Water for Energy – Energy for Water

“Energy production depends on water. It is used in power generation, primarily for cooling thermal power plants; in the extraction, transport and processing of fuels; and, increasingly, in irrigation to grow biomass feedstock crops. Energy is also vital to providing freshwater, needed to power systems that collect, transport, distribute and treat it. Each resource faces rising demands and constraints in many regions as a consequence of economic and population growth and climate change, which will amplify their vulnerability to one another”.
(IEA World Energy Outlook, Water for Energy)

Businesses are large water and energy users and at the same time offer solutions for resource efficiency. Understanding this nexus is of paramount interest to overcome resource constraints in the future and enhance business efficiency by providing co-optimised solutions.

Key Takeaways of the Event

  • Fundamentals to water-energy nexus are population growth and development. To satisfy these growths, more water, energy and land are required.
  • The challenge to global water is climate change and the trigger is the production of carbon dioxide. As climate change affects the hydrological cycle which can result in more floods and droughts. These in turn affect the water quality which can lead to diseases to humans. Hence, climate change can also be a human health issue.
  • While carbon dioxide production is high when coal is used as compared to alternative energy technologies, but fossil fuel uses less water in the energy production as compared to the alternative technologies.
  • In terms of global water use, agriculture is highest, and there is a fundamental difference between agricultural and industrial water use. Agriculture usually takes the water out of the system, while industrial water stays in the system and the wastewater can be treated and re-use.
  • Companies should include true cost of water in their businesses.
  • Energy is required for water treatment and for transportation of water, such as pumping.
  • There is a huge challenge in future energy demand, and this demand may not be easily satisfied using alternative energy technologies as these technologies usually require a lot of land and water.
  • Problems in the water-energy nexus can be solved through mitigation, such as integration of water and energy policies, or adaptation, such as use technologies to improve efficiencies.
