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

My house primarily relies on electricity and gas for energy. Electricity powers most appliances and lighting, offering convenience but contributing to high consumption. Gas fuels the heating system, providing warmth efficiently but releasing emissions. To save energy, I've adopted simple habits: switching to LED bulbs, unplugging devices not in use, and using energy-efficient appliances. I've also improved insulation and sealed drafts to minimize heat loss. Moreover, I'm conscious of water usage, opting for efficient fixtures and practicing conservation. These steps not only save energy but also reduce environmental impact, aligning with my commitment to sustainability.

Chọn chủ đề 2 Comparing Different Energy Sources

(So sánh các nguồn năng lượng khác nhau)

Giải thích: Đoạn văn đi so sánh lợi ích và bất lợi của một số nguồn năng lượng khác nhau.

Tạm dịch:

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. 

In the modern world, people depend on energy to power their everyday lives. A wide range of power-run devices and modern conveniences (1) are taken for granted, and although it may seem that we will not be in danger of living without those conveniences, the fact is that many supplies of energy are running out rapidly. Scientists are constantly (2) searching for new sources of energy to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend (3) on the success of this search. Coal, oil and natural gas are now being used widely. (4) However, not only are supplies of , these supplies are limited, and they are a major source of pollution. Therefore, the existing alternative energy sources must be improved or futher explored and developed. These include nuclear, water, solar, and wind power, as well as energy from new, (5) nonpolluting types of fuels types of fuels. Each of these, however, has advantages and disadvantages.

• Solar energy is a clean and renewable energy source.
• Once a solar panel is installed, solar energy can be produced free of charge.
• Solar energy will last forever whereas it is estimated that the world’s oil reserves will last for 30 to 40 years.
• Solar energy causes no pollution.
• Solar cells make absolutely no noise at all. On the other hand, the giant machines utilized for pumping oil are extremely noisy and therefore very impractical.
• Very little maintenance is needed to keep solar cells running. There are no moving parts in a solar cell which makes it impossible to really damage them.
• In the long term, there can be a high return on investment due to the amount of free energy a solar panel can produce, it is estimated that the average household will see 50% of their energy coming in from solar panels.

• Solar panels can be expensive to install resulting in a time-lag of many years for savings on energy bills to match initial investments.
• Electricity generation depends entirely on a countries exposure to sunlight; this could be limited by a countries climate.
• Solar power stations do not match the power output of similar sized conventional power stations; they can also be very expensive to build.
• Solar power is used to charge batteries so that solar powered devices can be used at night. The batteries can often be large and heavy, taking up space and needing to be replaced from time to time.
