What Colleges offer this degree?

I am interested in the field of Solar Energy, I am not really sure what the title or name of the degree is but I figured it has to be something like Alternative Energy Engineering or Solar Engineering. I'm having a hard time on Google trying to find what colleges offer something like this, I would really like to stay close to my home state in Texas. Would really appreciate if you guys could give me a grasp of where and what I need to do to find more information on this career
