Porch lights are great, especially during Halloween.

Ever wondered how much it costs you to leave your computer or porch light on all night?  Here's your answer. Cliff Notes: Turn computer off when not in use, you're bleeding money even if it's in sleep mode.  Leave porch light on (it does wonders for neighborhood safety) but use a compact fluorescent (and a timer, too - then it turn off in the morning and you don't even have to think about it).
