Books

When I read the phrase Alt-E my first thought is the Alternative Energy Store, so I would assume that you are asking about books that might be in thier bookstore?
If Alt-E is refering to alternative energies in general then you might want to be more specific. The entire universe is full of energy.
But coming back down to good old mother Earth I can speculate that you are refering to alternatives too; coal fired and, nuclear electric power plants as well as petroleum products. Even here on Earth there is an abundant supply of various energies.
Forgive me but, your question is like asking "I need to know about that tree" while pointing at a forest.
Specifics such as; solar, tidal, wind, plasmas, bio mass, bio diesel, and alcohol. Gosh! I could go on and on. Nasa is developing a way to make electricity from fecal matter.
As an engineering student I am sure you already now that energy is never "used up" it merely changes from one state to another. But you want books. Do you know of the Qabbalah? No? Check it out.
