Did you know that: Energy use for lighting in the new High Rock School is 35% less than code thanks to high efficiency lighting and extensive use of natural light? School buildings designed to a higher standard of energy and
Green Kids groups are active at each of Needham’s Elementary Schools. These student groups, guided by volunteer teachers and parents, organize and run energy and environment-themed educational and service programs at their schools and in the community.

Black Friday means shopping for some, but Green Monday is savings for everyone. Join us on the Monday after Thanksgiving – November 26th at 7:00 pm at the Library Community Room for “Better by Design – energy efficiency in Needham’s
The Selectmen will appoint the members of the Solar Exploratory Committee at their November 14th meeting. The Committee, authorized by the Selectmen at their September 11th meeting, generated strong interest from Needham citizens interested in serving. The seven residents selected
Most solar panels have an expected lifetime of 25 years, with very little maintenance required. The individual components have lifetimes of ten years and up. The cost of maintenance and extended warranties will be an important factor of the project’s
Because photovoltaic (PV) solar systems use the full spectrum of light, the ultraviolet rays are still charging the system, even when the sunlight isn’t visible. Obviously, the system will produce more power on bright sunny days. In the event of
Solar systems that produce electricity are known as photovoltaic, or PV, systems. The term “photovoltaics” refers to the direct conversion of light into electricity at the atomic level, using silicon semiconductor materials. The power produced in direct current, or DC.
Any project built at the RTS has to be done in conjunction with the State Department of Environmental Protection (DEP), who is responsible for insuring that closed and capped landfills do not pose an environmental threat. The system can be
The PV panels, mounted in frames (arrays), would go on top of the capped former landfill. (This is the flat-topped “hill” that you see, behind the transfer station area.) The transfer station, yard waste and composting areas won’t be affected.
