Fig 1.
Spatial distribution change of electricity generation in Africa (2000–2019).
The spatial distribution pattern of electricity generation in Africa in 2000 and 2019 is on the left and right, respectively. The closer the color is to red, the greater the electricity generation. The closer the color is to yellow, the less electricity is generated.
Fig 2.
Spatial distribution change of economic scale in Africa (2000–2019).
The spatial distribution patterns of Africa’s economic scale in 2000 and 2019 are shown on the left and right sides, respectively. The closer the color is to red, the larger the economy. The color is about yellow, indicating a smaller economy.
