**8.3 Impact of energy efficiency on primary energy and fuel**

Energy supply chain efficiency is a global concern. It is a common misconception that the demand side primarily impacts the energy supply chain. With a detailed breakdown, as summarized in the chapter, it can be clearly observed that each component of the energy supply chain has a significant impact on the overall energy supply chain efficiency. It is also noted that the most critical two components that have significant losses and are impacted highly are the power plant and the end-user equipment/system. We propose to have an improvement in all components. A little improvement in the end-user system or in the utility power plant creates compounded impact throughout the overall chain.
