Necessity is the mother of invention.  A need encourages creative efforts.  The history of world is the history of mankind determined from various disciplines such as archaeology, genetics, anthropology, linguistics etc.  Sun has always been the source of energy in the form of heat and light. Ability to produce fire and use it to burn biomass were the main milestones in the history of mankind. Man depended on the power from manual labour and animals.   Invention of watermills and then windmills emerged as the means to utilize natural sources of energy.  The pace of inventions and discoveries of conventional and renewable sources of energy and their usages picked-up in last few centuries.  The ways of transportation and communication were evolved.  In the last few decades, environmental concerns and climate uncertainty are compelling the trends of usage of environment friendly sources of energy.
