Solar energy is converted to wind energy which then drive surface currents.
If any current is PRODUCED in an individual home, like with
a windmill or solar panels, it is direct current (DC).
The current SUPPLIED to homes by the local utility company
is alternating current (AC).
It is in the noble gas group which has a full valence electron shell found in group 18
