2. Forget lawnmowers. A Pennsylvania school district has found a rather old-fashioned way to save some green: Employ hungry sheep. Workers for the Carlisle Area School District used to spend six hours a week mowing a field filled with solar panels at Wilson Middle School, but woolly mammals now handle those duties, saving the district as much as $15,000!

    *It was revealed to us during yesterday’s editorial meeting that one of The Week staff members had a lawn-mowing goat while growing up. Genius!
