OPINION: Renewable energy-based desalination could resolve India’s perennial water woes. The ever-increasing demand for potable water is exerting tremendous stress on our existing consumable water resources. Water covers a little over 70 per cent of the earths surface, and by this we erroneously presume that there is adequate potable water. Realistically, only 3 per cent of this water is potable. According to a study in Science Advances, some African and Asian countries face severe water scarcity for almost the entire year. The same study also reveals that India suffers from water scarcity for over seven months a year. (LINK). HIWI042018-06-22T08:17:33+02:00
