After the trick or treaters have retired and brushed their teeth, your neighborhood continues to be home to little vampires. Chargers, TVs, computers and other electronics on standby suck energy without a purpose, but at a cost. Good Magazine estimates that a plasma TV in active standby costs an average $160 per year. Use Halloween as a reminder to unplug electronics on this list and give copies to neighbors.

Next, we look forward to carving this CFL shaped pumpkin from Ready Made Magazine, an especially important reminder as upcoming Daylight Savings Time means earlier nightfall. Go ecomaniac and light your pumpkin with an LED. (Image: Flickr/oskay)
