Part One: Pondering while Eating Toast: Bread Crumbs to Utility Pole.
This journey traces our electrical power to its source – in three parts.
How does the ubiquitous energy that we take for granted come to our homes? Where does it start? How does it happen? What’s all that stuff up there on the “utility” poles? In my case a 35 mile (56 km) drive up to Tomkins Cove, NY, reveals these two enormous 475 foot (148 m) towers supporting 12 fist size cables across the Hudson River – freshly energized with something like 500,000 volts.

Walking Sandy Paws, the dog, most mornings, I find myself looking up at the utility poles with their strings of wires overhead, – everywhere – seemingly not much different than 120 years ago in the big cities. What’s up? So I grabbed my camera and did some investigating, starting with my morning toast.
…So, right outside our home, a pole supports a 7,200 volt feed wire (it may be as high as 13,200 volts,) and transformer which steps voltage down to 120 volts and connects directly to our house.
Disclaimer: Not being an electrical engineer or public utility employee, some values and circumstances may be slightly different than stated, but should give a general idea of the actual grid. Any system or statistical corrections will be most appreciated.
