InstructorThe pursuit of independence ultimately led Jay to the field of Renewables. Coming from a career as a mountain guide and educator, it only felt right to understand the world away from the grid. A workshop with SEI laid the foundation, and from there things just fell into place. Eventually, partnered with his wife Lena, they founded Nunatak Alternative Energy Solutions based in the Elk Mountains of Crested Butte, Colorado. Specializing in remote off-grid system installation and design, the mountain environment taught them many lessons in dealing with harsh environments. The challenge and creative problem solving involved in design and implementation of these systems has made a passion out of a career. Being a contract workshop instructor for SEI since 2006 has allowed Jay to dovetail his time as an educator with practical real-world experience. Time off is spent outside: hunting, skiing, running rivers, or just letting his daughter teach him a thing or two about the world.
