Fossil fuel is the most common source of energy today, but it is not considered clean energy. There are various other sources of alternative energy that must be incorporated if the next generations are expected to have energy. Water, wind, the internal heat of the earth, and the sun are all being harnessed to create energy. Geothermal energy and solar energy are more common. Homes are being heated and cooled, cars are being driven, and electricity is used all from these various alternative sources of energy. All are examples of clean energy, which is better for the environment because it does not cause pollution.

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?

2.What are the disadvantages of hydro and nuclear power?

3.Why do you think the wind and the sun are called alternative sources of energy?

4.What types of energy does Viet Nam use most?

5.What does the professor think Viet Nam will use more in the future?

2.What are the disadvantages of hydro and nuclear power?

Hydro power is limited because dams cannot 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 them instead of non-renewable sources to get the electricity we need.

4.What types of energy does Viet Nam use most?

We use non-renewable sources of energy the most but we are increasingly using hydro power.

5.What does the professor think Viet Nam will use more in the future?

He thinks Viet Nam will use the wind and the sun as alternative sources of energy in the future
