Countries and companies began to innovate ways to increase energy efficiency in 1973 when fears of an oil shortage spread panic in the West and Japan.
Since then, energy efficiency has helped reduce energy use. In addition, it has become the cheapest and easiest way to curb greenhouse gases (GHGs) that lead to climate change. Finding ways to improve energy efficiency is a high priority among many researchers, engineers, and scientists.
Human beings always have used energy in some capacity. Prior to the 1700s, human labor or farm animals performed most agricultural...Read more
