Most of the average home's air leakage is due to the stack effect. This cycle - in which warm, buoyant air rises up out of the attic and cold replacement air is pulled in through the foundation - leads to cold floors, uneven temperatures, and compromised indoor air quality.
It’s not your imagination: Maine really did just go through the warmest winter in 121 years of record keeping, and we had lots of company. According to NOAA data released this week, almost every state experienced warmer-than-normal temperatures, all six New England states set winter records, and spring has already sprung.

Conventional wisdom tells us that windows and doors are responsible for most air loss in a house, but conventional wisdom isn’t always wise.
Once again, we're teaming up with ReVision Energy and the Natural Resources Council of Maine for a women's evening of questions and conversation about heating systems, fuel choices, energy efficiency, solar power, state energy policy, and more.
The Supreme Court has rightly been on everyone's mind since the death of Justice Antonin Scalia on Saturday. The clean energy world was already focused on the high court, which temporarily blocked implementation of the Clean Power Plan last week, and it's wondering what the sudden vacancy means for the landmark regulation.

Homeowners can claim federal tax credits for energy efficiency improvements made in 2015 and 2016, thanks to an extension of the Residential Energy Tax Credit. The credit covers 10% of the materials cost of certain improvements, up to $500. The credit had previously expired at the end of 2014, but a late-December budget deal extended it both retroactively and forward till the end of 2016.

When Brunswick Junior High teacher Cris Lavigne told us about the weatherization project her 7th graders are working on, we knew we wanted in. How could we say no to an interdisciplinary project that highlights the science, economics, politics, and logistics of energy efficiency?
We always enjoy Efficiency Maine's annual symposium, and this year's event was no exception. We caught up with colleagues; helped honor our friend Rick Karg for his incredible contributions to the field of building science; and listened to U.S. Senator Susan Collins speak eloquently about the need for - and benefits of - urgent action on climate change.
In honor of their 10th anniversary, the SunriseGuide is celebrating Mainers who create real change in their communities. The 2016 Stewards of Sustainability have helped make "significant advances in the areas of sustainability, environmental health, and wellness," and Evergreen founder and CEO Richard Burbank is among them!

Yesterday, Efficiency Maine’s board voted unanimously to adopt a new 3-year plan and budget, which will save consumers more than $870 million on energy bills over the lifetime of the efficiency measures. The plan now goes to the Public Utilities Commission for a formal review, expected to take at least four months, before it can be implemented.
