Sankey charts are an innovative way of visualizing and understanding energy flows. Developed in the 1840s by Scottish engineer William Senior-Gaetano Sankey, these charts have since been widely used in fields such as sustainability, economics, and healthcare to analyze and optimize energy consumption. In this article, we will explore the power of Sankey charts and show you how to create and apply them to make impactful decisions.

Sankeys laws

Sankey charts are named after William Senior-Gaetano Sankey, a Scottish engineer who discovered the laws governing the flow of energy between different systems. He developed two laws that are still used today in the creation of Sankey charts:

1. Law of conservation of energy: This law states that the total energy in a closed energy system remains constant over time.
2. Law of energy transformation: This law states that energy can be transformed from one form to another, but the total energy in the system remains constant.

With these laws, Sankey charts can be used to visualize and understand the flow of energy between different systems, and to identify opportunities for energy efficiency and conservation.

Creation of Sankey charts

Sankey charts are created by connecting nodes, each representing a type of energy source or system, and connecting arrows that indicate the flow of energy between them. The chart shows the total energy input and output for each node, and the directions in which energy flows between them.

Sankey charts are particularly useful for analyzing energy usage in industries and businesses, as well as in overall energy consumption. By visualizing energy flows, it is possible to identify opportunities for conservation and efficiency improvements.

Applications of Sankey charts

Sankey charts have a wide range of applications, including:

1. Energy efficiency: Sankey charts can be used to analyze energy usage and identify opportunities for efficiency improvements. For example, a company might use a Sankey chart to identify which processes consume the most energy, and determine ways to optimize these processes.
2. Sustainability: Sankey charts can be used to analyze the sustainability of a product or system. For example, a manufacturer might use a Sankey chart to track the flow of energy in their supply chain and identify opportunities for reducing energy consumption.
3. Economic analysis: Sankey charts can be used to analyze the flow of energy within an economy. For example, a government might use a Sankey chart to study energy consumption patterns and identify areas for policy intervention.
4. Healthcare: Sankey charts can be used to analyze the flow of energy within the healthcare system. For example, a hospital might use a Sankey chart to track the flow of energy between different departments and identify opportunities for energy efficiency improvements.

Conclusion

Sankey charts are a powerful tool for visualizing and understanding energy flows, and can be used in a wide range of applications to make impactful decisions. By connecting energy inputs and outputs and analyzing the flow of energy, it is possible to identify opportunities for efficiency improvements, sustainability, and economic analysis. We hope that this article has inspired you to use Sankey charts in your own projects and endeavors.
