We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as...

We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution. On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like nonrenewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the winds blow throughout the year. The five types include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, energy from moving water; biomass, energy from dead plants and microorganisms and finally, energy from the wind.

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.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

1. The Advantages of Clean Energy Sources (Lợi ích của năng lượng sạch)

2. Comparing Different Energy Sources (So sánh các nguồn năng lượng khác nhau)

Choosing the best option for energy can be difficult. Coal power is the most popular form of energy today because coal plants aren't expensive to build. However, they can produce a lot of pollution. Other non-renewable energy sources, like natural gas, are cleaner than coal, but they still aren't good for the environment.

Countries are now moving to renewable sources of energy like wind, solar, and hydroelectric power.

Wind and solar power plants are clean and cheap to run, but they aren't cheap to build. Also, wind turbines are noisy and need windy weather to work well, and solar power doesn't work at night. Hydroelectric plants also don't cause pollution, but they can be expensive to build and affect the environment by stopping fish from moving freely. For these reasons, countries and cities usually choose a mix of energy types.

Lựa chọn tốt nhất cho năng lượng có thể khó khăn. Năng lượng từ than đá là dạng năng lượng phổ biến nhất hiện nay vì các nhà máy than không tốn kém để xây dựng. Các nguồn năng lượng không tái tạo khác như khí đốt tự nhiên, sạch hơn than đá, nhưng chúng vẫn không tốt cho môi trường. Các quốc gia hiện đang chuyển sang các nguồn năng lượng tái tạo như gió, mặt trời và thủy điện. Các nhà máy điện gió và năng lượng mặt trời sạch sẽ và rẻ để chạy, nhưng chúng không rẻ để xây dựng. Các nhà máy thủy điện cũng không gây ô nhiễm, nhưng chúng có thể tốn kém để xây dựng và ảnh hưởng đến môi trường bằng cách ngăn cá di chuyển tự do. Vì những lý do này, các quốc gia và thành phố thường chọn kết hợp các loại năng lượng.

Read the passage below and an answer the question :

We can develop alternative sources of energy,and unless we'll never succeed.instead of burning fossil fuels we should be concentrating on more economic uses of electricity because electricity can be produced from any source of energy. If we didn't waste so much energy,our resources would last longer. We can save more energy by conservativation than we can produce for the same money. Unless we do research on solar energy wind power tidal power hydroelectric plants.... Our fossil fuels will run out and we'll all freeze starve to dealth . Many countries are spending much more time and money on research because the energy from the sun the waves and the winds last forever.we really won't survive unless we start working on cleaner safer scour of energy .

1 Can electricity be produced from any sources of energy?

Yes, it can.

2 What would happen if we didn't waste so much energy?

If we didn't waste so much energy, our resources would last longer.

3 Why are many countries spending much more time and money doing research on energy from the sun the waves and the wind?

Because the energy from the sun the waves and the winds last forever.

4 What will happen unless we start working on cleanr and safer sources of energy?

We really won't survive unless we start working on cleaner and safer scources of energy

Chúng ta sử dụng nhiên liệu hóa thạch trong cuộc sống hàng ngày nhưng chúng còn hạn chế và gây ô

nhiễm. Rất nhiều nhà khoa học đang làm việc chăm chỉ để tìm kiếm một số nguồn năng lượng không mất mát và thân thiện với môi trường.

Năng lượng mặt trời không phải là mới đối với chúng ta vì chúng ta sử dụng nó để làm khô đồ hàng ngày.

Các tấm pin mặt trời bắt tia nắng mặt trời và biến đổi chúng thành điện năng. Chúng ta biết rằng nó có thể tái tạo được bởi vì mặt trời không ngừng tạo ra ánh sáng mặt trời.

Năng lượng gió cũng là một nguồn năng lượng cũ. Trong quá khứ, các nhà thám hiểm sử dụng gió để chèo thuyền đến những vùng đất xa xôi. Một cối xay gió duy nhất có thể bơm nước và tạo ra điện. Để có được nhiều năng lượng hơn cùng một lúc, người ta lắp đặt rất nhiều tuabin gió khổng lồ trên các trang trại điện gió. 

Nếu chúng ta ngừng sử dụng nhiên liệu hóa thạch, hành tinh của chúng ta sẽ xanh hơn. Không có gì để mất khi chúng ta sử dụng năng lượng mặt trời hoặc năng lượng gió.
