Is Green Really "Green"?

Is Green Really "Green"?

Green chemistry is becoming more commonly practiced with each passing day. In this study, an analysis of energy efficiency is evaluated from the standpoint of the total resources invested, risks involved, and total waste produced, for the production of so labeled green energy. Generally, it is understood to have almost 40% loss in efficiency when a primary source of energy (coal, petroleum) is converted to a secondary source of energy (electricity). A case study of energy efficiency of biodiesel production from waste oil and plant waste will be presented in this study.
