Intriguingly, it probably hasn't fallen that much in terms of total energy spend. At every step of the way on the path to increasing efficiency, we didn't focus on saving; rather, we've increased the amount of light in public and private spaces. Where in the past a dimly lit room or alley might have been fine, you'd use intense light sources nowadays.
- VLM 10y agoI had fifteen 60 watt bulbs in my basement lab/workshop on tracks and that's 900 watts. And in my living room I had two three hundred watt torchaire style halogen bulbs, that's 600 watts. I don't think my house was unusually bright. My LED replacements are actually brighter in terms of lumens which is very nice, but only recently could I theoretically afford 1500 watts of LEDs. I mean there was an early adopter time not long ago when LED bulbs were like $30/watt. I think 1500 watts of modern LEDs would be quite the searchlight. An eighth of a million lumens seems within reach for one fifteen amp AC power cable. That's about a square meter of bright noontime sunlight, which isn't so bad.
