Evidence of that influence can be seen at the Statehouse. A bill by the Senate president pro tem to ban any new wind farms in the eastern half of the state was quickly scuttled in the House. When state Rep. Earl Sears tried to amend the proposal to include some basic regulations for the industry, lobbyists killed that idea, too.
"I personally believe that wind power has a place in Oklahoma, but I'm frustrated," Sears said. "I think they should have more regulations."

Wind developers say they're just protecting their investment — more than $6 billion spent on construction of wind farms in Oklahoma over a decade, according to a study commissioned by the industry. In addition to royalties paid to landowners, the giant turbines themselves are valued at as much as $3 million each.

Monte Tucker, a farmer and rancher from Sweetwater in far western Oklahoma, said his family has received annual payments of more than $30,000 for the four wind turbines placed on their ranch two years ago.
"We're generating money out of thin air," Tucker said. "And if the landowners don't want them, the developers have to go somewhere else."
Tucker says the turbines take only about 5 acres of his property out of production, and they have not affected the deer, turkey and quail hunting on the land. On a recent 101-degree day, he found about 40 of his cows lined up in a single row in the turbine's shadow.
Meanwhile, a formal inquiry into how the industry operates in Oklahoma is being launched by a state regulatory agency at lawmakers' request. The fact-finding mission could lead to legislation targeting the industry.

The turbines are subject to local property taxes after a five-year exemption for which the state reimburses local counties and schools. The exemption for wind producers was designed to offset a lifetime property tax exemption in neighboring Kansas.
In addition, the state offers wind developers tax credits based on per-kilowatt production that can be applied to any corporate income tax liability and then sold back to the state for 85 cents on the dollar. Those cash subsidies are expected to total $80 million over the next four years, according to estimates from the Oklahoma Tax Commission.
Oklahoma is one of at least six states competing for wind industry development, which often breathes life into communities that have lost manufacturing jobs and family farms.
Over the last decade, the number of wind-generated megawatts has grown from 6,000 in 2003 to 61,000 last year, which equates to roughly 30,000 turbines.
The biggest wind industry boom is taking place in Texas. Iowa and Oklahoma are close behind. Other states that have announced major projects include Kansas, North Dakota and New Mexico, according to the American Wind Energy Association, a trade group.

In Kansas, Republican Gov. Sam Brownback is trying to balance his state's embrace of wind with opposition to a 2009 state energy law that requires utilities to use more wind and other renewable sources of power. Brownback supports wind energy, but his political base includes free-market GOP conservatives who oppose such mandates.
Texas Comptroller Susan Combs released a report last week urging an end to state subsidies for wind power, saying that tax credits and property tax limits helped grow the industry but today give it an unfair advantage.
"It's time," Combs said, "for wind to stand on its own two feet."
