You can get the data used in the project with the links provided above. The data is about the electrical power generation in the US from the years 1990 to 2019. The data was released towards the end of the year 2020.
There were a few things that had to be done to data in order to clean it up. I had to remove some types of energies, and remove the columns that had empty data. Also the column with the megawatts per hour, it was originally a string and I had to convert it to numbers.
