When Ferris High School students Mark Balabanov, 17, Colin Calvert, 18, and Irina Peregudova, 15, got a class assignment to make an energy preservation video for Avista, they were all in. Multimedia teacher Joan Conger used Avista’s annual Every Little Bit video contest as a class assignment. The contest asks high school students to make short videos about energy preservation practices and why they are important to the environment.
