The holy grail of getting solid state white light from light emitting diodes (LED) was elusive. To produce white light from these solid state devices, you need blue diodes. Blue LEDs didn’t exist; physics made it hard and scientists and engineers could not beat the blue diode problem. Until . . .
To reduce home energy consumption as rates rise, one town in Northwest Massachusetts has found a creative do-it-yourself solution.
“It’s a house, it’s a car, it’s a … solar panel?” In the coming months, the Department of Energy Resources (DOER) is hoping a new residential solar loan program will spark that question and interest in renewable power at local lending institutions across the Commonwealth. …Continue Reading Banking on Residential Solar Power
The American Council for Energy Efficient-Economy (ACEEE) selected me to present a paper on the Commonwealth’s Green Communities Program at ACEEE’s Summer Study on Energy Efficiency in Buildings. It felt like going to college – the seniors all knew each other, while the freshmen were …Continue Reading Building Efficiency Gurus Exchange Ideas on Just About Everything
Until recently, there was no way to easily figure energy efficiency into a home buying decision. Enter HomeMPG, a Massachusetts energy-saving initiative to pilot an energy performance score (EPS) in residential homes. This “asset” rating that’s analogous to a car’s MPG rating. Behavior is taken out of the equation so that any home’s energy use can be compared to any other home, allowing for an apples-to-apples comparison.
Massachusetts has just surpassed an exciting milestone of 15,000 solar photovoltaic (PV) installations, proving that solar energy has become a smart, popular choice here. In fact, as of August 21, there were 15,762 systems installed across Massachusetts, a twenty-fold increase from 2007 when Governor Deval …Continue Reading Massachusetts Milestone: 15,000 Solar Installations
The results of the Solarize Mass 2013-2014 two rounds managed to surpass numbers from the previous two years. Close to 1,500 contracts were signed and a total of nearly 10 megawatts of solar installed. During 2013’s first round, ten communities participated, and for the second round that ended this past June, another fifteen communities were chosen.
The five UMass university campuses have made enormous progress towards carbon neutrality. In particular, UMass Amherst has demonstrated impressive environmental leadership and received an Energy and Environmental Affairs’ Leading by Example award for achieving a 26 percent reduction in greenhouse gas emissions three years ahead of its 2012 goal.
Greenfield sent program specialists from Energy Smart Homes door-to-door to answer questions, explain the energy auditing process, and plan retrofit projects. So far, home energy assessments in Greenfield have taken place at four times the statewide rate.
This April, the Commonwealth launched its second Solar Carve- Out Program. Built on the success of the first solar carve-out program, SREC II is designed to continue to drive Massachusetts’ solar growth and particularly provide incentives for smaller solar projects, building mounted units, community shared solar, solar canopies, emergency power and low income housing.
