Geothermal energy comes from heat within the Earth and is found in locations in the Philippines like Luzon, Negros, Leyte, and Mindanao. Solar energy comes from the sun and can be harnessed using technologies like solar panels. Hydroelectric energy uses the power of moving water to generate electricity and is found in locations like Pangasinan, Laguna, and Isabela. Wind energy uses wind power to generate electricity and is found in wind farms in Ilocos Norte, Capiz, and Burgos. Biomass energy comes from organic material and plants through photosynthesis and is found in areas like Panay, Iloilo, and Bukidnon.

OF ENERGY: how are
they effective

2. Comes from the heat of the Earth.
It is clean and sustainable.
Resources range from the shallow
ground to hot water and hot rock
found a few miles beneath the
Earth's surface, and down even
deeper to the extremely high
temperatures of molten rock called
magma.

4. SOLAR ENERGY
It is a form of radiant light and
heat from the Sun that is
harnessed using a range of ever-
evolving technologies such as
solar heating, photovoltaic, solar
thermal energy, solar architecture,
molten salt power plants and
artificial photosynthesis.

6. hydroelectric ENERGY
It is also called hydroelectric
power or hydroelectricity
It is a form of energy that
harnesses the power of water in
motion—such as water flowing
over a waterfall—to generate
electricity.

8. “ Wind ENERGY
It refers to the process of creating
electricity using the wind, or air
flows that occur naturally in the
earth's atmosphere.
Modern wind turbines are used to
capture kinetic energy from
the wind and generate electricity

10. BIOMASS ENERGY
Comes from organic material like plants
and animals that are renewable source
of energy.
Biomass contains stored energy from the
sun that are absorb by the plants
through the process of photosynthesis.
When biomass is burned, the
chemical energy in biomass is released
as heat.

12. what
more?

13. disadvantages
High cost. Unfortunately, the technologies that utilise
alternative sources of energy remain relatively expensive.
Issues with the stability of the system. The energy
sector is not only seeking for alternative solutions to lower
carbon dioxide emissions but to meet the rising demand
for energy as well.
Low efficiency. Alternative energy technologies are
relatively new in offices and are not particularly efficient.

14. Environmental
benefits. Low or zero
carbon emission is
without a doubt the
main advantage of
alternative energy over
fossil fuels.
Increased energy
security. Fossil fuels are
unequally distributed
and make the global
economy dependent on
a few exporting
countries.
Advantages
Sustainability. They are renewable which
means that they offer sustainable and stable
energy supply in the long term.
