Detail Energy conservation: Not such a bright idea   Oleh:  [s.n] Jenis: Article from Bulletin/Magazine Dalam koleksi: The Economist (http://search.proquest.com/) vol. 396 no. 8697 (Aug. 2010), page 66.

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. 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.
