- What you should do to save energy

With fast growth of civilization there is also an ever mounting need for energy. Energy may be in the form of fuels or electricity. Petrol is a liquid fuel which is used widely nowadays. But this kind of fuels is likely to be exhausted at the rate man is using it recently.

To meet the challenge, various methods have been suggested. One is to minimize the man’s demand in using the energy. Non-essential consumption should be minimized. During certain days of the year, people all over the world turn off the electricity for 1 hour to save the energy. Modern gadgets consuming energy should only be used when they are absolutely necessary.

Energy conservation is possible through modernization of plant and equipment. People should replace the obsolete equipment by the modern ones.

Energy can be saved on transport by the following methods. People should commute by the rail rather than by cars and vans. The transport must be improved with a view to sparing the energy. Cities must be planned in such a way that the commuting distance from this place to others is minimized.

In industry, many things could be done to reduce waste of energy or to economize energy. The machine maintenance needs to be tightened; heater must be utilized properly. When systems are streamlined, economy in fuel is obvious. Instead of using materials requiring higher energy, those which require lower energy should be used.

We hope man with his ever rising urge for existence will cope up with this urgent problem and find alternatives.

Dear guests, I’d like to talk to you today about renewable and non-renewable energy.

Fossil fuels are nom-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 win 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.

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.

Hello students. Today I'd like to tell you some information about types and sources of energy. Energy is classified into two main groups: renewable and non-renewable.The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions, so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills....

Hello students. Today I'd like to tell you some information about types and sources of energy. Energy is classified into two main groups: renewable and non-renewable.The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions, so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills. Unfortunately, solar energy can be only used during the daytime but not during night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth's surface to the top and can create environmental changes.

Non-renewable energy is the energy taken from other sources that are available on the earth. They are limited and will run out in the future. They can't be re-generated in a short time. Fossil fuels - natural gas, oil and coal - are examples. They are cheap and easy to use. However, when burnt, they release toxic gases in the air, so they cause serious environmental changes such as global warming. And the important thing is that non-renewable sources will expire someday.

71. How many main groups of energy sources are there? 

A. 2 B. 3 C. 4 D. 5

72. What is NOT mentioned as a source of renewable energy? 

A. solar B. wind C. coal D. tides

73. What is TRUE about renewable energy sources?

A. having high carbon emissions B. plentiful and can be generated again

C. environment-unfriendly D. always available

74.What are the features of non-renewable energy? 

A. unlimited and run out in the future B. can be re-generated in a short time

C. expensive but easy to use D. limited and run out in the future

75. What is not an example of non-renewable energy sources?

A. oil B. solar C. natural gas D. coal

cảm ơn bạn nha bạn học giỏi TA ghê luôn yeuhehe

There are some tips to save power which I think are very easy to apply. Firstly, we should use energy saving light bulbs in our house. It will help us to reduce our electricity bill. Secondly, we should use public transport if we need to go long distance. We can use bicycles for short distances. I think it is good for our health and economical. And remember, before going to bed, we should turn off all lights and other unused electrical devices. It's an easy way to save our planet.

Mr Lam is giving a lecture on energy sources. Read the text and choose the best option (A, B, or C) to complete the sentences.

Hello, class. Today I'd like to tell you about two energy sources. They are non-renewable sources and renewable sources.

Non-renewable sources are coal, oil and natural gas. We can use these sources to produce energy. They are cheap and easy to use. People use them a lot. But they are very limited and will run out soon.

Renewable sources come from the sun, wind or water. When energy comes from the sun, we call it solar energy. Wind energy comes from the wind, and hydro energy comes from water. Renewable sources are available, clean and safe to use. But they are expensive to produce.

In the future we will rely more on renewable energy sources. They are better for the environment and they will not run out.

1. Non – renewable sources are cheap and _________.

A. available

B. easy to use 

C. expensive

2. _________come from the sun, wind or water.

A. Renewable sources

B. All energy sources

C. Non-renewable sources

3. When energy comes from water, we call it_________.

A. wind energy 

B. solar energy

C. hydro energy 

4. Renewable energy sources are better for_______.

A. the environment 

B. our cars

C. hydro energy

Tạm dịch bài đọc: 

Chào cả lớp. Hôm nay tôi muốn nói với các bạn về hai nguồn năng lượng. Chúng là những nguồn không thể tái tạo và những nguồn có thể tái tạo.

Các nguồn không thể tái tạo là than đá, dầu mỏ và khí đốt tự nhiên. Chúng ta có thể sử dụng những nguồn này để sản xuất năng lượng. Chúng rẻ và dễ sử dụng. Mọi người sử dụng chúng rất nhiều. Nhưng chúng rất hạn chế và sẽ hết sớm.

Các nguồn tái tạo đến từ mặt trời, gió hoặc nước. Khi năng lượng đến từ mặt trời, chúng ta gọi nó là năng lượng mặt trời. Năng lượng gió đến từ gió, và năng lượng thủy điện đến từ nước. Nguồn tái tạo có sẵn, sạch sẽ và an toàn để sử dụng. Nhưng chúng đắt tiền để sản xuất.

Trong tương lai, chúng ta sẽ dựa nhiều hơn vào các nguồn năng lượng tái tạo. Chúng tốt hơn cho môi trường và chúng sẽ không cạn kiệt.

1. Nguồn không tái tạo được rẻ và _________.

A. có sẵn

B. dễ sử dụng

C. đắt

2. ________nhận được từ mặt trời, gió hoặc nước.

A. Nguồn tái tạo

B. Tất cả các nguồn năng lượng

C. Các nguồn không thể tái tạo

3. Khi năng lượng đến từ nước, chúng ta gọi nó là_________.

A. năng lượng gió

B. năng lượng mặt trời

C. năng lượng thủy

4. Các nguồn năng lượng tái tạo tốt hơn cho ____.

A. môi trường

B. xe của chúng tôi

C. năng lượng thủy
