Albania: 90% Hydropower, $12150 GDP/person

Bhutan: 99% Hydropower, $ 4700 GDP/person

Nepal: 23% Imported $ 1381 GDP/person

            rest Hydropower  (2/3 of energy: firewood etc.)

Paraguay: 100% Hydropower, $ 7990 GDP/person

Iceland: 99% Hydry/Geo, $90000 GDP/person

Ethiopia: 88% Hydropower, $ 1350 GDP/person

DR Kongo: 98% Hydropower, $ 760 GDP/person , 13% of country has electricity

Not sure how this is applicable (and in many cases: desirable) for countries that do not have significant hydropower potential or maybe want a GDP greater than $760 per person per year.
