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
Like any other type of power, nuclear power has ít own disadvantages. Nuclear power plants discharge radioactive waste during operation. If a nuclear explosion happens, the aftermath will be very serious. The radioactive subtance will absorb into water and land in a large area. It takes a long time and a lot of money to build a nuclear power plant and it also takes a long time. In my opinion, human should exploit safe types of power like solar power, wind power and tidal power to avoid dependence on this dangerous type of power
Write about your favorite film :
There are many interesting films but I think "Just one smile is very alluring" is the best.
"Just one smile is very alluring" is a romantic film, which was directed by Lin Yufen. It is adapted from the novel of the same name by Gu Man. It stars Yang Yang and Zheng Shuang.
The film is about the love story of Xiao Nai and Wei Wei. Xiao Nai is a fourth year student and Wei Wei is a second year student. Xiao Nai is also the CEO of Zhi Yi technology company, he is the most popular student because he is well-versed in both arts and sports. Wei Wei placed second in beauty voting that took place online within the student community. Known by the name "Yixiao Naihe", Xiao Nai is the top player in the game "A Chinese Ghost Story". He suggested Wei Wei get married within the game to participate in a couple competition because Wei Wei is known by the name " Luwei Weiwei", who is the only female player in the top 10 PK ranking . However, Wei Wei never expected the real identity of "Yixiao Naihe", who is described as the cream of the crop in both sports and academics. When Wei Wei discovers his true identity, they have already fallen in love. Together, they overcome numerous misunderstanding and obstacles standing in their relationship.

In present, most of our energy comes fossil fuels
Scientists are searching new sources of powder
Sun, wind and the other alternative sources is energy
We are exhausting the present amount: oil, gas
We will use less solar energy to solve problem energy shortage
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. Ỉ 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

As you know, energy is very important for our lives. We need energy to live and to work. If there isn’t energy, our lives will be very difficult. However, the natural resources are being used up. So we should know how to save energy in the three following ways: First: how to save water. Second: how to save electricity. Third: how to save petrol or gas.
As for me, we should save water by taking a shower instead of a bath; using less hydro. We should save electricity by turning off the lights, TV, air conditioner,…before leaving the room; using low energy light bulbs. To save petrol or gas, we should use public transport for short trips; try walking or cycling instead of using cars or motorbikes; using less gas when cooking. To sum up, we should save energy because to save is also to money as to as natural resources.

Như bạn đã biết, năng lượng rất quan trọng đối với cuộc sống của chúng ta. Chúng ta cần năng lượng để sống và làm việc. Nếu không có nghị lực, cuộc sống của chúng ta sẽ rất khó khăn. Tuy nhiên, các nguồn tài nguyên thiên nhiên đang được sử dụng hết. Vì vậy chúng ta nên biết cách tiết kiệm năng lượng theo 3 cách sau: Thứ nhất: làm thế nào để tiết kiệm nước. Thứ hai: làm thế nào để tiết kiệm điện. Thứ ba: làm thế nào để tiết kiệm xăng hoặc khí đốt.
Solar energy captured by solar panels is a limitless form of energy, as the earth is bombarded with extreme amounts of solar energy every day, according to the National Renewable Energy Laboratory. It's also clean, producing no carbon dioxide, and is very low-maintenance, since solar panels have no moving parts.
Unfortunately, the National Renewable Energy Laboratory says its high installation cost makes it up to four times more expensive than the cost of electricity from a standard utility company. For optimal operation and maximum energy production, it requires year-round sunny weather and is very expensive if repair is necessary, according to the U.S. Environmental Protection Agency.
Topic: SOURCES OF ENERGY
1. Tell me about some renewable sources of energy and nonrenewable sources of energy.
=> Renewable sources of energy : wind,hydro,solar ,...
Non-renewable sources of energy: coal,natural,oil ,.....
2. What types of energy does VN use most?
=> Viet Nam uses non-renewable most
3. What types of energy do you think VN will use more in future ?
=> I think Viet Nam will use renewable sources of energy more in the future
4. Why is the wind/sun called alternative sources of energy?
=> Because it's can replace easily
5. Do you think that saving energy is necessary ? Why ?
=> Yes, I think because nobody of us can live without energy
6. What should you do to save energy for your house or your school?

turn of the lights when we aren't using them
use low energy light bulbs
use public transport
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 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 of them. 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.
No longer is solar energy a fringe energy source, useful only in sunny regions or for charging portable electronics. Thanks to the huge drop in solar component costs over the last few decades and several innovations in materials and production, solar is rapidly becoming an accessible and affordable option for home power.
The cost of solar modules has fallen some 75 percent just since the end of 2009, the International Renewable Energy Agency reports. Solar energy has hit grid parity in a number of markets, including many of the top cities in the U.S. where solar electricity beats out grid prices. And because of new solar financing options such as solar leasing, more home and business owners can find a solar solution that works for them. For those who can't have solar on their own roof but still want the benefits of clean electricity from the sun, community solar programs are an accessible and affordable option.
