Unlike Wisconsin, Iowa welcomes companies in the wind energy industry, according to this article by Dan Piller in the the Des Moises (Iowa) Register:
State grants West Branch wind facility $3 million
The Iowa Power Fund on Thursday awarded Acciona Wind Energy a $3 million grant to help finance a $19.9 million demonstration project near Mechanicsville that will show off Acciona’s new three-megawatt wind energy system.
“One tower will be steel and the other concrete. We’ve had requests for both,” said Joe Baker, president of Acciona’s plant at West Branch.
The four-year-old West Branch operation makes the nacelles, or the box behind the blade that houses the gears and generation capacity.
Acciona has focused on building 1.5-megawatt wind systems, but the larger units are becoming more standard in the industry, Baker said.
MidAmerican Energy’s wind farms in west-central Iowa have three-megawatt turbines.
“Within seven to 10 years most of the wind turbines will be three megawatts,” he said. A megawatt of electricity can power 200 to 500 standard-sized homes.
Iowa has 3,675 megawatts of wind generation capacity, ranking second behind Texas in total capacity and first as a percentage of its total electricity generation capacity
Acciona is a century-old Spanish company with roots in construction and water treatment. The West Branch facility, opened in 2007, is its only U.S. wind equipment factory, but Acciona operates five wind farms in Illinois, South Dakota, Oklahoma, Nevada and California.

From a commentary by Mark Z. Jacobson in the New York Daily News:
The powerful earthquake and tsunami that caused reactors at Japan’s Fukushima nuclear power plant to shut down – releasing radiation and endangering workers and evacuees – have many Americans asking whether nuclear energy is worth the investment and risk.
I say not. In fact, it should not have taken a disaster of this kind to move us decisively away from nuclear and toward safe, clean, renewable energy. . . .
If the world’s energy needs were converted to electricity for all purposes – and nuclear supplied such energy – 15,800 large nuclear reactors, one installed every day for the next 43 years, would be needed. The installation of even 5% of these would nearly double the current number of reactors, giving many more countries the potential to develop weapons. If only one weapon were used in a city, it could kill 1 to 16 million people.
***
Why do we need nuclear energy when we have safer, cleaner options that can provide greater power for a much longer period and at lower cost to society? These better options are called WWS, for “wind, water and sunlight.” The chance of catastrophe caused by nature or terrorists acting on wind or solar, in particular, is zero.
During their lifetimes, WWS technologies emit no pollution – whereas nuclear does, since continuous energy is needed to mine, transport and refine uranium and reactors require much longer to permit and install than do WWS technologies. Overall, nuclear emits 9 to 25 times more air pollution and carbon dioxide than does wind per unit energy generated.
***
Some argue that nuclear is more reliable than WWS systems. This is not true. A nuclear reactor affects a larger fraction of the grid when it fails than does a wind turbine. The average maintenance downtime of modern wind turbines on land is 2%. That of France’s 59 reactors is 21.5%, with about half due to scheduled maintenance.

While Wisconsin officials drive wind energy development out of the Badger state, next-door Iowa leads, according to anarticle by Dan Piller in the Des Moines Register:
About 15 percent of Iowa’s electricity generation capacity now comes from wind, maintaining the state’s national leadership in figures released Thursday by the American Wind Energy Association.
With a major expansion by MidAmerican Energy, Iowa stands to rise to 20 percent this year.
“That’s a percentage close to what we see in Europe, and it’s exciting,” said Jessica Isaacs, senior analyst with the wind association.
Iowa still ranks second nationally in wind capacity with 3,675 megawatts, behind Texas’ 10,085 megawatts but still ahead of California’s 3,177.
Because of Texas’ larger electricity grid, Iowa’s 15 percent of total capacity coming from wind exceeds Texas’ 7.8 percent percentage of wind to total electricity.
Iowa’s total will grow this year with the addition of 593 megawatts by MidAmerican in Calhoun, Cass, Adams, Adair and Marshall counties.
The expansions will bring Des Moines-based MidAmerican to 2,316 megawatts of capacity, the largest utility-owned and operated wind generation portfolio among investor-owned utilities.

The farm community around Rosiere, Wisconsin, Kewaunee County, came together more than ten years ago to support a wind energy development, and they’re still thankful for the wind turbines.

From an editorial in the Milwaukee Journal Sentinel:
Wind farms in Wisconsin can lessen the state’s reliance on coal-fired power plants at the same time that they add jobs to the economy. But instead of moving forward on this economic development tool, Gov. Scott Walker’s administration is taking a step back. That’s a mistake and something Walker should rethink.
What the governor and the Legislature have done is change the rules under which wind farms are sited, seeking to put greater distance between homes and wind farms. As a result, at least two firms have announced they are canceling or suspending plans to build wind farms in Wisconsin – and that means a loss of potential jobs.
Here’s what happened: Two years ago, the Legislature called on the state Public Service Commission to establish a uniform standard for wind projects across the state. The idea was that a statewide standard was better than the patchwork of local rules and moratoriums that were in place. It was a good idea, and the PSC came up with a rule.
One of its elements was a 1,250-foot setback from a neighbor’s property line; it also would have provided decibel and shadow flicker requirements for wind farm turbines.
The setback wasn’t enough for Walker and wind farm opponents; in January, the governor introduced a bill with a 1,800-foot setback, although he said this week that his administration remains open to wind energy. Last week, a legislative committee sent the PSC’s new rule back to the PSC for more work. The concern is that wind farms will hurt property values of neighboring residents.
That’s resulted in enough uncertainty over the future of wind farms in Wisconsin that Invenergy of Chicago canceled plans to develop a wind farm near Green Bay and Midwest Wind Energy suspended development of two wind farms.
A statewide standard still needs to be set by the PSC. And the legitimate concerns of neighbors of wind farms need to be taken into account without giving too much credence to fears that are unfounded and overstated. But the standard should not be so restrictive that wind farms become impractical in Wisconsin. That takes Wisconsin out of the clean energy economy – a bad bet.
