3. Energy
Energy is the capacity
that has some objects
to transform an energy
source into work. For
example: a car
transform gasoline into
motion.
The energy is measured
in joules (J) and
calories (cal).
4. TYPES OF ENERGY
Mechanical Energy: An example of
- Kinetic Energy is the mechanial energy is:

motion.
- Potential Energy is the
energy that produce
objects when they are
above the soil.

5. TYPES OF ENERGY
Electrical Energy is
the energy
associated with an
electric current.
For example: like the
energy that use a
bulb.
6. TYPES OF ENERGY
Electromagnetic
energy is the energy
that transport the
electro magnetic
waves.
For example: a
television, a radio.
7. TYPES OF ENERGY
Sound energy is the
energy produced by
the sound waves
produced through
vibrations.
For example: a
mobile.
8. TYPES OF ENERGY
Chemical energy is
the energy that can
be released or
absorbed during
chemical processes.
Example: baterie.
9. TYPES OF ENERGY
Nuclear energy is the
energy produced
during nuclear
reactions.
Example: a nuclear
station.
10. TYPES OF ENERGY
Thermal energy or
Calorific energy, is
the energy that
come from the
vibration of particles
in matter.
Example: a heater.
11. ENERGY SOURCES
Energy sources are the natural sources that
produce many forms of energy. This energy is
used for specific uses.
This energy is classified in renewable and non-
renewable energy.
12. NON-RENEWABLE E.S
Non-renewable E.S, is the energy that are
limited.
Inside non-renewable E.S there are:
-Nuclear -Natural gas
-Coal -Radioactive materials
-Petroleum
13. RENEWABLE E.S
Renewable E.S are the energy sources that are
unlimit.
Inside Renwable E.S there are:
-Hydraulic energy -Biomass
-Solar energy -Marine energy
-Wind energy -Geothermal energy

enviromental
problems. -Rising Water
Temperature
-Atmospheric Pollution.
15. ENVIRONMENTAL
IMPACT
Increased Greenhouse
Effect: CO is release
2
from fossil fuels and
make the tempeture of
the earth increase, and
this happens when that
carbon dioxide traps the
sun's rays in the
atmosphere.
16. ENVIRONMENTAL
IMPACT
Acid Rain is the sulphur
and nitrogen oxide
produced when you
burn petroleum and
coal. That elements
react with water vapour
and produce negative
actions to the
environment.
17. ENVIRONMENTAL IMPACT
Oil Spills :
When petroleum is
released into the sea
is produced a
ecologycal desaster
in marine andn costal
ecosystems
19. ENVIRONMENTAL IMPACT
Rising Water
Temperature:
The temperature in
water of rivers and
sea encrease
becouse of the
thermal power station
, and it has a negative
effect for animals and
plants
21. ENERGY POWER STATION
An Energy power station is a place where
elctric power is generated. The most usual
power station is the Thermal P.E where energy
is produced by the transformation of heat into
motion,the heat is usually obtained by
combustion of a fuel. It produced a bad
ecologycal effect.
22. WIND TURBINE
A french engineering has discover a new use for
wind turbine,this turbine is called WMS1000
and has the amazing capacity to transform
humid air into drinking water. It can be a good
way to help arid countries where water
resources are scarce.
