What the numbers mean
Hydropower can dominate a country's electricity generation without dominating its entire energy system. Transport and direct fuel use sit outside this denominator. Rainfall and reservoir conditions can also change hydro output between years. A high share therefore describes one year's electricity mix, not a guarantee about every season.
Where the top ten ends
The tenth entry is Kyrgyzstan at 88.78. This is a cutoff within the published comparison, not evidence that countries outside the table have no activity. The date and coverage are part of the answer: updating the source or changing the eligible territories can change who appears.
