**Summary:**
In response to a question regarding the use of wind turbines for generating water from air moisture and separating oxygen, the Ministry of Earth Sciences addressed the Lok Sabha on July 23, 2025. The Ministry acknowledged that using electricity from wind turbines to generate water through condensation is a nascent technology and that suitable proposals in this area would be considered under the Renewable Energy Research and Technology Development (RERTD) Program of the Ministry of New and Renewable Energy. The Ministry also noted that the National Institute of Ocean Technology, under the Ministry of Earth Sciences, has developed an experimental air conditioner-cum-water generator system capable of producing 100 liters of fresh water per day while functioning as a standard air conditioner. This system operates by condensing water vapor from the air during the cooling process and can be powered by electricity generated from wind turbines. The Minister of State Independent Charge for Ministry of Science and Technology and Earth Sciences, Dr. Jitendra Singh, provided the response.

UNSTARRED QUESTION NO. 667
TO BE ANSWERED ON WEDNESDAY, 23RD JULY, 2025
WIND TURBINES IN GENERATING WATER
667. Ms MAHUA MOITRA:
Will the Minister of EARTH SCIENCES be pleased to state:
(a) whether the Government is considering to use the Wind Turbines in generating water
from moisture in air for coastal areas and separating oxygen from air for larger
societal benefit; and
(b) if so, the details thereof and if not, the reasons therefor?
ANSWER
THE MINISTER OF STATE (INDEPENDENT CHARGE) FOR
MINISTRY OF SCIENCE AND TECHNOLOGY
AND EARTH SCIENCES
(DR. JITENDRA SINGH)
(a) & (b) The Electricity produced from Wind Turbines can be utilized to generate water from
moisture in air through condensation process. However, this technology is still at a
nascent R&D stage. Suitable proposals in this area are considered under the
Renewable Energy Research and Technology Development (RE-RTD) Program of
the Ministry of New and Renewable Energy. National Institute of Ocean Technology
under Ministry of Earth Sciences has developed on experimental basis, an Air
conditioner cum Water generator system capable of generating 100 litres of fresh
water per day, while serving as a normal air conditioner. The system works on the
principle that in the process of cooling air, water vapour present in the air is also
condensed to produce water. The system can be powered using electricity produced
from wind turbines.
