1. Hydroelectricity is a renewable energy source.
Hydroelectricity uses the energy of running water, without reducing its quantity, to produce electricity. Therefore, all hydroelectric developments, of small or large size, whether run of the river or of accumulated storage, fit the concept of renewable energy.
2. Hydroelectricity makes it feasible to utilize other renewable sources.
Hydroelectric power plants with accumulation reservoirs offer incomparable operational flexibility, since they can immediately respond to fluctuations in the demand for electricity. The flexibility and storage capacity of hydroelectric power plants make them more efficient and economical in supporting the use of intermittent sources of renewable energy, such as solar energy or Aeolian energy.
3. Hydroelectricity promotes guaranteed energy and price stability.
River water is a domes resource which, contrary to fuel or natural gas, is not subject to market fluctuations. In addition to this, it is the only large renewable source of electricity and its cost-benefit ratio, efficiency, flexibility and reliability assist in optimizing the use of thermal power plants.
4. Hydroelectricity contributes to the storage of drinking water.
Hydroelectric power plant reservoirs collect rainwater, which can then be used for consumption or for irrigation. In storing water, they protect the water tables against depletion and reduce our vulnerability to floods and droughts.
5. Hydroelectricity increases the stability and reliability of electricity systems.
The operation of electricity systems depends on rapid and flexible generation sources to meet peak demands, maintain the system voltage levels, and quickly re-establish supply after a blackout. Energy generated by hydroelectric installations can be injected into the electricity system faster than that of any other energy source. The capacity of hydroelectric systems to reach maximum production from zero in a rapid and foreseeable manner makes them exceptionally appropriate for addressing alterations in the consumption and providing ancillary services to the electricity system, thus maintaining the balance between the electricity supply and demand.
6. Hydroelectricity helps fight climate changes.
The hydroelectric life cycle produces very small amounts of greenhouse gases (GHG). In emitting less GHG than power plants driven by gas, coal or oil, hydroelectricity can help retard global warming. Although only 33% of the available hydroelectric potential has been developed, today hydroelectricity prevents the emission of GHG corresponding to the burning of 4.4 million barrels of petroleum per day worldwide.
7. Hydroelectricity improves the air we breathe.
Hydroelectric power plants don't release pollutants into the air. They very frequently substitute the generation from fossil fuels, thus reducing acid rain and smog. In addition to this, hydroelectric developments don't generate toxic by-products.
8. Hydroelectricity offers a significant contribution to development.
Hydroelectric installations bring electricity, highways, industry and commerce to communities, thus developing the economy, expanding access to health and education, and improving the quality of life. Hydroelectricity is a technology that has been known and proven for more than a century. Its impacts are well understood and manageable through measures for mitigating and compensating the damages. It offers a vast potential and is available where development is most necessary.
9. Hydroelectricity means clean and cheap energy for today and for tomorrow.
With an average lifetime of 50 to 100 years, hydroelectric developments are long-term investments that can benefit various generations. They can be easily upgraded to incorporate more recent technologies and have very low operating and maintenance costs.
10. Hydroelectricity is a fundamental instrument for sustainable development.
Hydroelectric enterprises that are developed and operated in a manner that is economically viable, environmentally sensible and socially responsible represent the best concept of sustainable development. That means, "development that today addresses people's needs without compromising the capacity of future generations for addressing their own needs" (World Commission on the Environment and Development, 1987).
The best way to start saving on your electricity costs is to get smart with how you use electricity. Make these 21 no-cost changes in your home and you could save $500 or more a year, depending on a number of factors including the size of your home.
Now's the time to also join Team Power Smart and start a Reduction Challenge. If you can deliver on most of the 21 changes below, you could reduce your electricity use by 10% over the year and earn a $50 reward.
well, I am a very foody person and there are a lot of food I . It is quite difficult to think of one. I would to talk about a popular menu in my country which is one of my favourite food also. It is steamed/plain rice and shahi paneer. I belong to Punjabi family so that I love spicy and shahi foods.
I will talk about how I cook my shahi paneer at home. A small amount of oil is placed in a heated pan. Then, I put some finely chopped garlic until it turns golden brown. Add onions.when it turns golden brown then I blend it with help of a blender. a mixture of this I put some chopped tomatoes and heat it again.after that I add some cashews and fresh cream which provide creamy and rich gravy of our shahi paneer.apart from that then add paneer cubes, all spices and cook it till 20 minutes. Then it is done and ready to be served. You may also add some curd in place of fresh cream.
I it because it is easy to prepare and it is very delicious. gravy of this also feel me rich and when I taste it just melted our mouth.
This recipe is common in my country and I eat it about a twice week. I it because it does not require much effort to prepare and it is also not expensive.
Do you feel okay? Good luck to you.
Hope you get good grades.
Cause:
The Viruses:
One reason why there is no cure for the common cold is that more than 200 different viruses can cause cold symptoms.
Some, such as rhinoviruses, seldom produce serious illnesses.
Others, such as respiratory syncytial virus (RSV), produce mild infections in adults but can lead to severe lower respiratory tract infections in young children.
