The 2018 ACTT Summit: Powering Our Future, at Mount Desert Island High School on January 28 was an inspiration for over 280 people from MDI and the coastal region. Led by over 20 knowledgeable presenters who are taking charge of our energy future and leading climate change action, we shared success stories, confronted challenges, and left feeling hopeful!

Josh Castonguay, VP of Innovation for Green Mountain Power, Calls for transforming our century old energy grid

Josh kicked off the 2018 ACTT Summit with a compelling case for moving away from large, centralized, fossil fuel and nuclear power plants to decentralized power that places renewable energy production close to the customer. Green Mountain Power is already applying futuristic and  innovative energy solutions from solar to Tesla batteries, to electric vehicles, and smart monitoring technology that reduce energy use, carbon emissions, and costs ... while making energy delivery more safe and reliable.


Rethinking Plastics program highlights growing crisis of plastics

Madelyn Woods, Marine Research Coordinator, Marine and Environmental Research Institute discussed the results of micro-plastics sampling in Blue Hill Bay and the sources, fate, and impact of plastics on human health and the food chain to a packed audience at Southwest Harbor Library on January 9. She stressed that plastics, which never breakdown, (only get smaller) are in our air, water, food, and bodies posing very serious health threats.

Carey Donovan of the Zero Waste Committee explained why single use plastic packaging, a problem we can no longer avoid since it makes up a quarter of the 8 million tons of plastic waste that flows into our oceans each year. are a useful area of focus for local action.

Doubling Solar Capacity in 2018 and 2019 through Grid Scale Solar Photovoltaics

Our volunteer team is investigating suitable sites on MDI that can support a large solar PV array with minimal impact on the environment, the community, and scenery. Grid-scale solar will increase our energy security, reduce the export of energy dollars off-island, and support our local economy. Join us.


Click on the map above to see the locations that collectively doubled our solar energy generating capacity since this past April when we launched our Solarize MDI campaign with ReVision Energy. MDI had a total installed capacity of 646 kW of solar photovoltaics then. We now have 643 kW more! And ACTT has plans to double that again each year in 2018 and 2019.


Mini-Grants for Climate Change Service Learning Projects

Thanks to a grant from the Fisher Foundation, grants of $50-250 will be offered to support student and teacher initiated service learning projects that address climate change and sustainability issues, increase environmental literacy, and empower students to take action. Applications available here online.



Many MDI businesses are working hard to reduce fossil fuel use, add solar energy, eliminate disposable plastics, and/or use local and sustainably grown food.
