Description On a quick scan of Alerion's name, you might be forgiven for thinking the company makes ailerons. But, no, Alerion is not in the aircraft parts business -- it's an investment firm focusing primarily on the renewable energy sector. The company operates with stakes in such companies as Alerion Energie Rinnovable (renewable energy), Reno De Medici (a recycled cardboard producer), RdM Realty (real estate), and Mediapason (media). Alerion also invests in companies in the banking and financial services industries. Formed in 1995 as IBI, the company was publicly traded in 2003 and changed its name to Alerion.
