UNIT 11: SOURCES OF ENERGY

2. 1. WARM UP:
* Activity 1: watch the video and list some sources
of energy in this video

3. List some sources of energy you have seen :
- Electrical energy
- Heat energy
- Muscular energy
- Solar energy
- Hydel energy
- Wind energy

4. * Activity 2: Answer the following questions:
1. What sources of energy do you know ?
2. What do you need energy for ?
There are a lot of different sources of energy such as:
electrical , light , muscular , chemical, geothermal
energy and some natural energy as solar, wind, water
energy and so on…
We need energy to live and work, to
cook meals, to light, heat or cool the
house, to run machines...

UNIT 11: SOURCES OF ENERGY

6. At present, most of our energy comes from fossil fuels (oil, coal, and natural gas). However,
such reserves are limited. Because power demand is increasing very rapidly, fossil will be
exhausted within a relatively short time. Therefore, people must develop and use alternative
sources of energy
One alternative sources is nuclear energy. Nuclear energy can provide enough electricity
for the world’s needs for hundreds of years, but it can be very dangerous. Another alternative
source of energy is geothermal heat, which comes from deep inside the earth. Scientists use
this heat to make energy. However, this energy is available only in a few places in the
world.
The sun, water, and the wind are other alternative sources of energy. The wind turns
windmills and moves sailboats. It is clean source of energy, and there is lots of it.
Unfortunately, if the wind does not blow, there is no wind energy. When water moves from a
high place to a lower place, it makes energy. This energy is used to create electricity .Water
power gives energy without pollution. However, people have to build dams to use this
energy. And as dams cost a lot of money, water energy is expensive.
The sun releases large amounts of energy every day. This energy can be changed into
electricity. Many countries use solar energy for their daily life. Solar panels on the roofs of
houses can create enough energy to heat or cool an entire house. Solar energy is not only
plentiful and infinite but also clean and safe.
Although there are some disadvantages, the potential of alternative sources of energy is
great. However, how to make full use of these sources of energy is a question for researchers
Listen to the tape:
