Energy-saving LEDs 'will not save energy', say boffins • The Register
Federal boffins in the States say that the brave new future in which today's 'leccy-guzzling lights are replaced by efficient LEDs may not, in fact, usher in massive energy savings.
This is because, according to the scientists' research, people are likely to use much more lighting as soon as this becomes practical. The greater scope for cheap illumination offered by LEDs will simply mean that people have more lights and leave them on for longer.
After twenty years of enduring dark corners in the kitchen I put up two new rows of spotlights - these are additional lights - and today bunged in ten 3w LED lights. I figured they are going to be on everyday for most of the day so the investment will pay for itself. So the boffins have proof from me...
According to Tsao and his colleagues at Sandia, the fraction of gross domestic product spent on lighting has remained constant as candles were replaced by oil lamps, then again in the transition to the gaslight era, then yet again with the arrival of electric lighting. What changed with each of these innovations was that lighting became more and more common.
(UPDATE -24 hours later - one of the LED bulbs has failed and fused the house...)
