Solar energy has good and bad sides. The good thing is that it's clean and does not pollute the air. It also helps us save money because sunlight is free. Solar panels can work for many years and don't need much care. But there're some problems too. The cost to buy and install solar panels is high. Also, they only work well when there is sunlight, so they do not make much energy on rainy days or at night. Even with these problems, solar energy is still a good choice for the future.

Dịch: Năng lượng mặt trời có cả mặt tốt và mặt xấu. Một điều tốt là nó sạch và không gây ô nhiễm không khí. Nó cũng giúp tiết kiệm tiền vì ánh sáng mặt trời là miễn phí. Các tấm pin mặt trời có thể hoạt động trong nhiều năm và không cần bảo trì nhiều. Nhưng cũng có một số vấn đề. Chi phí mua và lắp đặt tấm pin mặt trời khá cao. Ngoài ra, chúng chỉ hoạt động tốt khi có ánh sáng mặt trời, vì vậy vào những ngày mưa hoặc ban đêm, chúng không tạo ra nhiều năng lượng. Dù có những vấn đề này, năng lượng mặt trời vẫn là một lựa chọn tốt cho tương lai.

In the twentieth - century, people depend on unlimited energy to power their everyday lives. A wide range of energy-run devices and modern conveniences are taken for granted, and although it may seem that we will never be in danger of living without those conveniences, the fact is that many supplies of energy are dwindling rapidly. Scientists are constantly searching for new sources of power to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend on the success of this search.

Coal, oil, and natural gas supply modern civilization with most of its power. However, not only are supplies of these fuels limited, but they are a major source of pollution. If the energy demands of the future are to be met without seriously harming the environment, existing alternative energy sources must be improved or further explored and developed. These include nuclear, water, solar, wind, and geothermal power, as well as energy from new, nonpolluting types of fuels. Each of these alternatives, however, has advantages and disadvantages.

Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they pose the daunting problem of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities located far from moving water. Harnessing energy from tides and waves has similar drawbacks. Solar power holds great promise for the future but methods of collecting and concentrating sunlight are as yet inefficient, as are methods of harnessing wind power.

Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resources, such as a combination of solar, water, wind, and geothermal energy and alternative fuels, such as alcohol and hydrogen, will ensure supplies of clean, affordable energy for humanity's future.

Dịch bài đọc:

Trong thế kỷ XX, con người phụ thuộc vào năng lượng vô hạn để cung cấp năng lượng cho cuộc sống hàng ngày của họ. Một loạt các thiết bị chạy năng lượng và tiện nghi hiện đại được coi là điều hiển nhiên, và mặc dù có vẻ như chúng ta sẽ không bao giờ gặp nguy hiểm khi sống nếu không có những tiện ích đó, thực tế là nhiều nguồn cung cấp năng lượng đang cạn kiệt nhanh chóng. Các nhà khoa học không ngừng tìm kiếm các nguồn năng lượng mới để duy trì xã hội hiện đại. Việc dân số trong tương lai có tiếp tục được hưởng những lợi ích của năng lượng dồi dào hay không sẽ phụ thuộc vào sự thành công của tìm kiếm này.

Than, dầu, và khí đốt tự nhiên cung cấp hầu hết năng lượng của nó cho nền văn minh hiện đại. Tuy nhiên, không chỉ nguồn cung cấp các loại nhiên liệu này bị hạn chế mà chúng còn là nguồn gây ô nhiễm chính. Nếu nhu cầu năng lượng trong tương lai được đáp ứng mà không gây hại nghiêm trọng đến môi trường, các nguồn năng lượng thay thế hiện tại phải được cải thiện hoặc tiếp tục khám phá và phát triển. Chúng bao gồm hạt nhân, nước, năng lượng mặt trời, gió và năng lượng địa nhiệt, cũng như năng lượng từ các loại nhiên liệu mới, không gây ô nhiễm. Tuy nhiên, mỗi phương án đều có ưu điểm và nhược điểm.

