Is this outlet safely grounded?
I was replacing one of the outlets in the kitchen in my home and I noticed the ground wire goes to a screw on the back plate of the outlet box, and a green ground wire runs from the same screw on the back of outlet box, to the receptacle. I opened a few more outlets in the house and noticed that they are all wired that way.
I'm no expert, so I was curious if these outlets are considered grounded properly or not. Or if I should go into every outlet in the house and run the ground wire directly to the receptacle and ditch the green wire to the outlet box.
Thank you.

Answer:
They are grounded.
One reason the person who used the insulated ground wire instead of bare wire, is that the bare wire can sometimes make a short with the hot wires if not placed correctly in the box.
Will need to test if the bare ground wires are correctly connected back to the panel to be sure of ground. One simple test is to use a multi meter to see if you get 120v(or local) between the hot and ground wire or the box.
