Renewable Energy Technology
The Renewable Energy Technology/ Electronic Engineering Technology (RET/EET) program offers a comprehensive premier workforce training in Renewable Energy Technology, leading to a 9-month Certificate and/or a 2-year Associate of Applied Science (AAS) degree.
Students gain an opportunity to practice wind tower climbing, work 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 field of renewable energy is driving a 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 industry.
