Local governments are beginning to flex their permitting authority to challenge commercial-scale wind farms, a trend some industry observers say could impede broader federal efforts to expand renewable energy production. The latest round in the emerging battle between local governments and wind-energy developers occurred last week in Kansas, where the state Supreme Court upheld a Wabaunsee County zoning ordinance banning industrial-scale wind ...Experts say the Wabaunsee ordinance, unanimously upheld by the Kansas court, is a key test of local governments' power to effectively ban large-scale wind farms, as opposed to blocking a specific project or proposal.

The Kansas Supreme Court ruled Friday that Wabaunsee County commissioners have the right to prohibit the construction of commercial wind farms in their county. But the court also questioned whether an ordinance banning commercial farms but allowing smaller wind generators for personal use violated some provisions of the U.S. Constitution. Commissioners adopted the ordinance in 2004. In a unanimous decision, the court acknowledged the commission's concerns about potential harm to the aesthetics and ecology of the Flint Hills if huge wind turbines were erected in Wabaunsee County.

In a case pitting the beauty of the Flint Hills against large wind farms, the Flint Hills won. The Kansas Supreme Court ruled Friday in favor of a zoning ordinance in Wabaunsee County that prohibits commercial wind farms. Poised as the third best state in the country for wind power and on the cusp of a renewable energy revolution, Kansas has the potential to be at the epicenter of the wind industry.

While it appeared briefly Monday that the lights were out on a proposed high-voltage electric transmission line that would serve the state's growing wind industry, officials recharged the plan Tuesday. The Southwest Power Pool Inc.'s board of directors on Tuesday included the $518 million "Spearville line" in a package of transmission expansion projects it was forwarding for further study and probable approval. The 765-kilovolt line would go from Spearville, the site of a wind farm in southwest Kansas, to Wichita and down to the Oklahoma border, where it could hook into lines to other states.

After months of information gathering, Ellis County commissioners revisited proposed changes to the county's zoning regulations during Monday's meeting. However, they still took no action on the changes. Specifically, commissioners discussed proposed changes to setback requirements and noise standards in the regulations. Commissioner Glenn Diehl said he wants to protect platted, multiple-lot developments in the county the most. He proposed a 1.5-mile setback for wind turbine location from those areas.

A project to put up a wind turbine at Hope Street Academy generated a civics lesson for students there, five of whom asked the city's governing body Tuesday evening to allow small wind energy systems to operate in Topeka for nonresidential purposes. The governing body, which includes the city council and Mayor Bill Bunten, subsequently voted 10-0 to approve an ordinance making that move and a companion measure requiring users of wind energy systems to acquire a conditional-use permit from the governing body.

The preserve itself has grown to 39,100 acres. But that's only a fraction of the 3.8-million-acre region known as the Flint Hills, straddling the Oklahoma-Kansas state line with the largest remaining patch of tallgrass prairie on the continent. ...While wind power generates clean energy, the vast networks of turbines, roads and power grids can disturb a natural ecosystem just as much as any other industrialization, Hamilton says.
