Journal of Public Economics. It also exists as groundwater in aquifers. As there is no protein or amino acid storage provision, amino acids must be present in the diet. Because science has an incomplete understanding of how food affects the human body, Pollan argues, nutritionism can be blamed for many of the health problems relating to diet in the Western World today. Galen thought that for a person to have gout , kidney stones , or arthritis was scandalous, which Gratzer likens to Samuel Butler's Erehwon where sickness is a crime.

But once you enjoy one of those sweet potatoes gilled on hot rocks I hope you don't mind, but I've shared your list on my blog for my readers as well. Please let me know if that's not okay and I will take down the list.

I really enjoy reading your blog since it's so helpful and insightful. Please continue to update! Can you also provide the kanji for the foods, so I can ask my friends on mixi about them? I hope, you didn't mention it. I don't know most of the dishes and just browsed your list. Otherwise my comment is useless ;. Thanks for the list. I already ate some of the dishes. I want to try all of them in the future ;D.

I like that you added some packaged products there, for those of us who aren't lucky enough to have easy access to fresh Japanese foods. I love my daily shot of Yakult. I counted around I was lucky enough to have lived and traveled in Japan in the past.

Some I had totally forgotten about. I used to love train travel. I've got 25 to learn about or don't recognize the names! I can't wait to hear about them! You sure have made me both nostalgic and very hungry indeed! I'm Japanese female who lives in Switzelrand. I searched about market in Helvetiaplatz Zürich. I wanted to know until what time does it go everytime.

And I found your blog. I'm glad about it! Since I 've moved in Switzerland. I'm trying to make Japanese Tofu, Natto,Nukazuke by myself. But it's difficult to find right things sometimes. So I made Nukazuke by bread and beer,I made tofu with soy beans and lemon and so on.

It's not bad so much. Anyway,I'm really happy that Japanese food are loved by a lot of people! I'm a Japanese female living in Switzerland too! I write in English so that more people around the world will get to like Japanese food: If anyone knows about other " Things You Must Eat" out there, be sure to leave us a comment! I haven't heard of most of these, but I do love tempura and Unadon.

I don't see one of my favorites--Futomaki. Almost everything I'd add to my list you already have! Such a complete list I can't imagine how long it must of taken to come up such variety. I'd add hijiki and also chikuwa with cucumbers and ume paste too.

Maybe when I can't figure out what to make for dinner, I'll just check out your list! Well, I haven't tried a whole lot of these, but my friend who went to Japan last summer with school and I spent almost an hour in an asian supermarket looking for Calpis so I could try it.

Actually, most of the stuff on here I've tried because of her! You've got such a great list here! I've only had about a quarter of these mostly fed to me by my obaachan in L.

Mmm, now I'm craving sweet potato tempura Thank you SO much for your detailed explanations on the first 40 of the Top Although I thought I knew something about some of them, your detailed explanations along with your links to recipes and the Kanji as well is truly helpful!

I am so delighted by your blogs and recipes. I'm looking forward to trying the "Wafuu Pasuta" recipes because of your links! As a broke university student Japanese curry especially cheap kind from Matsuya is one of my favorites! Found your site today, it's great, the bento counterpart as well! If you like foodie lists, you may want to add this one to listsofbests. Forgive me, but I only see 18 foods on the list of Japanese foods to try.

Will you guide me to where the rest of the 82 Japanese foods to try are? Well, this list was very good. But I thought it was a little specific. I'm living in Japan as a foreign exchange student, and I've been in Japan for a total of 5 months so far. I've tried a LOT of Japanese food. I am a gyoza enthusiast. I know this comes from China originally.. But that tastes so good when fresh and well cooked.. That is one of the few things that competes with Yakitori for a light beer and snack stop on the way home.

Thanks for the list, very interesting! Gyoza is one of my favorite foods ever, but I didn't think it was really Japanese and not drastically adapted the way Japanese yakisoba differs from Chinese lo mein so it's not on this list. Found this while looking up new Japanese foods to try -- my friends and I are Japanese culture enthusiasts and food lovers in particular and this list has helped me immensely.

Actually, your blog in general just rocks. One of our favorites is fried Gobo with chile. I make my own ume as we have Japanese plum trees. I dry Kaki in the fall also. I have never tried it, but it sounds and looks good. I want to try it. Do they have them at japanese resturaunts? Like sushiq, i also only see Did i get to the page the wrong way? Clicked the link from the recommended widget on the right side of the page.

