Read the following passage and decide if it is T or F Many people still believe that natural resources will never be used up. Actually, the world's energy resources are limited. Nobody knows exactly how much fuel is left. However, we also should use them economically and try to find out allternative sources of power. According to Professor Marvin Burnharrm of the New England Institude of Technology, we have to start conserving coal, oil and gas before it is too late; and solar power is the only alternative.

1. Non - renewable sources are being used up. T
2. Many poor people in developing countries do not have little electricity. F
3. Biogas is a new source of energy available for poor people. T
4. Biogas creates a lot of smoke. F
5. The new energy source is not costly T
Energy is fundamental to human beings. Many poor people in developing countries do not have modern sources of energy like electricity or natural gas, with which their life can be improved.
People who live in mountainous areas have to gather wood for fuel. This takes a lot of time. For many people living in rural areas, biogas is the largest energy resource available. The main use of biogas is for cooking and heating, but it can also provide energy for public transport. As biogas is smoke-free, it helps solve the problem of indoor air pollution. Moreover, it’s made from plant waste and animal manure. They cost almost nothing.
The tendency to use renewable energy sources in developing countries is on the increase as non-renewable ones are running outệIn the future, the wind and the sun will be used as the most important environmentally friendly energy sources.
1. Non - renewable sources are being used up. (T)
2. Many poor people in developing countries do not have little electricity. (T)
3. Biogas is a new source of energy available for poor people. (T)
4. Biogas creates a lot of smoke. (F)
5. The new energy source is not costly. (T)
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 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
