Green Energy for Water Management
What is it?
The devastating floods of 2022 left extensive consequences, a prominent one being water contamination in the flood-affected areas. While installing desalination plants to fulfill the need for safe drinking water is underway, these systems have high energy consumption and negative environmental impacts which need to be minimized. To address this challenge, the adoption of green energy solutions for water management may prove crucial. Green energy refers to renewable energy sources that have minimal impact on the environment. Solar energy, in particular, holds great potential for water management, offering sustainable processes for capturing and filtering water.
Solar energy offers various applications for sustainable water management. Solar-powered water pumps can extract water from contaminated sources, providing clean water for communities. Solar-powered desalination systems are effective in converting seawater into freshwater, addressing water scarcity issues. Additionally, solar-powered filtration units and purification systems can eliminate contaminants, ensuring the provision of safe drinking water. These applications showcase the potential of solar energy in water management and its role in mitigating the effects of water contamination in flood-affected or otherwise vulnerable regions.
Have other countries used Green Energy?
Several projects in developing countries have successfully implemented green energy solutions for water management, resulting in significant benefits:
- India: The Swajal Scheme provides solar-powered water purification systems in the form of solar huts operating in New Delhi, Haryana, and Uttar Pradesh. At present, they provide over 10,000 families and 50,000 people living in slums and rural villages with access to clean water. Studies have shown immediate health improvements and productivity amongst the affected communities as a result.
- Bangladesh: The Department of Public Health Engineering (DPHE) undertook a project titled “Providing Safe Drinking Water Through Installing Environment-friendly Solar Desalination Systems”, successfully installing 1,140 solar desalination units across 16 coastal districts.
Has Pakistan used it?
Pakistan’s government in Punjab has implemented an 80% subsidy program to support farmers by providing them with solar panel systems. These systems aim to enhance agricultural production, particularly in areas such as irrigation. While green energy is already being utilized in several crucial sectors across the country, its application in water management is scarce. However, the government of Balochistan and UNDP are working to bring clean drinking water to remote villages in Noshki through solar plants. Alongside this, private initiatives such as Bondh E Shams’ OASIS boxes are working to provide clean drinking water in rural villages in Pakistan.
In order to maximize the potential of solar energy in our country, the government should incentivize the adoption of solar energy systems for water management through greater subsidies, tax breaks, and financial assistance. This approach will encourage individuals, communities, and industries to invest in solar-powered water pumps, filtration units, and purification systems. The implementation of green energy solutions for water management in Pakistan holds tremendous future potential. With increasing technological advancements and declining costs of solar energy systems, the scalability and affordability of these solutions are expected to improve. By expanding the use of solar-powered systems, Pakistan can enhance water security, mitigate the impact of floods, and improve public health in flood-affected regions.
