The following information was released by the New Hampshire Community Development Finance Authority (CDFA): A group of homeowners gathered at Tea Birds Restaurant Tuesday night to celebrate the end of their addiction to home heating oil. "Every time the oil truck goes by, I smile," said Marie Canning. Canning's home is one of 36 Berlin homes that has or is in the process of replacing its oil burner with a high efficiency wood pellet boiler. It is estimated the 36 homeowners combined will save more than $50,000 a year in heating costs. In addition to saving money, the homeowners are also proving that switching to a local renewable energy source helps the local economy and the environment. The project is expected to have a $200,000 annual impact on the local economy.
