EIA’s portal compares energy sector in 50 states

EIA’s portal compares energy sector in 50 states

If you’ve ever been curious about energy facts in your state—such as which sector consumes the most energy, or how your state’s electricity prices compare to the rest of the country—the State Portal hosted by the U.S. Energy Information Administration (EIA) is a convenient, user-friendly resource. EIA’s portal compares energy in the 50 states from […]

The United States of Energy

The United States of Energy

Maps of our nation’s energy potential usually display just one source, such as the location of wind farms or the extent of natural gas fields. In an interesting new data visualization, advertising and PR firm Saxum has combined both fossil and renewable energy resources into a map of The United States of Energy. Below are […]

Flow diagrams of U.S. and Western carbon emissions

Flow diagrams of U.S. and Western carbon emissions

The United States emits around 5.6 billion metric tons of carbon dioxide equivalent (CO2e) each year. That’s roughly the annual CO2 exhaust of 1.2 billion cars, according to the U.S. EPA’s Greenhouse Gas (GHG) equivalency calculator, and it’s nearly 20 percent of annual global GHG emissions. U.S. and Western carbon flow diagrams from EcoWest on […]

Go with the flow: Sankey diagrams illustrate energy economy

Go with the flow: Sankey diagrams illustrate energy economy

Energy flows through everything, so it’s only fitting to use flow charts to depict our complex energy economy. Since the early 1970s, the Lawrence Livermore National Laboratory has been producing such graphics, not only for energy, but also for water and carbon dioxide. Technically known as Sankey diagrams, these data visualizations summarize flows through a […]

Wind and ocean currents visualized

Wind and ocean currents visualized

You may not need a weatherman to know which way the wind blows, but the data that climate researchers collect can certainly deliver some beautiful visualizations of the currents constantly swirling in the skies and oceans. Witness the Perpetual Ocean, a project of NASA’s Scientific Visualization Studio. This video, shown below, depicts the flow of […]
