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.

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
As the use of alternative energy sources increases, the consumption of the Earth's fossil fuels will also decrease. One watt of energy that is used by solar cells is one less watt used by power plants burning oil or coal. If society hopes to see the next generation have the resources needed to heat homes and drive cars, alternative energy sources are needed today.

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.

In the modern world, people depend on energy to power their everyday lives. A wide range of power-run devices and modern conveniences (1) are taken for granted, and although it may seem that we will not be in danger of living without those conveniences, the fact is that many supplies of energy are running out rapidly. Scientists are constantly (2) searching for new sources of energy to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend (3) on the success of this search. Coal, oil and natural gas are now being used widely. (4) However, not only are supplies of , these supplies are limited, and they are a major source of pollution. Therefore, the existing alternative energy sources must be improved or futher explored and developed. These include nuclear, water, solar, and wind power, as well as energy from new, (5) nonpolluting types of fuels types of fuels. Each of these, however, has advantages and disadvantages.
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.

We are looking for cheap, clean, and effective sources of energy. These types of energy won’t cause pollution or waste natural resources. It will be provided freely by the sun. One percent of the solar energy that reaches the earth will be enough to provide electricity for the whole population of the world. Solar energy will be used by many countries around the world. Solar panels will be placed on the roofs of houses and other buildings and the sun’s energy will be used to heat water. The energy will be stored for a long time. We hope that by using solar energy the problem of the energy shortage will be solved.

Khi việc sử dụng các nguồn năng lượng thay thế tăng lên, việc tiêu thụ nhiên liệu hóa thạch của Trái đất cũng sẽ giảm xuống. Một watt năng lượng được sử dụng bởi pin mặt trời bằng một watt ít hơn được sử dụng bởi các nhà máy điện đốt dầu hoặc than. Nếu xã hội hy vọng thấy thế hệ tiếp theo có các nguồn lực cần thiết để sưởi ấm nhà cửa và lái xe ô tô, thì ngày nay cần có các nguồn năng lượng thay thế.
Nhiên liệu hóa thạch là nguồn năng lượng phổ biến nhất hiện nay, nhưng nó không được coi là năng lượng sạch. Nhiều nguồn năng lượng thay thế khác phải được kết hợp nếu các thế hệ tiếp theo được mong đợi có năng lượng. Nước, gió, nhiệt bên trong Trái đất và mặt trời đều được sử dụng để tạo ra năng lượng. Năng lượng địa nhiệt và năng lượng mặt trời phổ biến hơn. Những ngôi nhà đang được sưởi ấm và làm mát, những chiếc ô tô đang được chạy, và điện được sử dụng tất cả từ những nguồn năng lượng thay thế khác nhau này. Tất cả đều là những ví dụ về năng lượng sạch, tốt hơn cho môi trường vì không gây ô nhiễm.
