The Vermont Department of Health reports strong evidence for the positive impact of home weatherization on general health, productivity, social health, and upper respiratory health. They estimate that the 10-year benefit of weatherization, in health and fuel savings, is nearly three times greater than the initial investment per household.
Further, a 2016 study from the American Lung Association found that Vermont stands to save $313 million in total health and climate costs by transitioning to a majority of electric vehicles by 2050.