I ate yakitori and ramen before I gave up meat, but there are two places in the Tokyo area that serve ramen made with fish. This is a fantastic list and resource. I'm very grateful for all the explanations. There were quite a few things I had tried but had no idea what they were called!

I'll be hunting a few of these foods out specially in the next couple of weeks. My husband and I recently moved back to Darwin, the capital of the Northern Territory from living in Cairns Queensland Australia for 4 years. The population is mostly Indonesian and Chinese here and there aren't so many Japanese or Korean tourists. I miss all of the Japanese outlets and little corner grocery stores could go to in Cairns so the limit of the Asian foods is now very limited.

Your list looks so good, so many delicious things to try, I'm glad I had a chance to try a lot of them while we were in Cairns. Thanks for printing this list. It brings back great memories of wonderful food experiences in Cairns, Australia.

WOW I'm very far behind on this list. I've been reading lots of manga, and there is always a mention of some kind of Japanese food in them mostly when they have school festivals. From all that manga, I've become mad on eating Japanese food! I've not tried very many things, but what I did try, I've loved. Now, is there anyone who lives in England and has a tokoyaki maker?? I've eaten a lot of the food on this list without knowing. Then again, there might be similarities between Japanese food and Taiwanese food.

It would have been helpful to have an English translation next to the food, then I would know what I was ordering in a Japanese Resturant. I know it is a bit complicated because there is fish based dashi nearly everywhere.. I completely agree with your top 5. I recently moved out on my own and I've gotten quite hooked on eating rice. Of course I could say it's because I'm Asian but seriously now that I've been washing and cooking rice properly I've become quite addicted.

And there really is nothing better than eating the tofu raw. That fresh light taste really is something. Actually combining your top 5 makes an amazingly divine meal even if it is rather simple. My top 5 as a 'binbou gakusei' poor student: Freshly cooked rice which has been washed and cooked properly 2. Chuukadon I get it as 'makanai' from work. Oh, you're killing me. I used to work in a Japanese restaurant long ago, and since then developed a great love for it.

Now I can't even get 90 percent of these things, and the 10 percent available are horribly expensive. For Chelsey, I too am a vegetarian living in Okinawa. So what if it cancels out half the list? What is baby ramen though? Definitely a good choice if you are at the Raumen Museum and want to sample all the bowls! Baby Ramen does not refer to a small portion of ramen. It's the brand name of an old fashioned snack. It looks like crumbled up instant ramen and comes in a little packet.

It's not really one of the highpoints of Japanese cuisine, but I threw it in there as a representative of dagashi, or traditional cheap 'penny candy' in Japan. What about Sanuki udon? Or is it on there and I just missed it? Sorry of that's the case. Great list though; I'm keen to try all of them if I can. This is a great list -- I wanted to print it out and eat list, it made me so hungry. Maybe I overlooked these, but some things seem to be missing:.

Okonomiyaki is at no. I also start the piece by saying I assume people have already tried sushi. I think the other things you mention are a bit too specific Although it's very regional, Sanuki udon should be on this list. I was very skeptical about how special people made this particular udon sound until I actually went to Takamatsu and tried it.

It really does stand head and shoulders above all other udon noodles, and is totally worth the trip to Shikoku -- even if you don't do anything other than eat. Curry udon might also be worth a mention as it is simply delicious. Jellied water in form of square noodles with soy sauce and mustard is definately one of the strangest things I've ever eaten, but it was quite tasty.

Unless I missed it I can't believe that Katsudon isn't on that list. To me that is one of the most quintessential Japanese foods. It was my first meal in Japan and I will never forget it.

I couldn't believe how many of these I don't know. I am a Japanese interpreter so I go to Japan all the time but I had no idea how many things I have never got to try. Thanks for the introduction. You forget my absolute favorite candy and I do not exaggerate, Kasugai gummy candy that comes in every flavor possible, like grape, muscat, lychee, orange, kiwi, mango, strawberry, apple, melon, peach etc.

It is to die for. Just the aroma of the bag itself will drive you nuts!! Everyone needs to just try their favorite flavor and you'll be hooked like me and many others.

