Simply presenting data can still be biased. For example you can choose what metrics to show or you can choose to omit data (deaths for solar and wind) in order to make your preferred choice more palatable. I'm not accusing the authors of doing this because I don't know much about this field, but it's worth being aware that even raw data can be biased.
