Blackouts hardly make you think of going green, but this week, procrastinators, we’re about to change all that. At www.blackle.com, you can do your thing for the environment by getting search-savvy. The Google-powered site features a darkened screen, with your queries-not your background-getting the light. Blackle’s claim to environmental fame is a decreased amount of wattage compared to the traditional, white-based site. Even though the difference may not seem significant, as the site claims, it is a small but significant step in being more energy-efficient and environmentally conscious. So, this week, when you feel like procrastinating, try doing it in the dark.
