Are you looking for a cheap, clean, effective source of power that doesn't cause pollution or waste natural resource? Look no further solar energy from the Sun

At present, most of our electricity comes from the use of coal and gas, oil or nuclear power. This power could be provided by the Sun. One percent of the solar energy thet reaches the Earth is enough to provide power for the total population

Many countries are already using solar energy. Solar panels are plaaced on the roofs of a house and the Sun's energy is used to heat water. The energy can be stored a number of days, so or cloudy days you can use solar energy, too

Questions

1. Is the solar energy an effective source os power?

=>Yes,it is

2.Where are the solar panels placed?

=>They are placed on the roof of a house.

3.Is the solar energy used in Vietnam now?

=>Yes,it is

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_______.

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

SOLAR ENERGY

Sunlight carries huge amounts of energy. You can feel the Sun’s energy when sunlight warms your skin on a summer day. To capture the Sun’s energy, scientists have developed solar cells, called photovoltaic cells. These cells convert sunlight into electricity. When sunlight hits a solar cell, some of the light energy is absorbed. This light energy causes the particles in the solar cell to move faster, and the movement of these particles creates electricity.

In some places, large panels of solar cells harvest sunshine to make electricity for homes and businesses. Solar cells have been placed on cars and appliances, too. Since the Sun sends abundant free energy streaming toward Earth 24 hours a day, people in many parts of the world, not just the sunniest places, have fixed solar cells and solar panels on the roofs of their houses or businesses to lower their energy costs. Experts say that the huge installation of solar panels in sunny regions could generate enough electricity to supply an entire country. Capturing this energy can help overcome our diminishing energy supply. New ways to capture this energy are being developed an the time to maximize efficiency.