Các nhà máy điện hạt nhân sản xuất một cách hiệu quả lượng điện lớn mà không gây ô nhiễm bầu khí quyển; tuy nhiên, chúng rất tốn kém để xây dựng và bảo trì, và chúng đặt ra vấn đề nan giải là phải làm gì với chất thải hạt nhân. Thủy điện là không tốn kém và an toàn với môi trường, nhưng không thực tế đối với các cộng đồng ở xa nước di chuyển. Khai thác năng lượng từ thủy triều và sóng có nhược điểm tương tự. Năng lượng mặt trời hứa hẹn rất lớn cho tương lai nhưng các phương pháp thu thập và tập trung ánh sáng mặt trời vẫn chưa hiệu quả, cũng như các phương pháp khai thác năng lượng gió.

Mỗi nguồn năng lượng đều có nhược điểm của nó. Một cách để giảm thiểu chúng là sử dụng ít năng lượng hơn. Những nỗ lực bảo tồn cùng với các nguồn năng lượng tái tạo, như sự kết hợp của năng lượng mặt trời, nước, gió và địa nhiệt và nhiên liệu thay thế, như rượu và hydro, sẽ đảm bảo cung cấp năng lượng sạch, giá cả phải chăng cho tương lai của nhân loại.

Solar energy is obtained from the sun’s radiation and it can be converted to electricity or heat. It is freely available and thanks to advances in technology, we can now harness even more of the solar energy that is continuously available to us. Here are 7 benefits related to this renewable source of energy.

1.Impact on the Environment

Solar energy has the least negative impact on the environment compared to any other energy source. It does not produce greenhouse gases and does not pollute the water. It also requires very little water for its maintenance, unlike nuclear power plants for example, needing 20 times more water. Solar energy production does not create any noise, which is major benefit, since a lot of solar installations are in urban areas.

2.Reduce Your Energy Bill

Generating your own electricity means that you will be using less from the utility supplier. This will immediately translate to savings on your energy bill. Plus, you can also make money by selling the unused electricity, which you have generated, back to the grid. The more energy you produce, the less you will need from the supplier which will increase your energy self reliance.

3.Energy Production Matches the Time Frame of Higher Demand

Energy needs tend to be higher in the 11:00-16:00 time frame and then early in the evening. Naturally, this is the period when the price of the electricity peaks. Solar energy happens to reach its maximum production capacity during those hours. Electricity produced at that time has higher value than if it was generated at night. With the additional electricity input of solar energy, prices in those time frames could be driven down to a level close to those of night hours.

4.Solar Energy Is Applicable Everywhere

As long as there is sunshine, solar energy can be deployed anywhere. This is particularly useful for remote regions with no access to any other source of electricity. There is a vast amount of people around the world with no access to electricity. Independent solar systems could be deployed in those regions and improve the lives of millions of people. Moreover, solar energy is also used to power up spacecrafts and boats.

5.Less Electricity Lost During Long-Distance Transport.

Some of the energy, around 3-5%, is lost during transportation and distribution. The longer the distances between the production and the supply points, the more energy is lost. Those loses might not seem significant but they can influence the performance of the installation in regions with high population density. Having solar panels on the roof or in the yard significantly reduces this distance, therefore increasing the efficiency of the electrical system.

6.Improves Grid Security

The grid is less vulnerable to blackouts if there are many power plants which are spread out. A grid with high penetration of solar energy has thousands of energy production centres which are widely spread out. This improves the security of the grid in case of overload, natural or human-caused disasters.

7.Job Creation

Large part of the cost associated with solar systems comes from the installation of the panels. This contributes to local job creation. Using solar systems boosts the economy and positively affects the local community.

Read the passage, then answer the questions below (2.5pts)

Are you looking for a cheap, clean, effective source of power that doesn't cause pollution or waste natural resources? Look no further than 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 that reaches the Earth is enough to provide power for the total population.

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

Sweden has an advanced solar energy program. There, all buildings will be heated by solar energy and cars will use solar power instead of gas by the year 2015.

Question: Is solar energy an efficient source of power?
