Energy conservation节约用能 Not such a bright idea听起来像个馊主意 Making lighting more efficient could increase energy use, not decrease it 让照明变得更加高效会促进而并非减少能源的消耗Aug 26th 2010 Less is more节约了？　浪费了！SOLID-STATE lighting, the latest idea to brighten up the world while saving the planet, promises illumination for a fraction of the energy used by incandescent or fluorescent bulbs. A win all round, then: lower electricity bills and (since lighting consumes 6.5% of the world’s energy supply) less climate-changing carbon dioxide belching from power stations.必威体育精装版的既可照亮世界又可保护地球的方案晶体管照明仅仅利用常见白炽灯或荧光灯的一部分能源就可提供照明。这听起来好像可以一箭双雕：即可削减电费帐单又可减少从发电厂中不断喷涌而出的温室气体二氧化碳（照明占据了地球6.5%的电力供应）。Well, no. Not if history is any guide. Solid-state lamps, which use souped-up versions of the light-emitting diodes that shine from the faces of digital clocks and flash irritatingly on the front panels of audio and video equipment, will indeed make lighting better. But precedent suggests that this will serve merely to increase the demand for light. The consequence may not be just more light for the same amount of energy, but an actual increase in energy consumption, rather than the decrease hoped for by those promoting new forms of lighting.但事实却并非如戏。历史上可是有前车之间的。作为在电子表和视频或音频设备的面板上闪烁不止的发光二极管的高效版本，晶体灯确实可以提供更优质的照明。但是历史告诉我们这个应用将只会增加对光的需求。结果不会仅仅是等量的能源造就更多的光明，而会是能源消耗的实际上升，而非那些推广新的照明方式的人所期望的减少。The light perceived by the human eye is measured in units called lumen-hours. This is about the amount produced by burning a candle for an hour. In 1700 a typical Briton consumed 580 lumen-hours in the course of a year, from candles, wood and oil. Today, burning electric lights, he uses about 46 megalumen-hours—almost 100,000 times as much. Better technology has stimulated demand, resulting in more energy being purchased for conversion into light.人的肉眼可以感受到的光可以用流明时这一单位计量。1流明时约等于一支蜡烛燃烧一个小时所产生的光。 在1700年一个正常的英国人在一年中通过蜡烛、木材和油消耗580流明时。而今天由于电灯的应用，他将消耗46 百万流明时，差不多是从前的十万倍。更好的技术刺激了需求，导致了对转化为光明的能量的更多消耗。That, at least, is t
