Lawrence Livermore National Laboratory (LLNL) has released a Sankey diagram for US energy flow in 2018.
LLNL produced the first diagrams illustrating US national commodity use in the mid-1970s. The most widely recognized of these charts is the U.S. energy flow chart. LLNL has also published charts depicting carbon (or carbon dioxide potential) flow and water flow at the national level as well as energy, carbon, and water flows at the international, state, municipal, and organizational (e.g., Air Force) level.
Flow charts, also referred to as Sankey Diagrams, are single-page references that contain quantitative data about resource, commodity, and byproduct flows in a graphical form. These flow charts help scientists, analysts, and other decision makers to visualize the complex interrelationships involved in managing our nation’s resources.
