[ale] Microsoft tries to reverse Vista's Impact on the environment

[Jim Kinney]

yes. AC power is "weird". Fluorescent lights are similar to a spark
gap and are thus very "reactive". While the load at the lamp is low,
the generator must create extra power for the reactive
characteristics. In short, CF lights are less power hungry than
ordinary incandescents but the label on the box is misleading. A 10W
use at the bulb requires 14-16W "at the pole" because of the timing
fun in AC circuits.
