Perhaps I am dense but I do not understand this. There is a wire carrying electricity and windmills creating electricity. Is Mr. Slye saying that because the electricity is designated for export that either technology or people have decided it will not be carried on those wires? If it is not to be carried on those wires, will there be a parallel set of wires to carry electricity for export? Why do we need two sets of wires instead of one?
