There are reasons why hydropower is the largest renewable resource:
First: the earth is 71% water and 29% land. In theory, water is the largest resource, but among them, sea water accounts for 96.5%; while fresh water resources on earth are less than 3%; the ocean has become the largest source of water resources;
Second: electrical energy is theoretically infinite, because it can use wind energy. , tidal power, thermal power and hydropower, electric power has a huge advantage in that there is virtually no pollution. If hydropower is used under ideal circumstances, it is possible to generate endless electrical energy, therefore hydropower It has the title of the largest renewable energy. resource
