Data

The data I used was from this website: https://www.eia.gov/electricity/data/state/

Make sure to choose the spreadsheet that says "U.S. Electric Power Industry Estimated Emissions by State".

Here is a direct link to the spreadsheet if you prefer: https://www.evl.uic.edu/aej/424/annual_generation_state.csv

There is no need to make any changes to the file outside of RStudio. In fact, I make several modifications to the data in my source code. I then turned the data into stacked bar charts, line charts, tables, and heat maps.

This is what the original spreadsheet should look like.
