Instructions

This interactive graphic allows you to explore data from the U.S. Census Bureau and the U.S. Energy Information Administration. The graphic includes data about state consumption of energy broken down by its source and its use. You can see how different states consumed energy to use it for asphalt and road oil, electricity, and motor gasoline. You can also see which states used the most energy from coal and renewable sources.

Use the radio buttons along the top of the screen to toggle between the energy sources and uses, and use the radio buttons on the right side to see different years. You can compare specific states by clicking on them, and a line graph of their energy consumption will appear below the map. You can also download CSV files of the data used for this graphic by clicking on the radio buttons along the top of the screen.


A Note About Sources: Data about the source and end-use of energy per state is from the U.S. Energy Information Administration. Data about state population for each decade and square milage is from the U.S. Census Bureau. Population data from each decade is extended throughout it. That is, the population of a state in 1960 is used for the years 1960-1969; the population of a state in 1970 is used for the years 1970-1979; etc. These numbers together were used to determine energy use per capita. The D3 JavaScript library was used to generate these graphics. This page was styled using Bootstrap.
