Stars have various sources of energy, which will be introduced in this chapter. The discussion will be on the global as well as on the local scale, and typical timescales related to the energy reservoirs will be derived. Since we do not wish to interrupt the derivation of the energy equation for stars with lengthy formalisms, we first provide a few thermodynamic relations which will be used extensively later on.
