From Wire to Light

This reading sits behind one of the Chain panels: a process traced trade by trade from its first step to its last. The chain is the museum's argument that nothing in a city is made by one person.

The panel text

1. Generation. A plant — gas, solar, wind, nuclear — turns motion or light into current. The nuclear technician, the wind technician and the solar installer all begin here. 2. Transmission. Lineworkers hang the high-voltage lines on the towers. 3. Substation. Transformers step the voltage down; the substation electrician keeps them alive. 4. Distribution. Poles and underground runs to the street. 5. Service. The meter, the service entrance, the panel — the electrician's first job on a house. 6. Branch circuits. Conduit, wire, breakers, devices, to the NEC. 7. The switch. A person touches it. Light. 8. Behind the light. The data center technician's racks, the HVAC technician's chillers keeping them cool, the elevator mechanic's controller waiting for the button.

Everything in a city is on the far end of a wire. Every program on the Power Systems and Renewable Energy pathways sits somewhere on this line.
