Having done BSc in Electrical Engineering I applied to American schools looking for something in Renewable Energy. I got admission into UMass amherst Ms in Mechanical Engineering (Wind Power Energy Concentration). What I want to be guided on is it the right thing to do going into mechanical engineering degree. I want to do something different but is it normal for me to take this path? Will I struggle too much with new concepts?

I have also gotten into Wayne State Uni MS in Alternate Energy Technology but I am not so sure about it.
