The data used for this project is from the website https://www.epa.gov/egrid/download-data and the data is on the electrical power generation in the US in the years 2000,2010 and 2018 which was released on February 22, 2020. The first thing I did was clean the data to keep only the columns with plant name, state,latitude,longitude and generation megawatt hours for each power source.Removed missing value rows and negative value rows of latitude and longitude columns and renamed multiple columns to an appropriate and short name. The Generation megawatt-hours , Latitude and Longitude columns was string type, I converted it to a number type then created leaflet visualization using the cleaned dataset, and made a reactive layout on the shiny dashboard for the users to do a geographic comparisons of the power plants across the US