Skip to main content. What Japanese foods would I recommend people try at least once? The older rice gets, the less desirable it is. This differs from some other rice cultures where aged rice e. See also How to cook Japanese rice. Tofu used to be sold by mobile street vendors, who would go around neighborhoods in the evening just before dinnertime tooting a loud horn. Housewives would rush to the vendor cart, bowls in hand, to buy fresh tofu. Photosynthesis , the process by which green plants and certain other organisms transform light energy into chemical energy.

During photosynthesis in green plants, light energy is captured and used to convert water , carbon dioxide , and minerals into oxygen and energy-rich organic compounds. It would be impossible to overestimate the importance of photosynthesis in the maintenance of life on Earth. If photosynthesis ceased, there would soon be little food or other organic matter on Earth.

The only organisms able to exist under such conditions would be the chemosynthetic bacteria , which can utilize the chemical energy of certain inorganic compounds and thus are not dependent on the conversion of light energy. Energy produced by photosynthesis carried out by plants millions of years ago is responsible for the fossil fuels i. There, protected from oxidation , these organic remains were slowly converted to fossil fuels.

These fuels not only provide much of the energy used in factories, homes, and transportation but also serve as the raw material for plastics and other synthetic products. Unfortunately, modern civilization is using up in a few centuries the excess of photosynthetic production accumulated over millions of years. Consequently, the carbon dioxide that has been removed from the air to make carbohydrates in photosynthesis over millions of years is being returned at an incredibly rapid rate.

Requirements for food, materials, and energy in a world where human population is rapidly growing have created a need to increase both the amount of photosynthesis and the efficiency of converting photosynthetic output into products useful to people.

One response to those needs—the so-called Green Revolution , begun in the midth century—achieved enormous improvements in agricultural yield through the use of chemical fertilizers , pest and plant- disease control, plant breeding , and mechanized tilling, harvesting, and crop processing.

This effort limited severe famines to a few areas of the world despite rapid population growth , but it did not eliminate widespread malnutrition. Moreover, beginning in the early s, the rate at which yields of major crops increased began to decline. This was especially true for rice in Asia.

Rising costs associated with sustaining high rates of agricultural production, which required ever-increasing inputs of fertilizers and pesticides and constant development of new plant varieties, also became problematic for farmers in many countries. A second agricultural revolution , based on plant genetic engineering , was forecast to lead to increases in plant productivity and thereby partially alleviate malnutrition.

However, such traits are inherently complex, and the process of making changes to crop plants through genetic engineering has turned out to be more complicated than anticipated.

In the future such genetic engineering may result in improvements in the process of photosynthesis, but by the first decades of the 21st century, it had yet to demonstrate that it could dramatically increase crop yields. Another intriguing area in the study of photosynthesis has been the discovery that certain animals are able to convert light energy into chemical energy. The emerald green sea slug Elysia chlorotica , for example, acquires genes and chloroplasts from Vaucheria litorea , an alga it consumes, giving it a limited ability to produce chlorophyll.

When enough chloroplasts are assimilated , the slug may forgo the ingestion of food. Sugar molecules are produced by the process of photosynthesis in plants and certain bacteria. These organisms lie at the base of the food chain, in that animals and other nonphotosynthesizing organisms depend on them for a constant supply….

The study of photosynthesis began in with observations made by the English clergyman and scientist Joseph Priestley. Priestley had burned a candle in a closed container until the air within the container could no longer support combustion.

He then placed a sprig of mint plant in the container and discovered that after several days the mint had produced some substance later recognized as oxygen that enabled the confined air to again support combustion. He also demonstrated that this process required the presence of the green tissues of the plant. Gas-exchange experiments in showed that the gain in weight of a plant grown in a carefully weighed pot resulted from the uptake of carbon, which came entirely from absorbed carbon dioxide, and water taken up by plant roots; the balance is oxygen, released back to the atmosphere.

Almost half a century passed before the concept of chemical energy had developed sufficiently to permit the discovery in that light energy from the sun is stored as chemical energy in products formed during photosynthesis.

In chemical terms, photosynthesis is a light-energized oxidation—reduction process. Oxidation refers to the removal of electrons from a molecule; reduction refers to the gain of electrons by a molecule. Most of the removed electrons and hydrogen ions ultimately are transferred to carbon dioxide CO 2 , which is reduced to organic products.

