Some loose suggestions, without any other background than general interest from my side:
What is energy management now, and what will it be 5 years in the future? At what position and type of work do you see yourself in, in 5 years?
Undoubtly, as in many engineering areas, things will happen in 'energy area' the next years, perhaps faster or, as most usual, much slower than we imagine?
Better perhaps to think 'type of job related' and contact possible employers directly as an approach, both to sound out opportunities and feedback on possible future, and where you also geographically can limit or expand your target.
