Sankey Charts: Visualizing Energy Flows and Resource Allocations

Sankey charts are a type of flow diagram that are used to display the flow of energy or resources between different nodes in a system. These charts are often used to visualize the efficiency of a system and to identify opportunities for improving resource allocation.

How to create a Sankey Chart

To create a Sankey chart, you will need to have a flow or resource data that includes the start and end points of each flow or resource, as well as the amount of flow or resource that passes through each node. You can then use a spreadsheet program such as Microsoft Excel or Google Sheets to create the chart.

To create a Sankey chart in Excel, follow these steps:

1. Enter your data into a spreadsheet. Include the start and end points of each flow or resource, as well as the amount of flow or resource that passes through each node.
2. Select the data that you want to include in the chart.
3. Go to the “Insert” option in the main toolbar and select “Sankey Chart.”
4. Choose the chart type that you want to use (e.g. “Sankey Flow Diagram” or “Sankey Bar Chart”) and adjust the chart settings as desired.
5. Customize the chart by adding shapes or text boxes, as necessary.
6. Save the chart.

Applications of Sankey charts

Sankey charts are a powerful tool for visualizing energy flows and resource allocations. They can be used in a variety of applications, including:

1. Energy audits: Sankey charts can be used to visualize the energy flows within a building or system, allowing you to identify areas where energy is being wasted.
2. Resource allocation: Sankey charts can be used to visualize the flow of resources between different departments or teams within an organization, allowing you to identify opportunities for improving resource allocation.
3. Supply chain management: Sankey charts can be used to visualize the flow of goods or services between different suppliers or customers, allowing you to identify areas where improvements can be made.
4. Environmental impact assessments: Sankey charts can be used to visualize the flow of pollutants or other harmful substances within an ecosystem, allowing you to identify areas where pollution can be reduced.

Conclusion

Sankey charts are a powerful tool for visualizing energy flows and resource allocations. They are easy to create and customize, and can be used in a variety of applications to improve the efficiency of a system or reduce environmental impact. By unlocking the power of Sankey charts, you can gain new insights into your flow or resource data and identify opportunities for improvement.
