In relative terms, the cost of energy has decreased quite dramatically over the past century. In 1900, only 8% of American homes had electricity, compared to 99% in 2006. In 1900, electricity costs were approximately 10 times those of 2006. Energy consumption dovetails with population growth. In this course, you will learn how to better manage energy consumption and improve energy conservation.
