AllEarth Renewables has over 25 years of experience designing and manufacturing wind and solar renewable energy systems. It began with the pioneering vision of its founder, David Blittersdorf.David grew up in Pittsford, Vermont within view of Grandpa’s Knob, the site of the world’s first large-scale wind turbine, which inspired his early fascination with creating clean energy from the wind. During his teenage years, David began tinkering with model wind turbines for fun. His hobby became a passion in 1973 during the Arab Oil Embargo. With his first driver’s license in hand and gasoline in short supply, the effects of our nation’s oil addiction became painfully clear. So, for his senior year engineering project at the University of Vermont, David built his first working wind turbine.In 1982, when the wind energy industry was in its infancy, David founded NRG Systems, a pioneering manufacturer of wind measurement systems.

AllEarth Renewables is dedicated to the design and manufacture of innovative technologies that provide renewable energy solutions for homeowners and businesses while creating sustainable, well-paying jobs.

Our grid-connected solar electric systems enable individuals to decrease their dependence on nuclear and fossil fuels, reduce greenhouse gas emissions, and embark on the road to a more secure energy future.



We envision a day when solar trackers and home wind turbines will be as commonplace as the two-car garage and the microwave oven.

We visualize a landscape dotted with wind turbines and solar panels powering homes, farms and small businesses.

We strive to create products that bring us closer to when our nation can break from its reliance on foreign oil, nuclear power and other polluting energy sources that are compromising our health, our air quality, our pristine waters and mountain vistas.

We embrace the opportunity to use small scale renewable energy to promote a secure energy future for homeowners, businesses, our children and grandchildren.

Every AllEarth Solar Tracker is designed, tested, and engineered in Vermont.

We’re passionate about what we do and where we are. Far from being an overnight success, we’ve earned national recognition by taking our thirty years of experience in the renewable energy industry and constantly innovating our products, our thinking, and our goals.

David Blittersdorf, our CEO, isn’t new to renewable energy. When he was 14 he built his first wind turbine to light the small shack where he boiled sap into maple syrup. As a student at the University of Vermont, he built yet another wind turbine. And after he graduated, he went on to found and lead Renewable NRG Systems—one of the most successful wind-energy companies in the U.S. On New Year’s Eve 2008, he sketched out the initial design for a solar tracker that followed the sun like a sunflower. And AllEarth Renewables was born.

Following his example, we believe that having experience doesn’t mean you can’t always be looking for new answers. We’ve built two 25-acre, 382 tracker, 2.1 MW solar farms in our own backyard so that we can fine-tune every aspect of our product, services, and delivery for our customers.
