With about 200 vendors, the nearly 15,000 homeowners expected to show up this weekend, have a lot of options when it comes to sprucing up their homes.

"We are just here looking around to see if something jumps out at us that we might want to do to the yard or do to the house, we're doing some work upstairs," says Rockford resident Laurel McVinnie.

This year's theme seems to be eco-friendly, to help save the environment and our wallets.

Cindy Pope, Sales and Marketing Manager with American Water Treatment Inc. says, "Purifying your water at home is much less expensive than buying water at the store and you get much better quality and of course now that there's no waste water it's much more environmentally friendly."

Cutting down on water expenses is just the beginning. With green insulation, homeowners can also save their electric bill.

"Heat and cold can't transfer through this glass, that's where most of the energy is lost through a home with our windows, customers tell us that usually it cuts their energy bill in half, says owner of Advanced Window System, Dennis Schindler.

Vendors at ISP are showing off their latest eco-friendly products, giving homeowners a window of opportunity to go green.

"We would do the eco to save energy, even if it's a little expensive to start with, in the long-run it would work out," says Laurel McVinnie.

Other homeowners agree, saying green energy is inevitable.

James Case says, "It's the future, we can't go on the way we are."

For more tips on eco-friendly, cost-saving home improvements, the Rockford Home Show runs all weekend. The event is being held from 10 a.m. - 7 p.m. Saturday and from 11 a.m. - 5 p.m. on Sunday at the Indoor Sports Center in Loves Park.
