Unique observation – Without china excluded from the map, the rest of the map all look like 1 color. This signifies that china is estimated to make a lot more energy than anyone else in 2018

Question
Is the color scheme easy to understand or should I change try something else?

The color scheme is fine as is. You may benefit from experimenting with other color schemes in order to find one you think fits it best.
