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...

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?
1. Solar energy can be used in remote areas where it is too ____expensive___ to extend the electricity power. (EXPENSE)
2. I think I’d prefer something a little less ___energetic____. (ENERGY)
3. The potential of ____alternative___ sources of energy is not only plentiful but also clean and safe. (ALTERNATE)
4. ____Renewable___ resources are a very important part of saving energy and the environment. (RENEW)
5. In order to save energy, we need to find other clean, and ___effective____ sources of energy. (EFFECT)
6. The weather is very ____changeable___ at this time of year. (CHANGE)
7. The energy ___consumption____ will be reduced in the future. (CONSUME)
8. We will solve the problem of energy ____shortage___ by using solar energy. (SHORT)
