Global map of countries by total renewable internal freshwater resources (billion cubic meters) in 2020, according to World Bank [1]. This is the list of countries by total renewable water resources for the year 2020, based on the latest data available in January 2024, by World Bank and Food and Agriculture Organization (AQUASTAT data).

Withdrawals also include water from desalination plants in countries where they are a significant source. Withdrawals can exceed 100 percent of total renewable resources where extraction from nonrenewable aquifers or desalination plants is considerable or where there is significant water reuse.
Fresh water is a renewable resource, yet the world's supply of clean, fresh water is under increasing demand for human activities. [12] The world has an estimated 1.34 billion cubic kilometers of water, but 96.5% of it is salty. [13] Almost 70% of fresh water can be found in the ice caps of Antarctica and Greenland. Less than 1% of this water ...
This water supply is also renewable Perhaps most importantly, this is a renewable water source, which is why cities all over the West are now in various stages of building plants that can treat ...
Mexican presidential candidate Claudia Sheinbaum on Friday said that if elected, her administration would focus on water management and renewable energy as part of a plan to boost the country's ...
Saudi Arabia is the third most water stressed country in the world. [14] Saudi Arabia is one of the driest regions in the world, with no perennial rivers. Water is obtained from four distinct sources: [15] non-renewable groundwater from the deep fossil aquifers; desalinated water; surface water; renewable groundwater from shallow alluvial aquifers
According to the World Resources Institute (WRI), Iran ranks among the most water-stressed countries in the world. The country falls under the "extremely high" category on the Water Stress Index, where 80% to 100% of renewable water resources are withdrawn annually. This means Iran is utilizing nearly all of its available water supply for ...
Since water is about 800 times denser than air, even a slow flowing stream of water, or moderate sea swell, can yield considerable amounts of energy. Water can generate electricity with a conversion efficiency of about 90%, which is the highest rate in renewable energy. [87] There are many forms of water energy:
