Renewegy is the realization of a dream to bring decades of clean energy product development experience to the wind and high-efficiency propulsion markets. As a company we believe in making the right choices, and we want to help our customers do the same. We want to crush the notion that alternative energy isn’t economical.

Our vision is to see our clients reduce their dependence on traditional sources of energy, saving them money and building their image in the process. Our engineers and product development teams work tirelessly to create the highest quality products available in our industry.


We are dedicated to designing and building systems that are made in our own back yard, right here in America. From engineering, to production, to preventive maintenance and service, we fully support local communities and their economies. You can say we have a “domestic agenda”.
