Elon Musk is proposing solutions to the global water crisis: Opinions and Reactions
Elon Musk, known for his futuristic vision and technological innovations in areas such as electric vehicles and space exploration, recently brought attention to the global water crisis by proposing solutions at the World Water Forum in Bali, Indonesia.
In his speech, Musk emphasized that the water crisis is indeed a solvable challenge and highlighted the potential of desalination as part of the solution. While desalination itself is not an innovative solution, Musk aims to emphasize the possibility of using solar energy to reduce the costs of this technology and make it more accessible on a large scale. Referring to the decreasing costs in desalination, Musk stated that this technology can essentially turn any region of the world green, including the entire planet. He also highlighted the underestimated importance of solar energy in powering the desalination process, indicating that integrating renewable energy sources can unlock water abundance.
However, reactions to Musk’s proposals have been mixed. Some have welcomed his optimism and focus on technological innovation as a way to address the water crisis, while others have expressed concerns about the feasibility and social and ecological implications of large-scale desalination.
One commentator noted that building desalination plants requires significant upfront capital, making them a major financial investment for governments or private companies. Additionally, the ongoing costs of energy, maintenance, and chemicals make desalination an expensive option for water supply compared to alternatives such as conservation or wastewater recycling. Furthermore, there are concerns about the environmental impact, including effects on marine ecosystems and intensive energy usage.
Moreover, in the context of discussions about water crisis solutions, it is essential not to overlook the issue of water losses, known as Non-Revenue Water (NRW). These losses, resulting from leaks, unauthorized consumption, or administrative errors, are a significant problem in many water supply systems worldwide. Reducing water losses can contribute to more efficient use of existing resources and increase water availability for end consumers.
Another commentator emphasized the importance of a holistic approach to addressing the water crisis, highlighting the need not to underestimate the complexity of the issue and its interconnections with other aspects of sustainable development.
While Musk has been praised for his approach, some have considered his proposals to be too technocentric and may underestimate the importance of conservation, recycling, and efficient water use practices.
Elon Musk’s speech at the World Water Forum has sparked a broad debate on the optimal ways to address the global water crisis. While technological innovations are appreciated, there is a call for a holistic approach that considers the social, economic, and ecological aspects of water resource management to ensure a sustainable and equitable future for all inhabitants of the planet.
People often think the water crisis is unsolvable, but in fact it is very solvable.”

He referenced desalination, with the cost having „dropped so much”…you can basically „turn any part of the world green, including the entire world”.
It comes down to energy, with solar energy currently „underestimated”.
I visited the Ghantoot site in Abu Dhabi back in 2017 where multiple technology pilot projects were driving to get the energy down (https://shorturl.at/sgR1L).
At the time, 4 kWh/m3 was the target, with some companies reporting 1.3 kWh/m3 to 1.4 kWh/m3 (on small scale systems).
Do you agree/disagree with Elon? He’s suggested renewable powered desalination could unlock water abundance. Thoughts below ????
The water problem is completely solveable Elon is correct there and desalination is part of the solution but not in lieu of properly managed assets and low/no hashtagNRW ????
My good friend and peer stuart hamilton would agree there. I don’t agree that it should be an ambition to turn the world green. That’s just ill thought through rhetoric that is counter-biodiversity’. Views are my own of course. As for aliens, please.
Elon seems to totally forget about a ‘few’ things… Such as
– Building desalination plants requires substantial upfront capital, making it a significant financial commitment for governments or private companies.
– The ongoing costs of energy, maintenance, and chemicals make desalination an expensive option for water supply compared to alternatives like conservation or wastewater recycling.
– Desalination plants often use open ocean intakes, which trap and kill marine organisms. The discharge of highly concentrated brine back into the ocean can create dead zones where marine life cannot survive (and is already happening in many places)
– Chemicals used in the desalination process, such as anti-scalants and cleaning agents, can harm marine ecosystems if not properly managed.
– While integrating renewable energy sources can mitigate some of these impacts, the transition is still in progress and often not fully implemented.
– The brine discharge increases the salinity of local marine environments, which can negatively affect marine biodiversity.
– Desalination can introduce microplastics and other contaminants into the environment if not properly managed.It is far more efficient to recycle & reuse water as many ways as possible.
