SOURCES OF ENERGY IN THE PHILIPPINES

The Philippines is now reducing its dependence on fossil fuels. It is tapping its abundant energy resources, such as the sun, wind biomass, and geothermal energy. Geothermal Hydropower plants have been built to serve as major sources of electricity in many areas.

The Philippines has some large solar

projects also. One of these is the Philippine

National Company solar home system in Luzon which provides

electricity to households in the

Cordilleras, the Visayas, and some

remote areas in Mindanao. There is also a large on-grid solar photovoltaic

power plant in Cagayan de Oro named Cagayan

Electric Power and Light Company, Inc.

(CEPALCO).

SOLAR ENERGY

Solar Energy is the radiant energy from the sun that strikes Earth. The Sun is the source of almost all the energy that is used on Earth. It can be converted into other forms of energy, such as heat and electricity.

Solar Energy, when converted to heat energy, can be used to heat water for use in homes and other buildings. It can be converted to electricity with the use of photovoltaic solar cells. These solar cells change sunlight directly into electricity. They can also supply water to watches and calculators. There are also solar power plants which indirectly generate electricity. The heat collected from the solar thermal collectors enables a fluid to produce steam that runs a generator.

Solar Energy is free and clean; its supplies are unlimited. Its use does not

produce air and water pollution. A disadvantage, however, is that the

amount of sunlight that arrives as the surface of Earth is not constant. It

depends on the location, time of day, time of year and weather conditions.

Also, the photovoltaic cells are made of silicon and produce some waste products in the manufacturing process which can

affect the environment.

HYDROPOWER ENERGY Is the widely used renewable energy source to

generate electricity. It is the energy in moving water. The amount of available energy in moving water is determined by its flow or fall. Fast flowing falling water in rivers or falls carries a great deal of energy. When water flows through the pipe, it pushes against and turns the blades in a turbine to spin a generator to produce electricity. The force of a river current can apply the necessary pressure to produce energy while a storage system such as dams and reservoirs where water is accumulated, can release water when the demand for electricity is high.

Hydropower is regarded as an ideal fuel for generating electricity because it is almost free, does not have waste products, and does not pollute the air or the water . However, it can also change the environment by affecting natural habitats.

GEOTHERMAL ENERGY

Is heat from within the earth. Steam comes from hot underground springs. Pumping water down to hot rocks that are deep underground will also produce steam that rises to the surface.

Geothermal heat is a renewable source of energy because water is replenished by rainfall and heat is continuously produced inside the earth.
