No metal actually "turns green", although copper and possibly others develop surface layers that are green when exposed to many natural atmospheres.
Copper turns green when it reacts with sulphur (sulfur) in the air, forming copper sulfide.

Why is pool water green but there is no algae?
Most likely, metals are in your water. If your pH is low (less than 7.0) and you have a heater with copper tubing, or some other source of metals, you may have copper dissolved in your water. Have your local pool supply store test for metals and if the test is positive, use a chemical like "Metal Free" at a rate of one liter per 20000 gallons.
What is a better conducting electricity metal or copper?
Wow, that is a tough question. If you had to look at the periodic table, you will see that copper is in fact a metal :o.
