Many power generation facilities, substations, large buildings, etc, have a large grounding grid consisting of 4/0 stranded copper and 10' ground rods, laid on the ground, cad welded or irreversibly burndied together, adjacent to the buildings and connecting anything metal together.
What is the purpose of this?
Does it really do anything other than waste huge amounts of natural resources?
