Dependent energy sources:

These are the sources in which its value depends on the voltage or current in the circuit and these are indicated with diamond in the network loop.

These are also called as an controlled sources

Voltage dependent voltage source(VDVS):

It will produce a voltage as a function of the voltages elsewhere in the given circuit.

Current dependent current source(CDCS):

It will produce a current as a function of the current elsewhere in the given circuit.

Current dependent voltage source(CDVS):

Its will produce a voltage as a function of the current elsewhere in the given circuit.

Voltage dependent current source(VDCS):

Its will produce a current as a function of the voltage elsewhere in the given circuit.

K is the constant and V1 and I1 are the current and voltage respectively present elsewhere in the circuit.
