In the current situation, the number of energy sources in the world become less because of inefficient usage and the lack of realization on energy saving. Consequences from overusing energy include global warming problems. To encourage and promote efficient use of energy and energy reduction, this research was to improve energy awareness through 3D computer animation. The animation was created in the form of video animation format and has production process as follows: 1) Pre-production: problem defines, story board, turntable animation and backdrop design 2) Production: 3D model character, shading and texturing, lighting and shadowing, rendering and compositing and 3) Post-production: combining the story, inserting voice record and sound. A statistical examination, the research validation was evaluated by 5 experts and resulted in good level (= 4.11, S.D. = 0.64). When testing understanding and perspective on animation media with the sample group of 50 students from Sripatum University Chonburi Campus, the result of the survey that conducted before presenting the campaign (pre-test) was in moderate level (= 3.32, S.D. = 0.56) while the result that conducted after presenting the campaign (post-test) was in very good level (= 4.67, S.D. = 0.48). Therefore, the 3D computer animation could help samples understand more about importance of energy reduction.
