CO2LED promoted the use of alternative energy sources by using nearly 700 solar-powered LEDs (light-emitting diodes) secured to rods of varying heights, each topped with a reused plastic drink bottle. The poles’ slight flexibility, combined with the LEDs’ nebulous glow underneath the ridged surfaces of the plastic drink bottles, created a soft, undulating cloud of light. A native American prairie grass, little bluestem, was planted beneath the poles and stood in contrast to the grid upon which the poles were installed. At the exhibition’s conclusion, all project materials will be recycled. The use of energy-efficient, solar-powered LEDs, rather than conventional incandescent bulbs, has the power to significantly reduce the release of carbon dioxide (CO2) into the environment. Conventional lighting, fueled by power plants which generate energy through burning fossil fuels, requires far more energy than LEDs, resulting in increased carbon dioxide emissions. Being solar-powered, CO2LED produced long-lasting illumination, free of toxic by-products. CO2LED was developed in conjunction with Planet Arlington, a year-round cultural programming initiative designed to explore issues of immigration, globalization and the environment through the lens of the arts and humanities.
