Unlike a film or video, there is no beginning or end to Gerrard’s work. Programmed to correspond to the real time conditions of the actual Nevada site, the work continuously changes over the course of 365 days due to the changing positions of the sun, moon, and stars across the sky. Though modern in appearance, Solar Reserve references historic representations of the sun in its spiral composition, and points to the primacy of the sun as an ancient energy source. By linking past and present, Gerrard explores both the legacy of energy consumption, and the ambiguous future of energy production.