ADVERTISEMENTS:
Rhinoviruses (from the Greek rhin, meaning “nose”) cause an estimated 30 to 50 percent of all colds. Scientists have identified more than 100 distinct rhinovirus types. Rhinoviruses grow best at temperatures of about 9IT, (the temperature inside the human nose). Scientists think coronaviruses cause about 10 to 15 percent of all adult colds. They bring on colds primarily in the winter and early spring. Although many coronaviruses infect animals, only five infect humans, causing respiratory tract illness.
Adult cold symptoms also are caused by viruses that are responsible for other, more severe illnesses. These viruses are: adenoviruses, coxsackieviruses, echoviruses. orthomyxoviruses (including influenza A and B viruses, which cause flu), paramyxoviruses (including several parainfluenza viruses), RSV, and enteroviruses. Researchers still haven’t identified the causes of 20 to 30 percent of adult colds, presumed to be viral.
The cold season:
Seasonal changes in relative humidity also may affect the occurrence of colds. The most common cold-causing viruses survive better when humidity is low Cold weather also may make the inside lining of your nose drier and more vulnerable to viral infection.
Other factors:
Although a connection exists between the number of cases of the common cold and the fall and winter seasons, there is no experimental evidence that exposure to cold temperatures increases the chances of getting a cold. On the other hand, several research studies show that people who exercise regularly have a significantly reduced number of respiratory tract infections, such as the common cold, compared with those who don’t exercise. Research also suggests that allergic diseases that affect the nose or throat and psychological stress may increase your chances of getting infected by cold viruses.
Common Cold:
Symptoms:
Symptoms of the common cold usually begin 2 to 3 days after infection and often include:
ADVERTISEMENTS:
1. Sore throat
2. Mucus buildup in the nose
3. Difficulty breathing through nose
4. Swelling of sinuses
5. Sneezing
6. Cough
7. Headache
8. Tiredness
ADVERTISEMENTS:
Although fever is uncommon in adults, it is often found in children with colds and can climb to 102°F in infants and young children. Cold symptoms can last front 2 to 14 days. High fever, significantly swollen glands, severe sinus pain, and a cough that produces mucus may be signs of complication or more serious illness.
Treatment:
There is no cure for the common cold, but you can get relief from your cold symptoms by
1. Resting in bed
2. Drinking plenty of fluids
3. Gargling with warm salt water or using throat sprays, or lozenges for a scratchy or sort’ throat
4. Using a decongestant or saline nasal spray to help relieve nasal symptoms
5. Using petroleum jelly to soothe a raw nose
6. Taking aspirin or acetaminophen—Tylenol, for example—for headache or fever Colds occasionally can lead to bacterial infections of your middle ear or sinuses, requiring treatment with antibios. However, antibios should not be used to treat a cold.
Prevention:
There are several ways you can keep yourself away from getting a cold of infecting others:
1. Because cold viruses can easily enter into your eyes and nose through hands, wash hands often and keep the hands away from those areas of your body.
2. 11 possible, avoid being close to people who have colds or If you have a cold, avoid being close to people.
3. When you sneeze or cough, cover your nose of mouth arid sneeze or cough into your elbow rather than your hand.
Hand washing:
Hand washing with soap and water is the simplest and one of the most effective ways to keep from getting colds or giving them to others.
Disinfecting:
Rhinoviruses can live up to 3 hours on your skin or on objects. Cleaning these environmental surfaces in your home or place of work with a virus-killing disinfectant might help prevent the spread of infection.
Vaccine:
Because so many different viruses can cause the common cold, the outlook for developing a vaccine that will prevent spreading of all of them is quite a challenge.
Alternative Medicines:
Echinacea:
Echinacea is a dietary herbal supplement that some people use to treat their colds.
Vitamin C:
Many people are convinced that taking large quantities of vitamin C will prevent colds or relieve symptoms.
Honey:
Some people use honey to treat coughs and to soothe a sore throat.
Zinc:
Zinc lozenges and lollipops are available over the counter as a remedy for the common cold. In 2009, the Food and Drug Administration warned consumers to stop using intranasal (in the nose) zinc products because some people reported a loss of smell after using these products.

Generally, people in Malaysia drink water to meet their thirst and sometimes they take some soft drinks as well Kickapoo, Fruit Tree, Ice Mountain, and Freedom Cola etc. But I prefer to have chocolate milk as my soft drink.
People drink soft drinks most of the cases when they are out of their home and need to meet their thirst for water. But interestingly, instead of water, they prefer the soft drink. But I do not take such soft drinks as those are made with different chemicals which are highly detrimental to the human health. Most of the soft drinks are filled with gases and some chemicals which are mostly used to prepare insecides and other chemical substances. It has been found that the elements used in the soft drinks and the substances used for toilet cleaner are almost the same. Once I used to take the soft drinks when I went for outing with my buddies but as I came to know about the harmful impacts of the soft drinks, I started avoiding them. Instead, I have made chocolate milk as my personalised soft drink. It is healthy and also keeps me strong.
