Improved desalination efficiency is a primary factor contributing to this reduction. Energy consumption remains a significant cost component, accounting for up to half the total cost of the desalination process. [105] Desalination can substantially increase energy intensity, particularly for regions with limited energy resources.
Sustainable Development Goal 6 (SDG 6 or Global Goal 6) declares the importance of achieving "clean water and sanitation for all". It is one of the 17 Sustainable Development Goals established by the United Nations General Assembly to succeed the former Millennium Development Goals (MDGs). According to the United Nations, the overall goal is to ...
Sustainable use of groundwater is essential in water conservation. A fundamental component to water conservation strategy is communication and education outreach of different water programs. [ 11 ] Developing communication that educates science to land managers, policy makers, farmers, and the general public is another important strategy ...
Desalination is a process that removes mineral components from saline water. More generally, desalination is the removal of salts and minerals from a substance. [15] One example is soil desalination. This is important for agriculture. It is possible to desalinate saltwater, especially sea water, to produce water for human consumption or irrigation.
Although desalination also comes with environmental concerns, such as costs and resources, researchers are working closely to determine more sustainable practices, such as creating more productive water plants that can deal with larger water supplies in areas where these plans weren't always available.

The first modern large-scale desalination plant was the Perth Seawater Desalination Plant, completed in November 2006 and over 30 plants are currently operating across the country. Many plants are utilizing nearby wind or wave farms to use renewable energy and reduce operating costs, and solar powered desalination units are used for remote ...
Geothermal desalination refers to the process of using geothermal energy to power the process of converting salt water to fresh water. The process is considered economically efficient, and while overall environmental impact is uncertain, it has potential to be more environmentally friendly compared to conventional desalination options.

A microbial desalination cell (MDC) is a biological electrochemical system that implements the use of electro-active bacteria to power desalination of water in situ, resourcing the natural anode and cathode gradient of the electro-active bacteria and thus creating an internal supercapacitor.
