Alternative source of energy
Hi, this year I am applying for university, undergraduate course. I'm interested in physics and looking for course connected with alternative source of energy, like from new type of batteries to solar energy to nanoenergy. What type of faculty should I attend? I'm not fond of studying energetics, yet I counted on Physical engineering and nanotechnology course (which is then divided to optical engineering or nanotechnology).
Is there any suitable option for me?
I'm not looking for concrete course, just in general.
