Almost all our energy comes from oil, coal, and natural gas. We call them fossil fuels. The earth’s fossil fuels are running out. What will happen when there is no coal, oil and gas on earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy from the sun, the wind, and the water.
Solar energy is unlimited. The sun supplies all the energy used to grow plants, to evaporate water for rain, and to maintain the temperature of the planet. All are necessary for human life. If we are able to collect solar energy, we will be sure to have this abundant source of power.
1. From which do plants on the earth get energy?
A. Stars

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
Our non-renewable energy sources such as coal, oil, and natural gas will (1) _______run___ out of in the future. That's the (2) ____reason______ why we are looking for alternative sources of (3) _______energy___ which are cheap, clean and effective. These (4) ____kinds______ of energy will not cause (5) _____pollution_____ or waste natural resources. (6) _____Renewable_____ power is one of them. It's currently the cheapest source of large-scale renewable energy.
Most wind energy is produced from turbines that have three 60-meter-long blades. The wind spins the blades, which turn a shaft connected to a generator that produces (7) ____electricity______. Now, mass production and technology advances are (8) ______made____ turbines cheaper. In 2000, cumulative wind capacity (9) ____of ______the world was 17,000 megawatts. Fifteen years later, this number increased sharply to 430,000 megawatts. It is predicted that with this pace of growth, (10) in 2050 one third of the world's electricity needs will be fulfilled by wind power.
VI . Read , answer the questions . 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 .

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.
