To mark Earth Day this year, the group WeatherizeDC has kicked off a public education campaign to preach the benefits of better insulation, energy efficient home appliances, and other tools of the "weatherization" trade.
William Nesbitt, a volunteer with the group, says that when he makes his pitch, he talks up the environmental benefits of a more energy efficient home.
But he says it's the promise of lower energy bills that usually seals the deal.
"I emphasize the cost savings, their eyes get big, you can pitch them on the rest later," says Nesbit.
WeatherizeDC has set up a series of home meetings across the city, which volunteers going door-to-door will encourage residents to attend.
"It's sort of a positive peer pressure," says Nesbit. "When somebody comes knocks on your door and says, 'hey come do this,' you're like, 'what do you want?' But if its homeowners like yourself, you're more receptive to your neighbors."
A group spokeswoman says she hopes the effort will create about ten full-time jobs for District residents trained in weatherization.
