This paper presents a detailed survey of global energy delivery and smart grid approaches. Particularly in the sense that shows the impacts on the production of energy resources globally. How can energy losses be reduced, primarily by implementing smart grid approaches? Power transfers and reduction of energy sources can be made by smart grids with information technology (I.T) such as sensors digital meters and communication networks.  Energy from photovoltaic and wind power are some of the energy delivery systems that have gained attention since they are cheap and environment-friendly and do not emit greenhouse gas. Presently available grid is insufficient to serve future systems. For this reason, an intelligent grid system is required to support future needs for society. This paper expounds on the impacts of the existing power delivery system and suggests a smart grid for global energy delivery on a better management system.
