Here’s an interesting graphic showing the amount of energy consumed by some common appliances when not in use, although the distinction between “passive” and “active” loads also seems unnecessary and distracting. Also, this phenomenon is typically called phantom load not “vampire load,” as the artist has dubbed it, after a less common term for wall-warts. Perhaps this even inspired google’s little contribution towards energy frugality last Halloween: The Haunted House? In any event, be sure to multiply the listed costs of these little suckers by a factor of 2 or 3 to to more accurately reflect bills in Cambridge.

Also while surfing this weekend I came across another infographic from progressive magazine GOOD. This one’s a sort of decision tree, comparing water consumption for daily activities. Keep in mind though, that things are not quite as simple as some would like to make them out to be. While it may actually take more water to grow an apple, the devil is in the details. If you’re biting into a Jonagold from Stow in September, then much of the water was rain, and very little gasoline went into transporting it. On the other hand, an orange from a field irrigated with scarce water in California or Florida has a lot of embodied energy. As always caveat emptor.
