I am a Junior in high school and am just starting the college search. I have always wanted to so something with space, and be an astronaut if I could, but, as astronauts take up such a small percentage of any group of people, I have begun to look for other things. Something that has caught my eye and has really interested me is renewable energy production. The thing is that I don't know what degrees to pursue. What I am thinking right now is to get a double major in physics and chemistry, thereby giving myself a very broad basis and understanding of the world. Then, with respect to my graduate degree, I would funnel into an engineering degree. From reading other posts on physicsforums, it seems that for renewable engineering, the three best engineering degrees are chemical, for biofuels, biomass, and the like; Nuclear, for nuclear fission and fusion; and mechanical, "for everything else," as someone said. I am not terribly interested in the nuclear side of things, so I am dropping that path. So I am left with mechanical or chemical engineering, and I, having only taken AP Chemisty and AP Physics C, don't know enough to say which one I like better (I would like to do both). In conclusion, I am a person who has both sides: I really like to learn stuff and know things, but I also, though I am only in highschool and have not been in the field yet, know that I am a producer. The thing I don't know yet is when the wanting to learn too much takes over the practical production side of me. Does trying to get a double major in physics and chemistry, and follow that with a graduate degree in chemical or mechanical engineering, qualify as trying to learn and do too much? If so, what academic path do y'all think I should do? Thanks.
