Worldwide water shortage by 2040

Water is used around the world for electricity generation, but new research results show that there will not be enough water in the world to meet demand in 2040 if the power and electricity situation does not improve before then. .

Two new reports have just been released that focus on the global link to electricity and water. Three years of research show that by 2040 there will not be enough water in the world to quench the thirst of the world’s population and keep current energy and energy solutions running if we continue to do what we are doing today. It is a clash of competing needs, between drinking water and energy demand. Behind the research is a group of researchers from Aarhus University in Denmark, Vermont Law School, and the CNA Corporation in the United States.

In most countries, electricity is the main source of water consumption because power plants need cooling cycles to function. The only energy systems that do not require cooling cycles are wind and solar systems, so one of the main recommendations issued by these researchers is to replace old electrical systems with more sustainable wind and solar systems.

The research also produced the surprising discovery that most power systems don’t even record how much water is used to power the systems.

By 2020, the water problem will affect 30-40% of the world

“It’s a big problem that the electricity sector doesn’t even realize how much water it actually consumes. And coupled with the fact that we don’t have unlimited water resources, it could lead to a major crisis if no one intervenes soon,” says Professor Benjamin Sovacool of the University. of Aarhus.

Combining the new research findings with water scarcity and world population projections, he shows that by 2020, many areas of the world will no longer have access to clean water. In fact, the results predict that by 2020 around 30-40% of the world will be short of water, and according to the researchers, climate change may make the situation worse.

“This means that we will have to decide where to spend our water in the future. Do we want to spend it to keep power plants running or as drinking water? We don’t have enough water to do both,” says Professor Benjamin Sovacool.

How to solve the problem?

In the reports, the researchers point out six general recommendations that decision makers must follow to halt this development and manage the crisis around the world:

Improve energy efficiency
Best Research on Alternative Cooling Cycles
Record the amount of water used by power plants
Massive investments in wind energy
Massive investments in solar energy
Abandon fossil fuel facilities in all water stressed places (which means half the planet)
