Wind power has started to become a popular way for homeowners to generate their own energy, but some new rules in Nashville could limit how green homeowners can get.

One resident in the city is already using a wind tower on his property to pump power into his home.

As more people decide to go green by using wind power, Metro councilman Charlie Tygard said he doesn't want some people's efforts to save money to alter other people's quality of living.

Tygard is sponsoring a bill that would put restrictions on wind towers that produce energy.

He said he wants the public to remember when cell phone towers started popping up and how it caused residential complaints. The councilman said the city needs to make sure that doesn't happen with the wind machines.

"What are the height, aesthetic, noise regulations? What if somebody quits using them? Does it have to be taken down," said Tygard.

The machines are not cheap and can cost as much as $15,000 to $20,000, but Tygard said it's an investment many people may be willing to make since wind energy can cut residential power bills by 80 percent.

Tygard said he is looking at building one of the machines outside his home. His proposal would limit its size and cap a system's capacity to 50 kilowatts or less based on the location of the tower.

So far, few people have complained about the wind machines, but west Nashville resident Mike Conatta said before they creep up into his area, he'd like to see them regulated.

"There's kids that live around here. They might be climbing on it. You never know what could happen, if they break down, pieces may fly off it," said Canatta.

The Metro Council will take up the proposal at its next meeting.
