Weatherization Stimulus: Lots of It, Fast - BusinessWeek: "According to the DOE Weatherization Program, $1 invested returns $1.65 in energy-related benefits, and at the same time leverages $1.54 in other resources from private funding, utilities, state funds, and other federal funds. A home that's weatherized at a cost of several thousand dollars can save some $350 per year on energy bills, claims the Obama Administration. (The Weatherization Program's estimate comes in at about $413.)
For low-income families, such savings could be crucial. According to an Oak Ridge National Laboratory study, low-income families paid 17% of their annual income on energy, compared with the 4% spent by higher-income households."
