Sankey Diagram provide an overview of the main energy flows and how they contribute to the global energy balance of a certain territory. It features directed arrows in which the width of these arrows are proportional to the flow quantity. Within a Sankey Diagram, the directed flow is always drawn between at least two nodes (processes). Thus it shows not only flow values but also information about the structure and distribution of the energy balance.

The primary energy inputs enter the left side of the diagram, and are differentiated into several various types of fuel. The right side represents the energy demand/consumption which are divided by sector, and other energy outputs such as export, loss & own use, and transportation.

Racing bar chart helps to visualize the changes in trend over time. This type of chart is very popular as it provides a holistic data story/insight in a concise and easy to understand chart. This chart represents the display of energy supply, energy consumption, and share of renewable energy by country and by fuel.
