The government is pumping .7 billion in stimulus money into a relatively unknown program that weatherizes homes, installing insulation and making them more energy efficient. But some are concerned that the money — enough to weatherize more than seven times the average number of homes per year — could be wasted.

Montgomery, Ala. ? Ready or not, states are getting a tenfold boost in federal money to weatherize drafty homes, an increase so huge it has raised fears of waste and fraud and set off a scramble to find workers and houses for them to repair.

An obscure program that installs insulation in homes and makes them more energy-efficient is distributing $4.7 billion in stimulus funds — dwarfing the $447 million originally planned by Congress this year and the $227 million spent in 2008.

That is enough to weatherize 1 million homes, instead of the 140,000 normally done each year.

President Barack Obama said pouring money into the program would lower utility bills for cash-strapped families, provide jobs for construction workers idled by the housing slump, and make the nation more energy-efficient.

“You’re getting a three-fer,” Obama said. “That’s exactly the kind of program we should be funding.”

But some worry states won’t be able to keep track of the money.

Leslie Paige, spokeswoman for the Council for Citizens Against Government Waste, said the program was open to fraud because of the way oversight was divided. The federal government passes the money to states, which pass it to community action agencies, and the agencies pass it to contractors who work with customers.

“It’s such a Rube Goldberg operation it should be setting off alarm bells,” she said.

Energy Department spokeswoman Christina Kielich defended the program, saying the federal government monitors state operations and does a thorough review at least every two years of the local organizations. In addition, states are getting their money in increments and must demonstrate quality control to get more.

The program helps low-income families take steps to reduce their home energy expenses, from caulking leaky windows to replacing heating and cooling systems. The Energy Department says 6.2 million households have benefited since it began in 1976, saving the average household about $350 a year on energy bills.

The funding for New York is going up from $20.1 million last year to $395 million. California’s share is soaring from $6.3 million to $185.8 million. Virginia’s is going up 23 1/2 times, from $4 million annually to $94.1 million.

“I was stunned,” said Shea Hollifield, Virginia’s deputy director of housing. “Spending that much money will be a challenge.”

States are hurrying to find qualified weatherization workers and caulk-ready homes.

Alabama plans to train home builders in how to bid for weatherization contracts. Russell Davis, vice president of the Alabama Home Builders Association, said builders who once had no interest in weatherization contracts now see them as a way to keep their crews busy.

In many states, qualified homeowners are already on waiting lists. But some states don’t have enough recipients.

“We are out of clients. We need clients bad,” said Cade Gunnells, weatherization coordinator for three counties in central Alabama.

To help find them, states are updating Web sites about the expanded program and working with nonprofit groups, churches and the news media to get the word out.

Charles Uptain, a 73-year-old retiree, had his Montgomery home repaired in the weatherized program last year. His utility bills went down by about $60 a month after workers fixed leaky windows, replaced cracked panes, re-taped air-conditioning ducts and blew in new insulation. Uptain’s house required slightly more than $3,000.

“This wasn’t wasteful spending. This was well-spent money,” Uptain said.
