What are general energy sources?

Specifically, where can you find petroleum, oil, gas, coal, etc,.? I know you can find them underground and stuff, but where in the world, where in the soil, where in the ocean, why does energy produce in "this place" and not the "other place"
Any other information would help…I’m doing a project about California Oil Drilling, just to let you all know…
