The annual Singapore Light Festival recently opened with this year’s theme of “Light and Nature.” Set at the Marina Bay waterfront, the light art installations are created by artists from Singapore and around the world and are made of environmentally-friendly materials. Additionally, many in the community participate in the concurrent “Switch Off, Turn Up” campaign which encourages switching off non-essential lighting. During the 2014 Light Festival, the organizers claimed they were able to save 269,000 kWh of energy or 140 tons of carbon dioxide for three weeks because of the campaign. This is equivalent to providing electricity for more than a thousand housing flats for the same period. This year’s Light Festival will also join the Earth Hour celebration on March 25 by switching off the lights of the art installations for one hour.
