Is my plot easy to understand what it is showing?

[jammmmmmieblak]

I’d like some help to understand whether or not my graph is easy to understand and whether there was anything I could do to make it any easier to read at a glance.
The graph is meant to show the average production of each power station per source.

Data is gathered from the global power plant database:
http://datasets.wri.org/dataset/globalpowerplantdatabase

I have created another field to complete this plot, the average generation of each power source, Generation per Power Source.

Looks very clear and easy to understand.

Chart is easy to read. Distribution of power is not unexpected but would also be interesting to know the unit of power (kwh, Gwh?) and the sample size

Looks clear and easy to understand, but be sure to read the assignment as it mentions a simple bar graph will not suffice.
