Renewable Energy Technology
CGCC Photo/Michelle Bose
The Renewable Energy Technology (RET) program offers premier workforce training through a 9-month Certificate and/or a 2-year Associate of Applied Science (AAS) degree. This nationally-recognized program prepares students to work with automated electronic technologies in a variety of industries including renewable energy, advanced manufacturing, and engineering.
Students practice tower climbing, working in a confined space, and rescue techniques. The climbing tower on the The Dalles Campus is an essential part of the first-year RET curriculum.
The renewable energy field is driving rapid growth in technology, creating jobs which will require thousands of highly skilled workers over the next two decades. Building on a solid foundation in math, writing, and computers, our students learn in a rigorous, hands-on environment and are well-prepared to tackle the challenges of this and other technology-focused industries. RET graduates work for Siemens, Bonneville Power Administration, Portland General Electric, SolarWorld, Insitu, Sagetech, and Cloud Cap Technology, to name a few.
