Last week kicked off “The Hunt: 11 Days of Doing.” The campaign uses cellphones to deliver daily challenges to teens so they can do eco-savvy deeds in their local communities.

Today’s secret mission, which focuses on energy and the environment, comes with a video shoutout from the "Twilight" saga’s Tinsel Korey. Tinsel encourages people to “do something” by unplugging appliances that aren't in use. Check out the video below:

Energy used by appliances when they are plugged in but not being used is called “vampire energy” (though Tinsel likes to call it “wolf energy”) and nationally accounts for more than $10 billion in annual energy costs. Other challenges for today include searching for five ways to conserve water in your house and turning the air conditioning settings to no lower than 78 degrees Fahrenheit. Participants receive awesome prizes like scholarships, Lenovo Ultrabooks and a trip to the 2012 Do Something Awards in LA.

So far, kids participating in The Hunt have completed a number of green-focused challenges, making a measurable impact:

  • 118,416 cans and bottles were recycled in one day
  • 20,463 pieces of litter were cleaned up in local parks
  • Almost 900 people went meatless for a day, saving an estimated 500+ pounds of beef

The Hunt is almost ready to wrap up, but you can still sign up for the campaign at the DoSomething website or text ‘HUNT’ to 38383 to get started. Or check out the website to find more challenges.
