Course Overview

Description: Energy is a vital component of modern society. Much of the general population believes that the energy sources we depend on are perpetual. While people believe that energy use is the culprit for environmental damage, they are not aware of the methods and principles by which energy conversion devices operate. This general education course will provide you with the necessary knowledge and information on the main operating principles of devices/appliances that are in common use, and information on how to make the right decision in selecting the most energy-efficient and economical choice. These devices are day-to-day appliances such as refrigerators, washers and dryers, ovens, etc., and home heating or cooling and transportation choices. The course also provides necessary information on heating furnaces, insulation, doors and windows, lighting, and air conditioning principles. The objective of the course is to expose you to energy efficiency in day-to-day life in order to save money and energy and thereby protect the environment. I hope the information in this course will help you become an environmentally responsible individual of this Global Village.
