REPP identified all the 6-digit NAICS codes that include firms involved in activities similar to the manufacturing of the individual renewable energy components found in wind, solar, biomass or geothermal production. For example, a company that makes glass plate (NAICS 327211 Flat Glass Manufacturing) could potentially transfer their capabilities to making the top surface glass for photovoltaic solar modules.