Tides are the cyclic rising and falling of local sea levels caused by the tidal forces of the Moon and the Sun acting on the oceans. Tides cause changes in the depth of the marine and estuarine water bodies and produce oscillating currents known as tidal streams. The changing tide produced at a given location is the result of the changing positions of the Moon and Sun relative to the Earth coupled with the effects of Earth rotation and the local bathymetry. The strip of seashore that is submerged at high tide and exposed at low tide, the intertidal zone , is an important ecological product of ocean tides.

From a biological standpoint, water has many distinct properties that are critical for the proliferation of life. It carries out this role by allowing organic compounds to react in ways that ultimately allow replication. All known forms of life depend on water. Water is vital both as a solvent in which many of the body's solutes dissolve and as an essential part of many metabolic processes within the body. Metabolism is the sum total of anabolism and catabolism.

In anabolism, water is removed from molecules through energy requiring enzymatic chemical reactions in order to grow larger molecules e. In catabolism, water is used to break bonds in order to generate smaller molecules e. Without water, these particular metabolic processes could not exist. Water is fundamental to photosynthesis and respiration.

Photosynthetic cells use the sun's energy to split off water's hydrogen from oxygen [ citation needed ]. Hydrogen is combined with CO 2 absorbed from air or water to form glucose and release oxygen [ citation needed ]. All living cells use such fuels and oxidize the hydrogen and carbon to capture the sun's energy and reform water and CO 2 in the process cellular respiration. Water is also central to acid-base neutrality and enzyme function.

Water is considered to be neutral, with a pH the negative log of the hydrogen ion concentration of 7. Acids have pH values less than 7 while bases have values greater than 7. Earth surface waters are filled with life. The earliest life forms appeared in water; nearly all fish live exclusively in water, and there are many types of marine mammals, such as dolphins and whales.

Some kinds of animals, such as amphibians , spend portions of their lives in water and portions on land.

Plants such as kelp and algae grow in the water and are the basis for some underwater ecosystems. Plankton is generally the foundation of the ocean food chain. Aquatic vertebrates must obtain oxygen to survive, and they do so in various ways.

Fish have gills instead of lungs , although some species of fish, such as the lungfish , have both. Marine mammals , such as dolphins, whales, otters , and seals need to surface periodically to breathe air. Some amphibians are able to absorb oxygen through their skin.

Invertebrates exhibit a wide range of modifications to survive in poorly oxygenated waters including breathing tubes see insect and mollusc siphons and gills Carcinus.

However as invertebrate life evolved in an aquatic habitat most have little or no specialisation for respiration in water. Civilization has historically flourished around rivers and major waterways; Mesopotamia , the so-called cradle of civilization, was situated between the major rivers Tigris and Euphrates ; the ancient society of the Egyptians depended entirely upon the Nile.

Rome was also founded on the banks of the Italian river Tiber. Islands with safe water ports, like Singapore, have flourished for the same reason. In places such as North Africa and the Middle East, where water is more scarce, access to clean drinking water was and is a major factor in human development.

Water fit for human consumption is called drinking water or potable water. Water that is not potable may be made potable by filtration or distillation , or by a range of other methods. Water that is not fit for drinking but is not harmful for humans when used for swimming or bathing is called by various names other than potable or drinking water, and is sometimes called safe water , or "safe for bathing".

Chlorine is a skin and mucous membrane irritant that is used to make water safe for bathing or drinking. Its use is highly technical and is usually monitored by government regulations typically 1 part per million ppm for drinking water, and 1—2 ppm of chlorine not yet reacted with impurities for bathing water. Water for bathing may be maintained in satisfactory microbiological condition using chemical disinfectants such as chlorine or ozone or by the use of ultraviolet light.

In the US, non-potable forms of wastewater generated by humans may be referred to as greywater , which is treatable and thus easily able to be made potable again, and blackwater , which generally contains sewage and other forms of waste which require further treatment in order to be made reusable.

These terms may have different meanings in other countries and cultures. This natural resource is becoming scarcer in certain places, and its availability is a major social and economic concern. Currently, about a billion people around the world routinely drink unhealthy water.

Most countries accepted the goal of halving by the number of people worldwide who do not have access to safe water and sanitation during the G8 Evian summit. Poor water quality and bad sanitation are deadly; some five million deaths a year are caused by polluted drinking water. The World Health Organization estimates that safe water could prevent 1. Water, however, is not a finite resource meaning the availability of water is limited , but rather re-circulated as potable water in precipitation [31] in quantities many orders of magnitude higher than human consumption.

