If you were trying to write CaCl2, then that is the formula.
If you wanted the name (of what I wrote, not the nonsense you wrote) then it would be calcium chloride. I suppose technically you could say calcium (II) chloride, but that would be rather pedantic; oxidation states for calcium other than +2 are so rare that the oxidation state is usually only specified when it's something other than +2.
Energy has no chemical formula as it is not a chemical.
