This is according to two recently published reports that focus on the relationship between water and the global production capacity of electricity
[Translation by Dr. Nachmani Moshe]
Water is used all over the world to produce electricity, but the results of a new study show that in 2040 there will not be a sufficient amount of water to meet global demand, all if the energy situation and sources of electricity are not improved by then.
Two reports focusing on the relationship between water and global electricity generation capacity have just been published. The first among them is a three-year study indicating that by the year 2040 there will not be a sufficient amount of water in the world to quench the thirst of the entire world population while preserving the current solutions in the fields of energy and electricity production, if we continue to behave as we do today. This is essentially a conflict between two competing needs - between drinking water and the demand for energy. The study was conducted by a group of researchers from Aarhus University in Denmark and the CNA Corporation in the USA.
In most countries, electricity production is the main source of water consumption, this is due to the fact that power plants require water cooling systems in order to function. The only energy systems that do not require water cooling systems are systems powered by the wind or solar systems, and therefore, one of the recommendations that came out of these studies is to convert old systems into more advanced and sustainable systems powered by the wind or with the help of solar energy . The study also indicated that, surprisingly, most electricity generation systems do not record the amount of water used to operate these systems at all.
"It is a big problem that the power generation industry does not even know how much water it consumes every year. And together with the fact that we do not have an unlimited amount of water sources, the situation could lead to a serious crisis if no one takes care of it now," says Professor Benjamin Sovacool from Aarhus University.
Combining the results of the new study together with the predictions regarding water shortages and the rate of population growth in the world, indicates that by the year 2020, many countries in the world will not have access to clean drinking water. In fact, the results predict that by the year 2020 the issue of water shortage will affect 40-30% of the world, and the researchers add and say that climate changes may worsen the situation even more. "These predictions mean that the world will have to decide how to use our water in the future. Would we want to use them to continue operating power plants or as drinking water? We don't have enough to meet both of these requirements," says the lead researcher.
So what are the possible solutions?
In the reports, the researchers highlight six general recommendations that the decision-makers must implement in order to prevent this trend and deal with the rapidly approaching global crisis:
1. Improving energy efficiency
2. More vigorous research regarding the development of alternative cooling systems
3. Documenting and registering the quantities of water used in power plants
4. Substantial investments in wind energy
5. Substantial investments in solar energy
6. Neglect of all production facilities that use fossil fuels in all areas where there is a shortage of water.
The team of scientists conducted their research focusing on four separate test cases in France, the US, China and India. Instead of examining the situation at the national level, the team narrowed down and focused on specific services and energy suppliers. The first step was to identify the current energy needs and then the researchers ran projections going forward until 2040, and most of the results were very surprising. In all four case studies, the predictions indicated that it would not be possible to continue producing electricity in the current way and still meet the demands for water in 2040. Free, since the issue is not related to the price but to the availability of water. If we do not act today, we are expected to have a serious crisis in this area," says the researcher.

The recommendation of the experts is Bamba and some experience in repetitions so that we are at the same height of the table

In which hospital are you hospitalized in Shalvata or Abarbanal? we care about you What to get you Bamba or Doritos?
Miracles, I was once a "rally" too, but after the rehearsals you discover both parallel universes and (even though it's hard to understand) intelligences that are erased in time. And listen, this can also be a rally. Sincerely

certainly. He is ignored. All in all he is just looking for attention. If he doesn't accept it here, he will return to Amma'la and not bully her, and not us.
It is that without examples of foresight we are still with feet on the ground

To call blowing water a troll is a compliment. Just a microbe that accidentally grew to the size of a human being. Maybe you know how to return it to its natural dimensions - nano microscopic.
Dear Mr. Nissim, I know it sounds like that, unfortunately, but if you had experience in rehearsals, you wouldn't be able to keep your mouth shut either, and what's more, I don't want it to get blown out of proportion, something I ran away from in a parallel world. With great respect
Do us all a favor and don't pay attention to blowing water. He's just a troll.
Sometimes it would cause me problems because they would transfer money from a supplier to the supplier according to my balance and it would jam their computers. Sincerely
Honorable Mr. Socrates, I once even had a balance of a billion on a credit card, we will see you explain to the callers what it is and how it appears that sometimes it is transparent from returns. In honor truly in honor water blows
Water blowing
It's new that you know what a credit card is.
The honorable Dak Mokh and the last one who wrote in my honorable name, I hereby charge you four new shekels, the invoice may be sent and if you block the card you will wait.
Water blowing: I see that you successfully underwent the lobotomy operation..
you see I can write about other topics besides time returns.

I ask the same question. As far as I know, the water used by hydroelectric plants which is fresh water, is returned for drinking purposes. And on the other hand - they build power plants near the sea to use sea water for cooling.
Parasitizing water costs as far as I know around four shekels per cube
Is it safe to use potable water to generate electricity?

Your words require an explanation. As you do in the holy place, you make a Jerusalem mix out of everything you read. Please write a neat article including places. You rely on populist slogans and half-truths. If you don't want to get a failing grade at the end of the semester, do as my mitzvah, a mitzvah of a loving father and you will be well.
As far as I understand..in two years Israel can switch to 100% production of water from desalinated water. Also, since we are world leaders in this technology, the costs of production are relatively small and we have also solved quite serious problems such as the introduction of minerals into the same water.
Since Israel is located on the coast of the Mediterranean Sea, I see no real reason for us to have a shortage of them.
They once also said that in the future (today) there will not be enough food for everyone. If Islam with the help of the global left does not take over the world there will be water for everyone, if so there will still be enough water because humanity will decrease by billions. (DEPOPULATION AGENDA) of the global left.
