Flow charts, also referred to as Sankey Diagrams, are single-page references that contain quantitative data about resource, commodity, and byproduct flows in a graphical form. These flow charts help scientists, analysts, and other decision makers to visualize the complex interrelationships involved in managing our nation's resources. In the news Interactive Sankey diagram of the entire energy system Last updated 19 Aug 2022 Cite Share A new and improved IEA Sankey tool is under development and will be launched in the last quarter of 2023.

Sankey diagrams are ideal for visually representing energy balances. This is because an energy balance represents the contribution and flow of various energy commodities (fuels, heat and electricity, i.e. energy carriers in a marketable form) into the different sectors of the economy (e.g. supply, transformation and consumption) in energy units. Sankey diagrams are a data visualisation technique or flow diagram that emphasizes flow/movement/change from one state to another or one time to another, [1] in which the width of the arrows is proportional to the flow rate of the depicted extensive property . Sankey diagrams summarise all the. energy transfers. taking place in a process. The thicker the line or arrow, the greater the amount of energy involved. This Sankey diagram for an electric. The U.S. Manufacturing Static Sankey diagrams show how total primary energy is used by U.S. manufacturing plants, based on EIA MECS data for 2018. The Sankey diagrams show the fuel, steam, and electricity entering U.S. manufacturing plants from offsite sources. Renewable electricity generated onsite is also shown.

A Sankey diagram is essentially just a big arrow, which is labelled to show any changes in energy forms. The arrow will split if the energy changes into more than one energy form. For example, here is the Sankey diagram for an electric light bulb: Sankey diagram of a light bulb We also might label the amount of energy of each energy form. The Sankey diagram is an important aid in identifying inefficiencies and potential for savings when dealing with resources. It was developed over 100 years ago by the Irish engineer Riall Sankey to analyze the thermal efficiency of steam engines and has since been applied to depict the energy and material balances of complex systems. The Process Energy Static Sankey diagram shows how energy is used directly for production by U.S. manufacturing plants, based on EIA MECS data for 2010. Click on the Full Sector, Onsite Generation, and Nonprocess Energy thumbnails below the diagram to see further detail on energy flows in manufacturing. The Interactive Sankey Diagram provides more than 20 years of energy data for more than 140 countries and regions worldwide and are available as interactive data visualization that can tell a global energy story over several decades and give the user better insight and understanding.

Whenever an arrow splits in a Sankey Diagram, it means that energy has transferred to different forms. The widths of the new arrows (new energy forms) must add up to the width of the starting arrow. This is the Law of Conservation of Energy in action. Some of the input energy will be transferred to heat energy which is 'wasted' - we don't need. The Sankey diagram is an important aid in identifying inefficiencies and potential for savings when dealing with resources. It was developed over 100 years ago by the Irish engineer Riall Sankey to analyze the thermal efficiency of steam engines and has since been applied to depict the energy and material balances of complex systems.
Depict National-Scale Energy Systems. Lawrence Livermore's flow charts illustrate the complex relationships among energy, water, and carbon to help people understand the structure of the nation's energy system.. (Sankey diagrams date back to the 1800s and were used during the industrial revolution to map the flow of raw materials and. Summary. The Sankey diagram is an important aid in pointing up inefficiencies and potential for savings in connection with resource use. This article, the second of a pair, examines the use of Sankey diagrams in operational material flow management. The previous article described the development of the diagram and its use in the past.

The energy flow (Sankey) diagram provides information about the energy transfers to or from the system while it gives no information about the changes in the quality of energy. Therefore, the Grassmann diagram, which gives quantitative information related to the share of the exergy input/output to/from the whole system, is drawn in Fig. 13. Technically known as Sankey diagrams, these data visualizations summarize flows through a system by varying the width of lines according to the magnitude of the commodity in question. In this deck of slides, I offer up some of Sankey diagrams that illustrate energy trends in the United States and Western states.
