Clean Wind Energy
to Power a Stronger America
Our mission is to ensure American communities are equipped to meet the challenges of the 21st century by creating economic opportunity through clean and dependable wind energy.
If Maine can find a niche in offshore wind, it will create an industry in which Mainers will be able to work for a generation, because projects will need to be maintained and repowered over the years.
