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.
For the past two years, Massachusetts has participated in a federal program that recognizes schools working hard to educate future generations about clean energy and improvements in Massachusetts school buildings. This year, the Commonwealth will again participate in the U.S. Department of Education’s Green Ribbon Schools recognition program.
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.
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.
Energy measures implemented at a Mass. Military Divison site include improved lighting, high efficiency motors, HVAC controls and energy management system upgrades. Under the Accelerate Efficiency Plan, the Commonwealth is investing over $12 million at 29 state facilities throughout the Berkshires.
Electricity usage throughout New England reaches its peak during summer heat waves, causing our electricity bills to spike. During periods of high demand, electric utilities typically call on more expensive “peaking” plants to provide extra power. These costs are passed onto larger, non-residential consumers through demand charges on their monthly electricity bill. Municipal buildings can save a significant sum of money if they shut off portions of their electricity during these peak periods.
The MOR-EV initiative provides rebates of up to $2,500 for electric, fuel cell vehicles and plug-in vehicles with large batteries, and $1,500 for plug-in electric vehicles with smaller batteries. All Massachusetts residents are eligible to receive incentives on purchased and leased new electric vehicles until the rebate funds are gone.
