The Nation's Energy Portfolio, Visualized

David Roberts shares news of "a new spaghetti diagram from Lawrence Livermore National Laboratory (LLNL) at the Department of Energy."

"Every year, LLNL produces a new energy flow chart showing the sources of US energy, what it’s used for, and how much of it is wasted," according to Roberts.

Roberts also prepares us to have our minds blown, both in how much energy the United States consumes and how much it wastes, classified as "rejected" energy. "Not just some, but almost two-thirds of the potential energy embedded in our energy sources ended up wasted in 2016," according to Roberts's explanation.

Other focuses of Roberts's interrogation of the chart include the changing nature of the nation's electricity grid and a lack of change in the energy consumption of the nation's fleet of private and commercial vehicles.
