STUDENT ACTIVITIES ON ENERGY CONSERVATION/EFFICIENCY
− Presentations of Case Studies
− Debate competitions
− Poster competitions
− Industrial visits
− Visual Aids
INSTRUCTIONAL STRATEGY
Teachers are expected to lay considerable stress on understanding the basic concepts in energy conservation, principles and their applications. For this purpose, teachers are expected to give simple problems in the class room so as to develop necessary knowledge for comprehending the basic concepts and principles. As far as possible, the teaching of the subject must be supplemented by demonstrations and practical work in the laboratory. Visits to industries must be carried out. Expert from industry must be invited to deliver talks on energy conservation to students and faculty.
