Hoping to drum up support for the Homestar energy-efficiency program, President Barack Obama spoke today at Savannah Technical College in Georgia about the $6 billion cash for caulkers program, or Homestar.

Under the Homestar plan, you'd get a 50 percent rebate up to $3,000 on insulation, duct sealing, windows, roofing, and heating and cooling equipment, and other energy-efficiency improvements. If you pay for a full energy audit and follow through on its recommendations to boost the overall energy efficiency of your home by at least 20 percent, you'd receive a $3,000 rebate.

Administration officials expect 2 million to 3 million homeowners to participate in the cash for caulkers program, which must approved by Congress.

Cash for caulkers is another example of the administration's energy-efficiency efforts, joining the $300 million cash for clunkers for appliances and the $4.7 billion Weatherization Assistance Program. It's also part of the administration's effort to create new jobs.

"Here's one of the best things about energy efficiency. It turns out that energy-efficient windows or insulation, those things are products that are almost exclusively manufactured right here in the United States of America. It's very hard to ship windows from China. So a lot of these materials are made right here in America," said the president.
