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.Fossil fuel is the most common source of energy today, but it is not considered clean energy.

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.

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 used 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.                                                                                             

Read the passage and decide if these statements are True or False.

1. The consumption of fossil fuels will decrease since alternative sources are used more.

  

2. Alternative energy sources are not necessary today.

  

3. Fossil fuel is considered clean energy.

  

4. Water, wind, the sun are common alternative sources of energy.

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.

Đọc đoạn văn và quyết định xem những nhận định này là Đúng hay Sai.

 ĐúngSai

1. Việc tiêu thụ nhiên liệu hóa thạch sẽ giảm do các nguồn thay thế được sử dụng nhiều hơn.T 
2. Các nguồn năng lượng thay thế ngày nay không cần thiết.F 
3. Nhiên liệu hóa thạch được coi là năng lượng sạch.F 
4. Nước, gió, mặt trời là những nguồn năng lượng thay thế phổ biến.T 
5. Năng lượng sạch là năng lượng không gây ô nhiễm.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

        In this era of increased global warming and diminishing fossil fuel supplies, we must begin to put a greater priority on harnessing alternative energy sources. Fortunately, there are a number of readily available, renewable resources that are both cost- effective and earth - friendly. Two such resources are solar power and geothermal power.

        Solar energy, which reaches the earth through sunlight, is so abundant that it could meet the needs of worldwide energy consumption 6,000 times over. And solar energy is easily harnessed through the use of photovoltaic cells that convert sunlight to electricity. In the US alone, more than 100, 000 homes are equipped with solar electric systems in the form of solar panels or solar roof tiles. And in other parts of the world, including many developing countries, the use of solar system is growing steadily.

       Another alternative energy source, which is abundant in specific geographical areas, is geothermal power, which creates energy by tapping heat from below the surface of the earth. Hot water and steam that are trapped in underground pools are pumped to the surface and used to run a generator, which produces electricity. Geothermal energy is 50,000 times more abundant than the entire known supply of fossil fuel resources and as with solar power, the technology needed to utilize geothermal energy is fairly simple. A prime example of effective geothermal use in Iceland, a region of high geothermal activity where there are over 80 percent of private homes, are heated by geothermal power.

       Solar and geothermal energy are just two of promising renewable alternatives to conventional energy sources. The time is long overdue to invest in the development and use of alternative energy on global scale.

What does the author imply about alternative energy sources?

A. Many different types of alternative energy sources exist.

B. Most alternative energy sources are too impractical for private use.

C. Alternative energy is too expensive for developing countries to produce.

D. Solar and geothermal energy are the effective forms of alternative power.
