Its all about , How HYDEL ENERGY works? Its advantages and disadvantages,and many more.. And very helpful for school projects....

2. Power or energy plays a vital role in our
lives. We need power for many purposes
such as for industry, agriculture ,
transport, etc.
Power resources may be broadly
categorized as conventional and non
conventional .

3. Conventional resources are those which
have been in common use ; such as
firewood, coal or thermal power ,
petroleum , natural gas and hydel power.
Non conventional resources are the
sources of energy which are being
produced continuously in nature.

4. Hydro electric power also known as
hydel power is an environmentally
friendly way to generate electricity.

5. A hydroelectric power plant consists of
a high dam that is built across a large
river to create a reservoir, and a station
where the process of energy conversion
to electricity takes place.

7. The best place for a hydro-electric
power station is up in the mountains.
This is because of
Low temperature
High rainfall

8. Generation of hydel power includes the
following steps:
The collection of run off water
Water gets stored in the form of
potential energy.
Water falls in the form of kinetic
energy near the bottom of the dam.

9. Gravity causes it to fall on a turbine
propeller, which is turned by the moving
water .
The shaft from the turbine goes up into
the generator, which produces the
power.
These power lines carry the generated
electricity to our homes.

11. The following are the advantages of
hydel energy
It ensures constant electricity supply.
Generation of electricity can be easily
regulated.
It forms a picturesque.
No green house gases are produced.
i.e. it is eco friendly.
Dams are designed to last many decades.

12. The following are its disadvantages:
Dams are very expensive to build.
They must be operate for many decades
to become profitable.
Displacement of residents of that area.
Serious geological damage.
Water supply problems.
The decay of vegetation along the
riverbed can cause the buildup of
methane.

13. It can be used for the following purposes:
Commercial electric power.
Irrigation.
In water mills and sawmills.
Domestic electric power.
