Vermont cities and towns are being urged to enter the Home Energy Challenge.
Gov. Peter Shumlin says the competition could save Vermonters $2.6 million on heating bills over the next year.
About half of the state's communities are signed up for the Home Energy Challenge.
Residents, like Montpelier homeowner Rob Apple, are encouraged to weatherize and cash in on savings and state rebates.
"Debated it internally for several years, in terms of the cost and the dollars and the payback, and finally one day said 'this is crazy, I can't keep paying what I'm paying for oil. This house needs to be tightened up," Apple said.
Apple says he spent about $8,000 to seal up his old house. He says his heating bill has dropped about 20 percent, and he expects to make up his investment over the course of the next few years.
