Home + Energy Chats: Reducing home heating costs—now and in the future

Home + Energy Chats is a webinar series that brings together green building industry experts and those interested in learning more about healthy, efficient and sustainable homes.

As we head into heating season, what home improvements can make the biggest difference in your energy bills? We’re bringing back home performance expert Colin McCullough to explore which upgrades can deliver the greatest savings now and over the long term—and how to decide where to start. Using real-life Maine homes, we'll look at where different levels of investment can have the greatest impact. We’ll also explore how to weigh upfront costs against potential energy savings, comfort and long-term value, so you can make informed decisions about which improvements make the most sense for your home and budget.

Sustainable Neighborhoods with Troy Moon

Sustainable Neighborhoods with Troy Moon

Join Troy Moon, Sustainability Director for the City of Portland, as he discusses the Sustainable Neighborhoods Program.

To adapt to a changing climate, the most meaningful solutions often begin in your neighborhood. Studies show that communities that are more socially connected are better prepared to face emergencies and extreme weather events. A resilient neighborhood welcomes people to check in with each other, providing neighbors to call, share resources, and offer help during a crisis. The Sustainable Neighborhoods Program supports opportunities for neighbors to connect and team up to strengthen our communities’ climate resilience and take action for climate change together. Topics that will be discussed include how to apply for a neighborhood microgrant, how to host a block party or a neighborhood clean-up, how to engage with city projects that promote sustainability.

Portland’s Sustainability Series is co-hosted by the Portland Public Library and Momentum Conservation, and is sponsored by Bangor Savings Bank. The Portland Sustainability Series presents speakers who share aspects of the work needed to make Maine and our environment more sustainable. Please join us as we engage in these important topics and conversations!

DIY Thermal Shades Repair Cafe with Center for an Ecology Based Economy

  • Center for Ecology Based Economy (map)
  • Google Calendar ICS

Time to make our homes cozier and more energy efficient for the cold winter months ahead! If you are looking for a DIY alternative to WindowDressers window inserts (either to reduce plastic use or because you have cats that are likely to find irresistible joy sinking their teeth and claws into plastic window coverings), this event is for you!

CEBE’s own Roberta Hill will lead a short demonstration, covering measuring, constructing, and installing your shades. We will distribute step-by-step plans and information for where to order materials (including thermal lining fabric, rings, and cord). We may have some materials available to purchase, and can provide basic hand- and machine-sewing instruction. If you get stuck at any point, just come back to a Repair Cafe for help!

A typical house loses 25-30% of its heating and cooling through windows. Insulated lining will help keep in up to 80% of heat normally lost, and block up to 79% of the unwanted solar heat gain through windows in the summer. 

Please register ahead - space is limited. Snacks provided - feel free to bring your own food!

Home + Energy Chats: Ventilation and indoor air quality: what homeowners should know

Home + Energy Chats is a webinar series that brings together green building industry experts and those interested in learning more about healthy, efficient and sustainable homes.

We spend much of our time indoors, but how often do we think about the air we're breathing at home? Everyday activities like cooking and showering can add moisture and pollutants to indoor air, while air sealing and other energy-efficiency improvements can change how fresh air moves through a house. Join us for a practical introduction to home ventilation and indoor air quality. We’ll explore how to recognize potential ventilation problems, the roles of kitchen and bath exhaust, whole-house ventilation and air filtration, and when systems such as HRVs and ERVs may make sense. We’ll also look at ventilation strategies for both older and newer Maine homes, what homeowners should know when considering an upgrade, and simple steps you can take to create healthier indoor air.

Summer Sizzle Sustainability Series: Chemical Pollution Balance Sheet Risk

Summer Sizzle Sustainability Series: Chemical Pollution Balance Sheet Risk

How to Navigate The Unpriced Risk: Chemical Pollution as a balance sheet risk

Thursday, August 27, 12-1pm

The costs of chemical pollution are staggering. Pollution is a primary driver of biodiversity loss and over 3,600 synthetic chemicals have been found in human bodies, many linked to various health issues and costs. But chemical pollution isn't just an environmental and human health issue. It's a balance sheet risk. Bayer has $11B+ in RoundUp cancer lawsuits. 3M has $12.5B set aside for PFAS settlements and in Europe, PFAS cleanup could top €1 trillion. These aren't future risks. They're realities that business leaders and investors can no longer leave unmanaged and unpriced. ClimateWork Maine is pleased to partner with the Investor Environmental Health Network (IEHN) at Clean Production Action to learn more about these issues and how companies can navigate them by building chemical risk into their business operations and stewardship.

Speaker: Alexandra McPherson is Director of the Investor Environmental Health Network (IEHN) at Clean Production Action — an environmental solutions-based nonprofit she co-founded — where she mobilizes institutional investors to drive corporate accountability on chemical risk management and safer chemistry innovation. She brings deep expertise in communications and partnership development to multistakeholder initiatives spanning finance, industry, government, and environmental advocacy — including active engagement with the United Nations' Global Framework on Chemicals. Alexandra has forged academic partnerships resulting in the Collaborative for the Regenerative Economy (CoRE) at the University at Buffalo and Transition Finance for Sustainable Chemicals and Materials at UMass Lowell. She serves on UNH's Sustainability Advisory Board, and Change Chemistry's Member Advisory Committee. Outside work, she explores the wilderness on foot or on horse, tends her family's farm in Western New York, and cooks for anyone who will show up.

Summer Sizzle Sustainability Series: How to Talk about Climate Action & Sustainability in a Divided World: From Green Hushing to Green Shouting?

How to Talk about Climate Action & Sustainability in a Divided World: From Green Hushing to Green Shouting?

Wednesday, August 19, 12-1pm

Research shows that customers, especially Gen Z, care deeply about climate action, and that businesses are still acting, investing, and innovating on sustainability. At the same time more and more companies are choosing silence, paralyzed by fear of backlash, legal scrutiny, or saying the wrong thing at the wrong moment. How do we move from so-called “greenhushing” and how can your business continue to speak up on climate action and sustainability, responsibly? Hear from communication experts on why silence can be a strategic risk, how to maintain your brand’s visibility and communicate your company’s sustainability initiatives accurately without overclaiming.

Speaker: Jenna Klein Jonsson is the Principal and Managing Director of Blaze Partners, a 100% employee owned and B Corp Certified advertising agency based in Falmouth, Maine. Prior to co-founding Blaze, Jenna spent 15 years at L.L.Bean where she held a variety of executive-level roles including Director of Communications Strategy and Creative Director and Managing Editor. She began her career at Ski and Skiing Magazine in Boulder Colorado. In her spare time, you will find her skiing and biking with her family in Maine.
