OBSERVE THE PICTURE BELOW.

WHAT IS ENERGY?

Energy is the ability to
do work.

“TENAGA IALAH KEUPAYAAN UNTUK MELAKUKAN KERJA.”

Let us find out the
ENERGY SOURCES

around us.

“Mari kenali sumber tenaga yang terdapat di sekeliling kita.”

ENERGY SOURCE The Sun is the main source of
energy.The energy from the Sun is
used to generate electricity
through the use of solar panels.

1. Sun Matahari merupakan sumber tenaga yang paling
(Matahari ) utama. Tenaga Matahari boleh digunakan untuk
menjanakan elektrik melalui panel suria.

ENERGY SOURCE Flowing water rotates the turbine in
the dam to generate electricity.
2. Water
(Air) Air yang mengalir menggerakkan turbin di empangan
untuk menjanakan elektrik

Empangan
hidroelektrik

ENERGY SOURCE Blowing wind rotates the windmill
to generate electricity.
3. Wind
(Angin) Angin yang bertiup menggerakkan kincir angin untuk
menjanakan elektrik.

Kincir angin

ENERGY SOURCE Biomass is a substance from plants
or animal faeces used to produce
4. Biomass fuel and generate electricity.
(Biojisim)
Biojisim ialah bahan daripada tumbuh-tumbuhan
atau tinja haiwan yang digunakan untuk
menghasilkan bahan api dan menjanakan elektrik.

ENERGY SOURCE Geothermal is also a
source of energy derived
5. Geothermal from the heat of hot rocks
(Geoterma) beneath the surface of
Earth. This heat is used to
rotate the turbine to
generate electricity.

Geoterma juga merupakan sumber
tenaga yang diperoleh daripada haba
batuan panas di bawah permukaan
Bumi untuk menjanakan elektrik.

ENERGY SOURCE Nuclear substances such
as uranium are used to
6. Nuclear generate electricity at
(Nuklear) nuclear power stations.

Bahan nuklear seperti uranium
digunakan untuk menjanakan elektrik di
stesen janakuasa nuklear.

ENERGY SOURCE Waves rotate the turbine
in the ocean to generate
7. Waves electricity.
(Ombak)
Ombak menggerakkan turbin di dalam
laut untuk menjanakan elektrik.

ENERGY SOURCE Fossil fuels such as
petroleum, natural gas,and
8. Fossil fuels coal are burned to generate
(Bahan api fosil) electricity.

Bahan api fosil seperti petroleum, gas asli
dan arang batu dibakar untuk menjanakan
elektrik.

Coal
( arang batu )
