Save on your energy bills, save the climate, and be more comfortable in your home: The JP Forum presents a weatherization workshop this Friday at First Church. The forum, led by representatives from the Boston Building Materials Co-op and the Boston Climate Action Network, will start with the basics of how heat gets lost in your home. Then the talk will explore ways to reduce the energy that gets used intentionally and unintentionally. There will be a discussion of "no brainer" steps you can take (easy ways of increasing efficiency and reducing demand) to more challenging long term measures.Action Network. The event is sponsored by JP Greenhouse, Boston Climate Action Network, Cool JP, and Bikes not Bombs.
