About This Visualization

This interactive Plotly visualization shows energy generation in the United States over time (1990-2015) for different sources and overall. We can see that overall energy generation in the United States has increased from roughly 12 billion Mwh in 1990 to 16 billion Mwh in 2015. The composition of the energy generation mix has changed over time, though:


You can find a link to the cleaned data I used for this visualization here, and to the Python code I used to make the Plotly visualization here. The original data (uncleaned) is the "Net Generation by State by Type of Producer by Energy Source" document on the the U.S. Energy Information Administration website. I downloaded the data on September 17, 2017 at which point it included years 1990-2015; the data has been updated since then.
