Water
is one of our basic necessity in life
could also be a source of our other necessity
who would have thought that water
Hydroelectric power (often called hydropower) is considered a renewable energy source. A renewable energy source is one that is not depleted (used up) in the production of energy.

Through hydropower, the energy in falling water is converted into electricity without “using up” the water.

Hydropower energy is ultimately derived from the sun, which drives the water cycle. In the water cycle, rivers are recharged in a continuous cycle. Because of the force of gravity, water flows from high points to low points. There is kinetic energy embodied in the flow of water.

Once a dam is constructed, electricity can be produced at a constant rate.

If electricity is not needed, the sluice gates can be shut, stopping electricity generation. The water can be saved.
When is use, electricity produced by dam systems do not produce green house gases. They do not pollute the atmosphere.

The flooding of large areas of land may increase in risk
Like other dams, it is expensive to build and must be built to a very high standard.

People living in villages and towns that are near the plant, must move out.

Hydroelectric power remains the most attractive renewable energy investment in the Philippines as eight new mini hydro projects gain approval for construction this year.

LA MESA DAM
is a 700-hectare water reservoir built to supply water to Metro Manila and its suburbs.
ANGAT DAM
is a concrete water reservoir embankment hydroelectric dam that supplies the Manila metropolitan area water.
SAN ROQUE DAM
operated under San Roque Multipurpose Project is a 200 meters tall, 1.2 kilometer long embankment dam on the Agno River
Hydropower is an important renewable energy source world wide...
even in desert homes, we can experience new technologies with the power of water.
