Sankey charts are a type of flow diagram that can be used to visualize the flow of energy, materials, or other types of inputs and outputs in a system. They are often used to identify opportunities for efficiency and to design systems that are more energy-efficient or sustainable. In this guide, we will explore the basics of Sankey chart creation, as well as some applications of Sankey charts in different fields.
What Are Sankey Charts?
Sankey charts were originally developed by the economist and social reformer Rudolph Sankey in the late 19th century. They are a type of flow chart that uses ovals and arrows to represent the flow of inputs and outputs in a system. The ovals represent the sources or inputs of energy or other inputs, while the arrows represent the flows of energy or other outputs.
Sankey charts can be used to represent a wide range of energy systems, such as power plants, industrial processes, or transportation systems. They can also be used to visualize the flow of other types of inputs and outputs, such as materials or water.
How to Create a Sankey Chart
To create a Sankey chart, you will need to gather data on the inputs and outputs of the system you are studying. This may involve collecting data from various sources, such as government reports, industry studies, or scientific research.
Once you have collected your data, you can use a spreadsheet program or a specialized Sankey chart software to create the chart. The software will allow you to input the data into the chart, and will generate a visual representation of the flow of inputs and outputs.
Some tips for creating a Sankey chart include:
- Make sure to clearly label the ovals and arrows in the chart to avoid confusion.
- Use a color scheme to differentiate between different types of inputs and outputs.
- Consider adding comments or notes to the chart to explain any unusual or unexpected patterns in the data.
Applications of Sankey Charts
Sankey charts are widely used in a variety of fields, including energy, transportation, and manufacturing. They can be used to:
- Identify opportunities for efficiency or sustainability. For example, a Sankey chart for a manufacturing process might be used to identify areas where materials could be reused or recycled, or where energy could be saved.
- Evaluate the sustainability of a system or process. For example, a Sankey chart for a power plant might be used to assess the greenhouse gas emissions associated with the operation of the plant.
- Design new systems or processes that are more efficient or sustainable. For example, a Sankey chart for a transportation system might be used to evaluate different options for improving the efficiency of the system.
In summary, Sankey charts are a powerful tool for visualizing the flow of energy, materials, or other inputs and outputs in a system. They can be used to identify opportunities for efficiency or sustainability, evaluate the sustainability of a system or process, or design new systems or processes that are more efficient or sustainable. By understanding the flow of inputs and outputs in a system, we can make more informed decisions about how to improve the efficiency or sustainability of that system.
