Do resistors have internal energy?
$begingroup$ Yes, resistors will transform electrical energy to heat, which is considered "internal", however, you will not find many treatments of electrical circuits in terms of thermodynamics. The reason for that is because electrical circuits are extremely far away from thermal equilibrium and thermodynamics has very little useful things to say about that.

Do capacitors automatically release their energy over time?
In practice a capacitor has all kinds of non-ideal properties. Capacitors have ''leakage resistors''; you can picture them as a very high ohmic resistor (mega ohm''s) parallel to the capacitor. When you disconnect a capacitor, it will be discharged via this parasitic resistor.