Water-poor countries use importation of goods as the primary method of importing water to leave enough for local human consumption , [ further explanation needed ] since the manufacturing process [ clarification needed ] uses around 10 to times products' masses in water. The most important use of water in agriculture is for irrigation , which is a key component to produce enough food.

Fifty years ago, the common perception was that water was an infinite resource. At the time, there were fewer than half the current number of people on the planet. People were not as wealthy as today, consumed fewer calories and ate less meat, so less water was needed to produce their food. They required a third of the volume of water we presently take from rivers.

Today, the competition for the fixed amount of water resources is much more intense, giving rise to the concept of peak water. In future, even more water will be needed to produce food because the Earth's population is forecast to rise to 9 billion by An assessment of water management in agriculture was conducted in by the International Water Management Institute in Sri Lanka to see if the world had sufficient water to provide food for its growing population.

It found that a fifth of the world's people, more than 1. The report found that it would be possible to produce the food required in future, but that continuation of today's food production and environmental trends would lead to crises in many parts of the world.

To avoid a global water crisis, farmers will have to strive to increase productivity to meet growing demands for food, while industry and cities find ways to use water more efficiently. Water scarcity is also caused by production of cotton: While cotton accounts for 2. Significant environmental damage has been caused, such as disappearance of the Aral Sea. On 7 April , the gram was defined in France to be equal to "the absolute weight of a volume of pure water equal to a cube of one hundredth of a meter, and at the temperature of melting ice".

Work was therefore commissioned to determine precisely the mass of one liter of water. The Kelvin temperature scale of the SI system is based on the triple point of water, defined as exactly Natural water consists mainly of the isotopes hydrogen-1 and oxygen, but there is also a small quantity of heavier isotopes such as hydrogen-2 deuterium.

The amount of deuterium oxides or heavy water is very small, but it still affects the properties of water. Water from rivers and lakes tends to contain less deuterium than seawater. Most of this is ingested through foods or beverages other than drinking straight water. It is not clear how much water intake is needed by healthy people, though most specialists agree that approximately 2 liters 6 to 7 glasses of water daily is the minimum to maintain proper hydration.

For those who have healthy kidneys, it is rather difficult to drink too much water, but especially in warm humid weather and while exercising it is dangerous to drink too little. People can drink far more water than necessary while exercising, however, putting them at risk of water intoxication hyperhydration , which can be fatal.

Most of this quantity is contained in prepared foods. Specifically, pregnant and breastfeeding women need additional fluids to stay hydrated. The Institute of Medicine US recommends that, on average, men consume 3 liters 0. Water is excreted from the body in multiple forms; through urine and feces , through sweating , and by exhalation of water vapor in the breath.

With physical exertion and heat exposure, water loss will increase and daily fluid needs may increase as well. Humans require water with few impurities. Some solutes are acceptable and even desirable for taste enhancement and to provide needed electrolytes.

The single largest by volume freshwater resource suitable for drinking is Lake Baikal in Siberia. The propensity of water to form solutions and emulsions is useful in various washing processes. Washing is also an important component of several aspects of personal body hygiene.

Most of personal water use is due to showering , doing the laundry and dishwashing , reaching hundreds of liters per day in developed countries. The use of water for transportation of materials through rivers and canals as well as the international shipping lanes is an important part of the world economy.

Water is widely used in chemical reactions as a solvent or reactant and less commonly as a solute or catalyst. In inorganic reactions, water is a common solvent, dissolving many ionic compounds, as well as other polar compounds such as ammonia and compounds closely related to water. In organic reactions, it is not usually used as a reaction solvent, because it does not dissolve the reactants well and is amphoteric acidic and basic and nucleophilic. Nevertheless, these properties are sometimes desirable.

Also, acceleration of Diels-Alder reactions by water has been observed. Supercritical water has recently been a topic of research. Oxygen-saturated supercritical water combusts organic pollutants efficiently.

Water vapor is used for some processes in the chemical industry. An example is the production of acrylic acid from acrolein, propylene and propane. Water and steam are a common fluid used for heat exchange , due to its availability and high heat capacity , both for cooling and heating. Cool water may even be naturally available from a lake or the sea. It's especially effective to transport heat through vaporization and condensation of water because of its large latent heat of vaporization.

