RENEWABLE ENERGY ART is a fairly new genre that either incorporates renewable energy into the design of the artwork, or utilizes renewable energy to operate kinetic aspects of the artwork. LAGI's approach is a direct response to global climate change and aims to make an explicit intervention at a functional level without compromising aesthetics.
CO2LED
Created by artists Butch Anthony, Robert Gay and Jack Sanders, CO2LED was a temporary public artwork installed in Arlington, Virginia, USA in 2007. The piece was constructed of more than five hundred solar-powered LEDs on rods, each topped with a recycled plastic bottle. CO2LED, which was installed in the middle of a traffic island, exemplifies the way in which solar artworks can sustainably beautify otherwise mundane urban spaces.
