The Sankey Energy Data Visualization shows energy systems and it’s flows. It provides additional information on each category and is interactive.

After looking through this visualization for a while, I think that it is very effective for representing a basic knowledge of energy flows. I think anyone could look at this data and understand what it means.

At first, while looking at this data it seemed like a lot of lines that I could not tell where exactly they went. Making this chart interactive was a great decision by the makers because it clarifies where the lines are going, and provides additional information.

The only critique I have for this visualization is that I wish it would have provided more information and visuals on energy losses. Maybe a hyperlink with an additional visualization about energy losses and where or when they occur.
