Building Energy Measuring and Modelling Sankey Diagrams
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.

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.

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.

Making just such a sophisticated system easier to understand is the purpose of a Sankey diagram, which visually summarises the volume and direction of flows through the stages of a process or system. Sankey diagrams have become common in science and engineering to visualise flows of energy and materials. More recently, their use has expanded to.
US Energy Flow Super Sankey — Otherlab
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.
energy efficiency Sankey Diagrams
The Carbon Sankey diagrams show the greenhouse gas (GHG) emissions generated from the consumption of fuel, steam, and electricity entering U.S. manufacturing plants from offsite sources. Offsite energy is used directly for onsite energy generation, production (process energy), or supporting functions (non-process energy).

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

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.

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.

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.
