Renewable energy development creates jobs primarily in sales, finance, operations and engineering, the latter being also critical for design and implementation. Medium and lower skilled workers are needed for the installation and maintenance of renewable energy technologies. The training of engineers is most effective if administered in connection with actors operating in the renewable energy sector, such as at the Energy Resources Center at the University of Illinois at Chicago (Schrock, 2009). In regards to wind turbine manufacturing, the existing efforts to inform and retool local manufacturers should also include skill upgrades of the manufacturing workforce as necessary for working for original equipment manufacturers of wind turbines. To this effect, the work done by the Chicago Manufacturing Center, Jane Addams Resource Corporation and the Chicago Manufacturing Renaissance Council is leading the way, but could improve if complemented with a stronger workforce training component (Schrock, 2009). At the development level, projects can involve those trained in electrical and mechanical engineering and computer science.
