Dear guests, I’d like to talk to you today about renewable and non-renewable energy.

Fossil fuels are non-renewable energy sources. They include oil, coal, and natural gas. They can be used to create energy, generate electricity, or drive big machinery. Unfortunately, they are harmful to the environment. Viet Nam still relies mostly on non-renewable energy sources, however, hydro power is increasingly used here too.

Hydro and nuclear power can generate a great deal of energy. They are renewable and plentiful. However, hydro power is limited because dams cannot be built in certain areas. Nuclear power can provide enough electricity for the world’s needs, but it is dangerous.

The sun and the wind are other alternative sources of energy. The wind turns turbines to make electricity. Solar power can be converted into electricity. It can be used to heat or cool our houses. Although there are some disadvantages, these alternative energy sources can offer abundant amounts of clean, safe electricity. They will be valued more and more in the future in Viet Nam.

1.How many types of energy sources are mentioned in the text? What are they
Two, they are renewable and non-renewable.
2.What are the disadvantages of hydro and nuclear power?
Hydro power is limited because dams can not be built in certain areas. Nuclear power is dangerous.
3.Why do you think the wind and the sun are called alternative sources of energy?
Because they are natural sources of power and we use then instead of non-renewable sources.
4.What types of energy does Vienam use most?
We use non-renewable source of energy the most but we are increasingly using hydro power
5. What does the professor think VietNam will use more in the future
He think VietNam we use the wind and the sun as althernative sources of energy in the future.

renewable
Generate a great deal of energy
Can not built dams in certain areas
Comes from water
hydro
Talk about the advantages and disadvantages of each type of energy source
Hydro power is a renewable source of energy because it come from water. It is cheap and plentiful. Unfortunately, dams can only be built in certain areas.
