I posted another thread in this forum regarding the possibility of a career in DSP, but I'm also considering a job in renewable energy (solar, wind, hydroelectric, etc.). I graduated in December from a prominent Los Angeles university (which shall remain nameless for the sake of my anonymity) with a B.S. in EE. Would I have to get a Master's to pursue a career in this field? What kind of coursework would I need to take, and is there any way I can study it myself without getting a Master's? Where should I look for careers in power engineering, solar electricity, etc.?
