Energy Flow and Generation Insights

The video tutorial explores energy trends in the US and Western states using Sankey diagrams, a type of flowchart that illustrates energy flows. It covers the historical context of Sankey diagrams, including their use by Charles Joseph Minard to depict Napoleon's Russian campaign. The tutorial analyzes US energy trends from 2008 to 2011, highlighting shifts in energy sources and efficiency. It also examines energy flows in Western states, emphasizing California's influence and the diverse energy portfolios of states like Wyoming, Colorado, and Oregon.
