HYDROPOWER

HYDROPOWER

Hydro” means “water” in Latin – so “hydro power” is made from water. Hydro energy is electricity made using water. Sounds weird, right? Especially since it's dangerous to mix the two. The water never comes in contact with the electricity. How it works is, water flowing down a river is used to spin turbines inside a generator. Large rivers with fast flowing water work the best.

Hydropower is clean. It doesn't produce any greenhouse gases or other air pollution. It also doesn't generate any waste products that might need special handling or disposal. Because it's carbon-free energy, hydropower doesn't burn fossil fuel. Like solar and wind energy, electricity from water is renewable. Water from rivers is a natural resource so it doesn't come with some of the problems other energy sources have, such as cost and insufficient amounts. Hydropower converts kinetic energy from falling water into electricity and never uses up more water than nature produces.

Hydropower doesn't cost a lot of money. On average, the cost for hydropower operations and maintenance is only one-third the cost of a nuclear or a fossil fuel powered facility, Another good thing about hydropower is it's flexible and reliable. Hydropower can be turned on almost immediately to meet the fast growing electricity demands. If you have a stream running through your backyard does that mean you could use it to create energy? Possibly. If you live near the ocean you might even be able to use the energy from waves to make electricity in the future.

NATIONAL TEACHERS' DAY- SEPTEMBER-5

NATIONAL TEACHERS' DAY

Teachers have an influencing role in the life of a student. They are like beacons of light guiding us in our life. A teacher moulds us and in the process shapes our future. What we learn from our teachers remains with us throughout our life giving us direction. Teacher's Day is celebrated throughout the world. By celebrating National Teacher's Day we thank our teachers for providing us their invaluable guidance.

Teachers Day will be celebrated at different dates in different countries. UNESCO inaugurated 5 October as World Teachers' Day. Teacher's Day, also called Teachers' Appreciation Day or National Teacher's Day, is celebrated on 5th of September in India. The day 5th of September was selected as it is the birthday of a great teacher and the former President of India, Dr. Sarvepalli Radhakrishnan. When some of his students and friends approached him and requested him to allow them to celebrate his birthday, he said "instead of celebrating my birthday separately, it would be my proud privilege if September 5th is observed as Teacher's day". From then onwards, 5th of September has been observed as Teachers Day in India. Sir Sarvepalli Radhakrishnan (1888-1975) was one of the most profound philosophers of this century, author and educationalist. In India, September 5 is celebrated as Teacher's Day in his honor

Since time Immemorial, Indians have respected their teachers. Earlier we used to call our teachers 'Guru'. And now it's the modern 'Sir' or 'Madam'. Nonetheless, the role of teachers has remained the same. They were and they are our guides, creating conditions conducive to our overall development. And we will always be thankful for their constructive support. As an expression of our thanks, we celebrate Teacher's Day in India.

On Teacher's day schools students dress up as their teachers and take lectures in classes that are assigned to the teachers they represent. Sometimes teachers sit in their classes as students, reliving again the time when they themselves were students. Thus, both students as well as teachers get to understand each other's position. Also, functions are organized in schools on Teacher's Day. Students present various programs for the entertainment of their teachers. In addition to being the day when the efforts of teachers are recognized, it provides a chance for healthy interaction between students and teachers.
