Trang 201.What sources of energy do these pictures above
refer to ?
2 What do you need energy for ?
1.They are the wind power, the solar energy and the water power.
2.We need energy to cook meal, to light,
eat, to run machines…
Trang 22At 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 within pollution However, people have to
build
dams to use this energy And as dams cost a lot of money, water energy
is
expensive
Trang 23The sun releases large amounts of energy every day This energy
can be changed into electricity Many countries use solar

Trang 261 What is our major source of energy?
2 How many sources of energy are
mentioned in the test, and which one do you think has the most potential?
1 Our major source of energy comes from fossil
fuels.
