On May 22, 2022, I began an experiment. I unplugged everything in my apartment, with the goal of drawing zero power from the electric grid for one month. I had no idea how I would make it past a few days.

Nevertheless, I opened the main circuit, disconnecting my apartment from the grid and committing myself to solving what problems arose as they came. As I type these words in January, I’m in my eighth month. My Con-Ed bills continue to show zero kilowatt-hours.

Ars Technica readers undoubtedly want to know about my equipment. We’ll get there, but first let me share my history, motivation, and constraints.
