How many blues musicians does it take to replace an inefficient light bulb with an energy-efficient one?
Five: One to replace the light bulb, and four to play sad songs about how the old, inefficient bulbs went away, and maybe they weren’t so bad after all.

When using your laptop computer at home, put the battery charger (an AC adapter) on a power strip that can be turned off. The transformer in the charger draws power continuously, even when the laptop is not plugged in.
