In past years we all heard that efficient solid-state LEDs would allow to decrease the need for new power plants.
In paper published Thursday in the Journal of Physics D, researchers from Sandia National Laboratories argue cheap efficient lighting can increase consumption.
"Presented with the availability of cheaper light, humans may use more of it, as has happened over recent centuries with remarkable consistency following other lighting innovations," said Sandia lead researcher Jeff Tsao.
Comment: America is bathing in cheap electricity, compared to many European countries. To prevent excessive light usage energy tariffs should be increased gradually. It will make migration to energy efficient appliances faster and economically reasonable. It's still hard to convince consumers to buy expensive LED lighting in order to save $10 on electricity bill.
