The Weatherization Assistance Program in Alameda County aims to reduce energy costs for income-eligible households by improving home energy efficiency while ensuring health and safety, particularly for vulnerable groups. The program, funded by federal and state agencies, is available across most of Alameda County until March 2012 or until funds are exhausted, offering benefits such as reduced energy bills and improved indoor air quality. Eligibility requires households to have a total gross income at or below 75% of California's state median income, along with submission of necessary documentation for participation.