A disadvantage is that metals commonly found in industries such as steel and copper are oxidized faster by untreated water and steam. In almost all thermal power stations , water is used as the working fluid used in a closed loop between boiler, steam turbine and condenser , and the coolant used to exchange the waste heat to a water body or carry it away by evaporation in a cooling tower. In the United States, cooling power plants is the largest use of water. In the nuclear power industry, water can also be used as a neutron moderator.

In most nuclear reactors , water is both a coolant and a moderator. This provides something of a passive safety measure, as removing the water from the reactor also slows the nuclear reaction down. However other methods are favored for stopping a reaction and it is preferred to keep the nuclear core covered with water so as to ensure adequate cooling. Water has a high heat of vaporization and is relatively inert, which makes it a good fire extinguishing fluid.

The evaporation of water carries heat away from the fire. It is dangerous to use water on fires involving oils and organic solvents, because many organic materials float on water and the water tends to spread the burning liquid. Use of water in fire fighting should also take into account the hazards of a steam explosion , which may occur when water is used on very hot fires in confined spaces, and of a hydrogen explosion, when substances which react with water, such as certain metals or hot carbon such as coal, charcoal , or coke graphite, decompose the water, producing water gas.

The power of such explosions was seen in the Chernobyl disaster , although the water involved did not come from fire-fighting at that time but the reactor's own water cooling system. A steam explosion occurred when the extreme overheating of the core caused water to flash into steam. A hydrogen explosion may have occurred as a result of reaction between steam and hot zirconium. Humans use water for many recreational purposes, as well as for exercising and for sports.

Some of these include swimming, waterskiing , boating , surfing and diving. In addition, some sports, like ice hockey and ice skating , are played on ice. Lakesides, beaches and water parks are popular places for people to go to relax and enjoy recreation. Many find the sound and appearance of flowing water to be calming, and fountains and other water features are popular decorations.

Some keep fish and other life in aquariums or ponds for show, fun, and companionship. Humans also use water for snow sports i.

The water industry provides drinking water and wastewater services including sewage treatment to households and industry. Water supply facilities include water wells , cisterns for rainwater harvesting , water supply networks , and water purification facilities, water tanks , water towers , water pipes including old aqueducts.

Atmospheric water generators are in development. Drinking water is often collected at springs , extracted from artificial borings wells in the ground, or pumped from lakes and rivers.

Building more wells in adequate places is thus a possible way to produce more water, assuming the aquifers can supply an adequate flow.

Other water sources include rainwater collection. Water may require purification for human consumption. This may involve removal of undissolved substances, dissolved substances and harmful microbes. Popular methods are filtering with sand which only removes undissolved material, while chlorination and boiling kill harmful microbes. Distillation does all three functions. More advanced techniques exist, such as reverse osmosis.

Desalination of abundant seawater is a more expensive solution used in coastal arid climates. The distribution of drinking water is done through municipal water systems , tanker delivery or as bottled water.

Governments in many countries have programs to distribute water to the needy at no charge. Reducing usage by using drinking potable water only for human consumption is another option. In some cities such as Hong Kong, sea water is extensively used for flushing toilets citywide in order to conserve fresh water resources. Polluting water may be the biggest single misuse of water; to the extent that a pollutant limits other uses of the water, it becomes a waste of the resource, regardless of benefits to the polluter.

Like other types of pollution, this does not enter standard accounting of market costs, being conceived as externalities for which the market cannot account. Thus other people pay the price of water pollution, while the private firms' profits are not redistributed to the local population, victims of this pollution.

Pharmaceuticals consumed by humans often end up in the waterways and can have detrimental effects on aquatic life if they bioaccumulate and if they are not biodegradable.

Municipal and industrial wastewater are typically treated at wastewater treatment plants. Mitigation of polluted surface runoff is addressed through a variety of prevention and treatment techniques. See Surface runoff Mitigation and treatment. Many industrial processes rely on reactions using chemicals dissolved in water, suspension of solids in water slurries or using water to dissolve and extract substances, or to wash products or process equipment.

Processes such as mining , chemical pulping , pulp bleaching , paper manufacturing , textile production, dyeing, printing, and cooling of power plants use large amounts of water, requiring a dedicated water source, and often cause significant water pollution. Water is used in power generation. Hydroelectricity is electricity obtained from hydropower. Hydroelectric power comes from water driving a water turbine connected to a generator.

Hydroelectricity is a low-cost, non-polluting, renewable energy source.
