The most experienced NABCEP
certified professional in the region



Ian established Greene Tech Renewable Energy in 2008. Long before that, he graduated from the New England Culinary Institute and embarked on a distinguished career as a professional Chef, culminating in his role as the Executive Chef at the World Golf Village Hall of Fame Renaissance in St. Augustine, FL. Despite his success in culinary arts, Ian dedicated his spare time to researching and immersing himself in the field of renewable energy. Eventually, he relocated his family to Tennessee and transitioned back to his original profession in electrical work, specializing in renewable energy solutions for individuals and businesses.  

For over 16 years, Ian and his team have installed, repaired, and upgraded renewable energy systems across the northeast Tennessee region. No solar, hydro, or wind professional in the region has more experience than Ian Huddleston and the GTRE team.
