Ethiopia probably have cheap electricity as well because it's situated in the
Nile basin. I did some research, and they have quite a number of hydroelectric power plants -
https://www.gem.wiki/Category:Hydroelectric_power_plants_in_Ethiopiain the article, they say
“100% of the data center’s electricity comes from renewable energy sources, specifically from the Grand Ethiopian Renaissance Dam, the largest hydropower project in Africa, with a capacity of 5.15 GW,”
That dam is not 100% built yet so it's only going to yield a fraction of the electricity that the article cited.
Let's hope they're not going to ursup all the residential electricity though, my neighborhood is farthest from the nearest power grid so we get more frequent outages.
