Greentree advisors have been analyzing and identifying regional supply chains and workforce requirements for clean energy industries since 2009, then with a focus on land-based wind and solar. We expanded our work in 2012 to the offshore wind market, conducting supply chain research and analysis for the U.S. Department of Energy, state economic develop organizations, and offshore wind. In 2015, we again expanded our supply chain analysis into PEM automotive fuel cells, assessing U.S. and global manufacturers competitiveness for hydrogen and fuel cell components. Having a ready, trained, and available regional workforce is key to the construction, installation, and ongoing operations and maintenance of any renewable energy power installation. Greentree advisors have conducted several state studies on workforce to assess developers, manufacturers, and service providers workforce needs during the entire life-cycle of a renewable energy installation, compared to the current state workforce and jobs training availability. Educating U.S. manufacturers, service providers, and state and regional economic development organizations, on the emerging clean energy industry has been a focus of our work since our beginning. Greentree advisors have conducted more than 40 supply chain workshops across the country, and multiple online webinars, for state economic development organizations, wind developers, and the U.S. Department of Energy, focused on educating potential suppliers to the opportunities in these new markets.
