From solar we have solar energy; from wind, tide, nuclear reaction, and even from the ocean ( thermal energy...I forget the name)

Energy is created in the sense of obtaining pre-existing energy. We don't make "new" energy- we borrow it.

Energy comes from the surrounding environment. On earth, we get it from the sun. Humans hardly occupy all the energy in the universe. We don't even make a grain on sand on the mountain.

Energy can neither be created nor destroyed, but it can be amplified or converted into different forms. Energy can change forms, and can flow from one place to another. The total energy needed to support the growing human population is still within, but it is possible that some sources haven't been discovered.
