Hello, /sci/.

I am an undergrad physics and math major and I'd like to focus my career on a field that deals with clean energy, energy storage, geophysics, etc. because I'm a tree-hugger who's scared of climate change, I guess.

I was hoping some Anons in related fields might give some insight as to what it's like and perhaps get some book recommendations. Thanks.

(Not asking for career /adv/ice, just some experiences and reading recommendations)
