Much is lost in the initial generation of electricity. And much is lost through the use of inefficient devices, like incandescent light bulbs that heat up a filament to produce light.
But power is also lost in between, on the grid, as it is carried along hundreds of miles of wires, repeatedly shifted between different voltages, and converted from AC to DC and back, all in the split second between the time it enters the grid and the time it powers your computer.
How much power is lost on the grid?
