Water is used around the world for the production of electricity, but new research results show that there will not be enough water in the world to meet demand by 2040 if the energy and power situation does not improve before then.
Two new reports that focus on the global electricity water nexus have just been published. Three years of research show that by the year 2040 there will not be enough water in the world to quench the thirst of the world population and keep the current energy and power solutions going if we continue doing what we are doing today. It is a clash of competing necessities, between drinking water and energy demand. Behind the research is a group of researchers from Aarhus University in Denmark, Vermont Law School and CNA Corporation in the US.
In most countries, electricity is the biggest source of water consumption because the power plants need cooling cycles in order to function. The only energy systems that do not require cooling cycles are wind and solar systems, and therefore one of the primary recommendations issued by these researchers is to replace old power systems with more sustainable wind and solar systems.
The research has also yielded the surprising finding that most power systems do not even register how much water is being used to keep the systems going.
By 2020 the water issue affects 30-40% of the world
“It’s a huge problem that the electricity sector do not even realise how much water they actually consume. And together with the fact that we do not have unlimited water resources, it could lead to a serious crisis if nobody acts on it soon”, says Professor Benjamin Sovacool from Aarhus University.
