Different energy sources can be used, for example a battery, or energy from plug (delivered by the power company).
Yes to all. -- Electrical current in a toaster produces thermal energy, often known as "heat". -- In a light bulb produces light. -- In the wires dangling from eaqr-buds produces sound. -- In a solenoid coil or motor stator produces magnetic forces.
the sun produces thermal energy
Quite often, the word "circuit" is used for an electrical circuit. In that case, the energy is electrical energy.

the mitochondria produces the energy
Fusion produces the Sun's energy .
the sun produces thermal energy
Because a generator extracts energy from whatever is rotating it and passes this (by the electric current it produces) down the circuit to the motor (or light bulb or heater) where it is used. When there is no complete electric circuit, no electricity can flow so no (little) energy is extracted, but when the circuit is closed, electricity does flow and the armature is more difficult to turn.

Salt produces lattice energy
energy
The energy comes from the chemical activity in the battery producing electricity. Chemical activity produces energy by breaking down chemical bonds. See the link below:

a big building that produces energy
The most energy used in a circuit is at the load.
