More U.S. college students are enrolling in power- and energy-engineering courses, but the increase is not enough to meet the need, says a new report by the IEEE, the professional association of electrical engineers. About 45% of engineers at electric utilities are expected to retire or leave their jobs within five years, creating as many as 21,000 job openings, the IEEE said in the report, released in April. Lehigh University is among many universities trying to respond with course offerings. Working with the Electric Power Research Institute, the industry trade association, Lehigh's engineering school plans to start offering a 10-month master's program in July covering traditional and alternative energy sources, along with some elements of business, management, accounting, and finance. Each student will also participate in an industry-sponsored research project, involving work with members of the trade association. The push to develop new courses is not limited to research institutions. Across the country in Oregon, Lane Community College, in Eugene, has found it can create highly employable graduates by teaching them how to conduct energy audits. Demand for that skill is expected to grow after the federal economic-stimulus measure, enacted in February, set aside $6.2-billion to weatherize low-income homes. However, the biggest problem for universities may be the lack of available professors.
