Short story

The blackout struck on the hottest night of the year. At 9:17 p.m., every light in Greenhaven vanished. Air conditioners died. Elevators stalled between floors.

The central grid had collapsed under record demand. Neighborhoods with local renewable systems had not. The distinction was stark. Within months, Greenhaven approved the largest energy project in its
