OREANDA-NEWS. June 15, 2012. Flooded in green light for the United Nations Conference on Sustainable Development in Rio de Janeiro, the Christ the Redeemer statue on Corcovado Mountain is now a beacon of sustainability, visible for miles around. Three-hundred high-efficiency cutting-edge LED projectors from Siemens' Osram subsidiary are illuminating the conference symbol, which is one of the New Seven Wonders of the World. To mark the world-famous statue's 80th anniversary in 2011, Osram equipped the monument with state-of-the-art lighting technology. The new LED system is reducing the energy needed to light the nearly 40-meter landmark by more than 75 percent. Solutions that combine high-efficiency lighting products with light management systems can yield energy savings of up to 80 percent. Artificial lighting accounts for some 20 percent of world electricity consumption. All around the United Nations conference, a large number of Siemens projects are demonstrating how technologies already available today can make humanity's further development both sustainable and energy-efficient.
