Marguerite Wells serves as the executive director of the Alliance of Clean Energy New York (ACE NY). She joined the ACE NY team in April of 2024. 

In the wake of the unprecedented federal attacks on the renewable energy industry, Marguerite worked to file the first lawsuit filed by a clean energy trade organization against the White House, challenging President Trump’s ban on new wind projects. ACE NY and 17 state attorneys general and the District of Columbia filed the suit in May 2025, with a positive ruling, throwing out President Trump’s directive in December 2025. 

Marguerite is now working in multiple national coalitions of clean energy trade associations to challenge federal targeting of renewable energy projects. 

In New York, Marguerite has worked to bridge communication and build relationships between state regulators, the renewable energy industry, environmental advocates, and agricultural interests to devise compromises that can lead to better outcomes for all. 

Marguerite has led ACE NY through a period of growth, expanding the ACE NY team to better meet the needs and demands of today. During this time, ACE NY was named one of City & State’s Top Workplaces. 

Marguerite regularly speaks as a subject matter expert at events across the country, including CCSA’s Community & Distributed Energy Summit in Washington D.C., Infocast’s New York Energy Summit in Albany, and City & State NY’s Clean Energy in New York Summit in NYC. 

Previously, Marguerite headed up Invenergy’s New York development office for seven years, where she worked on 2 GW of renewable energy projects. 

Before her time at Invenergy, Marguerite developed Black Oak Wind Farm, a 16 MW wind project in central New York where she crowdfunded $3 million in community investment to develop the project.   

Marguerite also has an entrepreneurial background. In 2005, she built and eventually sold Motherplants, a green roof plant nursery business that has supplied many of the green roofs built in NYS. 

Marguerite is a fifth-generation New Yorker, and a graduate of Cornell with a Bachelor’s in Animal Science and Natural Resources. She got her Master’s in Environmental Sustainability back before anyone had heard the word “sustainability” from the University of Edinburgh in Scotland. 

In her spare time, you can find Marguerite pursuing her passions of farming and gardening when she isn’t watching her kids play sports.
