Some recent nights have been noticeably cooler, a sure sign that fall is on the way. The colder weather outside reminds us that we will soon need to activate our home heating systems so it’s an appropriate time to think about energy conservation. The city of Lowell has launched a new program to help owners of homes (1-4 family) in ways that go beyond the well-known MassSave program. Among other things, the Lowell program provides for low interest loans of up to $20,000 for a single family home (with an additional $10,000 for the next three units) to install things like a solar photovoltaic system. An application with more information about the program is available HERE.
