Depends on what you are wiring. Green is a common color used for ground. Sometimes it is just a bare copper wire.

What color can an underground conductor not be?
an underground conductor can be any color except white, grey or green.
What two colors may be used for the ground conductor neutral?
What two colors may be used for the ground conductor (neutral)
What is the common wire color?
green <<>> In North America the common (neutral) conductor is white. The ground wire is green or bare depending on its location in the system.
What are the faults in the cable?
Cable faults are normally categorised as (a) conductor-to-earth (ground) faults, (b) conductor-to-conductor faults, and (c) conductor-to-conductor-to earth (ground) faults. In addition to that, we can categorise them by whether they are 'high-resistance' or 'low-resistance' faults.
Can ground conductor use as a neutral conductor in a house wiring?
No. Absolutely not. The ground conductor is not rated to carry constant current flow. It is only rate to carry fault current flow.
What is the difference between a ground conductor and a ground electrode conductor?
# A ground electrode conductor is a conductor that originates at the neutral or equipment ground buses in the main service entrance panel board or separating derived system (e.g. isolation transformer) # A ground electrode is a item that is in contact with the earth (e.g. Building metal frame, underground continuous metallic water pipe etc...) # A ground conductor is a conductor that is used to keep an electrical system continuous. Ground conductors are required, by code, in all PVC conduit runs. Ground conductors are also used to keep all metallic components of the installation at the same zero potential to overcome mechanical connections that would not carry a fault current back to the supply distribution panel.
A conductor directly connected to the Earth?
GROUND
Is ground a good conductor?
of electricity yes
How are the live neutral and ground wires connected to a duplex grounding type receptacle?
The black "hot" conductor goes to the brass coloured screw. The white coloured conductor goes to the silver coloured screw. The bare ground conductor goes to the ground green coloured screw
What does an electric current continually seek a pathway to?
An electrical current continually seeks a pathway to ground.
Is green ground in an extention cord?
Yes, the green conductor is the colour of the ground wire in an extension cord. The black wire is dedicated to be the "hot" and the white conductor is the neutral.
In the electrical system of the US what is the difference between the neutral and the PE Ground?
US NEC: The neutral conductor is an insulated grounded conductor used as the current return in a circuit. The color designation for neutral is white. The protective ground (PE, protective - earth) is a non-insultated grounding conductor used to shunt fault current to ground, tripping the protective device. The color designation for PE ground is green. Neutral and PE ground are tied together at the distribution panel. PE ground is also connected to a solid earth ground, such as grounding rods driven into the earth. Downstream of the distribution panel, PE ground is never used to carry operational current. Any current flow on PE Ground, other than parasitic current, is considered a ground fault, which must be corrected. In fact, GFCI (Ground Fault Current Interrupting) breakers will trip when neutral current does not match hot current, an indication of PE ground current flow.
