奥巴马宣布的新清洁能源方案,不仅是美国首次对发电厂碳排放设立国家标准,更被视为是美国“史上最强的”重大减排举措。近年来,美国的建筑物变得越来越“冷”了。从使用产生热量的白炽灯,到使用发光二极管(LED),这一转变,使得美国的照明能耗减少了85%。美国能源部能源效率与可再生能源办公室首席副助理国务卿David Friedman Obama announced the new clean energy program, not only the United States for the first time to establish national standards for carbon emissions from power plants, but also as the United States “the strongest ” major emission reduction initiatives. In recent years, buildings in the United States have become more and more “cold”. From the use of incandescent lamps that generate heat to the use of light-emitting diodes (LEDs), this shift reduced the lighting energy usage in the United States by 85 percent.
