In our school we 've been checking the energy consume since november 2010 and every week we reward each class that has followed the rules on the correct use of electricity in our school. Also we check on the production of litter by our students and we compensate the ones that not produce any trash while having their snacks. Everyone likes the idea of producing less litter; it is difficult though!
