Canada, China, Brazil, the United States, and Russia have the largest energy production from hydroelectric power and they account for over 50 percent of the total capacity in the world.
Hong Kong currently does not have hydroelectric power generation and is incapable of large-scale hydroelectric generation because their rivers do not have sufficient flow and height [30]. However, there are some locations that are being looked at for small-scale hydroelectric power. Predicting that these are installed in the future but nothing that is highly successful, I give hydroelectric power a maximum of 1 kWh per day per person.
