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 Western Governors’ Association (WGA) calls the West the nation’s “energy breadbasket,” owing to the region’s vast and diverse energy resources. In its most recent report, “The State of Energy in the West,” the WGA provides a comprehensive survey of conventional and renewable energy as part of its year-long focus on energy. In a previous […]
The 50 states pursue different paths to supply energy to their residents, with some heavily reliant on coal, others dependent on hydropower dams, and many tapping a broad portfolio of sources. I described this diversity of approaches in previous posts on energy flow diagrams and a map of the “United States of Energy.” In this […]
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 […]
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 […]
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 […]
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 […]
