down the credit for wind facilities (through 2019) and to eliminate the credit for other renewable power generating facilities constructed after December 31, 2016.[10][11]
Wind energy producers in Iowa may also qualify for one of two state tax credits (for either 1 cent or 1.5 cents per kilowatt-hour) over a 10-year period, depending on generation capacity and other criteria.[12][13]
In contrast to the tax credits and other wind power subsidies, federal officials have issued stricter regulations on the use of coal as a feedstock for electricity generation. For example, the Obama administration finalized its Clean Power Plan (CPP) in October 2015, establishing carbon dioxide emission reduction requirements for new and existing power plants. Under the CPP, states are required to develop plans to reduce emissions and seek approval from the Environmental Protection Agency. Plans must include a combination of the following measures: increasing energy efficiency; shifting from coal to natural gas; and generating more electricity from lower-emission sources such as nuclear power and renewable sources.
On March 28, following an executive order from President Trump, EPA Administrator Scott Pruitt announced the agency would review and, if appropriate, repeal the CPP, the provisions of which had not yet gone into law due to legal challenges.[14]Cite error: Closing </ref>

Nationwide, 5.5 percent of electricity was generated from wind in 2016.[15]

Conclusion
Secretary of Energy Rick Perry ordered a review of the impact of renewable energy policies on electric grid reliability. A Daily Caller article detailing criticisms of the review by the wind industry and others claimed that “Iowa gets nearly 40 percent of its electricity from wind turbines.”[3]
An estimated 36.6 percent of electricity in Iowa was generated using wind power in 2016.[4]