Making chocolate milk at home is a bit troublesome and thus I have to buy it from stores. There are different brands of chocolate milk which are available in Malaysia and all of them are prepared with necessary precautions. But often my mum makes chocolate milk for me but the taste becomes different. She adds sugar with milk, adds some liquid chocolates with the blend of sugar and milk and then she adds some cocoa powder. She blends all the ingredients into a blender. But I think she makes a mistake here and thus the taste is a bit different from those I buy from the stores. Usually, chocolate milk preparation needs sugar powder but my mum uses the sugar without making it powder. So, often I have to grind the sugar with my teeth when I drink the homemade chocolate milk.
Drinks are popular among the Malaysian but since this is a Muslim country, hard drinks are banned here, though one can manage those with investing some efforts. But a majority of the people here do not drink the hard drinks rather they prefer the soft drinks. In fact, people of all ages take soft drinks which are mentioned above but very few of them take chocolate milk. They believe that chocolate milk is only for children as it tastes chocolate. But they have a completely wrong idea. In fact, chocolate milk is filled with protein and minerals necessary for the human body. Milk is enriched with all the necessary elements that form the human body while chocolate also has some food value than the chemicals used to prepare the soft drinks. Besides, the chocolate milk is tastier than the other drinks I have tasted so far. Unfortunately, most of the people are unable to understand the benefits of chocolate drinks and thus the number of people drinking chocolate milk is fewer.
I prefer chocolate milk for numerous reasons. The first and most important thing is that chocolate milk is a kind of fluid that helps to serve protein in the body which is helpful for muscle repair. When someone works for long, a glass of chocolate milk is able to replenish the damages caused by the physical labour. It restores energy on a human body and preparation process is also less complex than the other drinks, especially soft drinks. Chocolate milk is available everywhere and the taste of the drink is delicious. Milk is considered a recovery option for people of every age but there are some people who do not prefer to have milk and chocolate milk is a potential drink for them. They will drink it for its exceptional taste and thus their deficiencies will be refilled shortly. In fact, chocolate milk is highly important for preserving a good health. Thereby, chocolate milk is my favourite drink

Talk about your favorite food or drink and how to make it.
Hello eveyone,
I'd like to tell you about my favourite food. It's beef noodle. It's made if rice, beef, and many kinds of herbs. I usually eat beef noodle in the morning. My favourite restaurant is Cuong Noodle. It's a small restaurant located on Tran Hung Dao street in Ho Chi Minh city. Whenever i eat beef noodle, it always makes me have a special taste. Hanoi capital is famous for beef noodle. What's more, it's also well-known for a lot of delicious foods. For example Omai, frilled rice...
At home, my mother makes beeff noodle very well. She often makes it when my family get toghether. We enjoy the happy time when we have beef noodle at home.
I often have flu. When I have flu, I often feel very tired and miserable. However, I have some ideas to avoid the illness. Firstly, it very good if you eat more vegetables and fruits. It problems many vitamins such as vitamin A, B, C, etc. Secondly, don't drink too much cold water because it is very bad for our health, especially our throats. Finally, it is very important to keep us warm in the winter. It will help us avoid getting flu. My mother often takes care of me when I have cold or flu. She always reminds me that : " You should take the medicines as the doctor gave ". In the future, I hope I will avoid the disease because of the things I do above.
Pho is one of the Vietnam traditional food. It first appeared in Vietnam a long time ago. Pho is made from rice noodles, beef stock, meat such as beef or chicken, and some kind of herbs. First, the beef stock is boiled to make broth. In the boiled, they often add sliced ginger and roasted onions to get that 'pho' smell. Then, rice noodles and beef or chicken are quickly boiled, then put into a bowl with some herbs. Finally, hot broth is poured into the bowl, making a lovely bowl of pho. When we eat Pho, we use chopsks and a spoon. Before we eat the noodles, we should take a sip of hot broth. Then, we can smell the taste of roast ginger and onions. and we can make sure it isn't too hot. In Hanoi, Pho is not expensive. For only 25,000 VND, we can eat a deliciuos bowl of Pho. People sell it from early morning until late at night. So, we can eat Pho at anytime we want to. In Hanoi, Pho is very important because it has a unforgettable taste, so people who come to visit Hanoi need to try it .

6)When I was small, I went to the Temple of Literature – the Imperial Academy. But I can’t remember now. I only know the Temple of Literature – the Imperial Academy is considered the first university in VN. It very famous so many tourist visit there. It is located in the centre of Ha Noi. The Temple of Literature was founded in 1070. Ly Nhan Tong decided to build the Imperial Academy in 1076. In 1483 the Imperial Academy was renamed Thai Hoc Vien. The university was a great success and many Vietnamese scholars gradute from this university. Chu van An is considered one of the most famous teachers there. It is also famous for 82 Doctors’ stone tablets. The Doctors’ stone tablets were first erected by King Le Thanh Tong in 1484. And in 2010, the 82 Doctors’ stone tablets were recognised by UNESCO. The four statues( Ly Thanh Tong, Ly Nhan Tong, Le Thanh Tong and Chu Van An) were built by Ha Noi people. They are the founders and the developers of the Temple of Literature – the Imperial Academy.
I want to visit there again in the future. Thanks for listening!
