1. Renewable Energy
Chapter Objectives:
Define the Electricity.
List the types renewable energy.
Describe how it works.
Recognize the advantages and
disadvantages of renewable energy.
Chapter Outline:
1. 1 Definition of Electricity.
1.2 Types of electricity.
2.1 What is Renewable Energy?
3.4Conclusion.
3.2 Questions:
2. 1.1 Definition of Electricity
A type of energy fueled by the transfer of electrons from positive and negative points within
a conductor. Electricity is widely used for providing power to buildings, electric devices, and
even some automobiles. A number of individuals are responsible for the development of
electricity, but the most notable one is Benjamin Franklin and his flying kite experiment .
Franklin was able to determine that lightning was a form of electrical discharge.
We use the electricity in all our lives use it in home, in work, in car, in mobile, in school in
everything . the live will be very difficult without electricity.
1.2 Types of electricity
We have two types of electricity:
5. 1.3 WHAT IS RENEWABLE ENERGY?
RENEWABLE ENERGY USES ENERGY
SOURCES THAT ARE CONTINUALLY
REPLENISHED BY NATURE—THE SUN, THE
WIND, WATER, THE EARTH’S HEAT, AND
PLANTS. RENEWABLE ENERGY
TECHNOLOGIES TURN THESE FUELS INTO
USABLE FORMS OF ENERGY—MOST OFTEN
ELECTRICITY, BUT ALSO HEAT, CHEMICALS,
OR MECHANICAL POWER.
6. 2.1 SOLAR POWER:
Solar panels are devices that convert light into
electricity. They are called "solar" panels
because most of the time, the most powerful
source of light available is the Sun.
7. DisadvantagesAdvantages
1-Dose not produce
energy in the
absence of sun.
2-Do not give high
electricity as much
as we need in every
house or factory.
1-Clean energy
does not pollute the
environment.
2-Easy to install.
3-Save money.
8. 2.2 WIND ENEGY:
TRANSFORM THE WIND TO ELECTRICITY BY PUTTING FANS
DRIVEN BY WIND, THE FANS MOVE THE TURBINE AND THE
TURBINE PRODUCES ELECTRICITY.
10. 2.3 GEOTHERMAL ENERGY:
IT THE HEAT ENERGY OF THE EARTH, WHERE THE HIGH
TEMPERATURE IN THE GROUND BY THE EXTRACTION OF THIS
ENERGY CONVERTED INTO ELECTRICITY.
11. DisadvantagesAdvantages
1-Very expensive at
first.
2-Some of the
underground power
stations caused a
geological
imbalance which
caused strong
earthquakes.
1-Clean energy
does not pollute
the
environment.
2-Produced in
constant and
constant quantities.
3- It work 24 hour
don’t need a certain
time to generate.
12. TIDAL ENERGY:
TIDAL ENERGY OR LUNAR ENERGY IS A KIND OF MOTION ENERGY THAT IS
STORED IN THE CURRENTS RESULTING FROM THE TIDES RESULTING NATURALLY
FROM THE GRAVITY OF THE MOON AND THE SUN AND THE ROTATION OF THE
EARTH AROUND ITS AXIS, THIS ENERGY IS THEREFORE CLASSIFIED AS
RENEWABLE ENERGY.
13. DisadvantagesAdvantages
1-there is little chance of
exposure to fish passing
near currents for some
hazards.
2-Limitations of tidal
energy: limitation is one of
the most severe
disadvantages of tidal
energy, as it is difficult to
exploit it in the necessary
places that have a
significant change in water
levels.
1-Not affected by
seasons and
weather.
2-A clean source
and friendly
environment.
15. DisadvantagesAdvantages
1-Hydropower is used only
in areas where there is
sufficient supply of
continuous water.
2-Dams can contain huge
amounts of water and if
these water quantities fail,
it can lead to catastrophic
consequences such as
flooding and destruction of
nearby forests.
1-The efficiency
generating electricity
high power up to 85%.
2-water turbines are
easy to install and
operate, and do not
require high
maintenance costs.
16. 3.1 Conclusion:
We know the electricity very important in
our lives, and our use for electricity
increasing with evolution tech.
After we have known renewable energy
sources, we should strive to use
renewable energy for its benefits to the
environment saving money, and the non-
renewable energy will be finish over the
years and may have no value in the
development of renewable energy.
