Nowadays, energy is being run out more and more so what should we do to save energy? First, we should use electricity more efficiently. We should turn the light, the television and other electrical appliances off when we are not using them. We can also use low energy light bulbs to save electricity. Second, we should use less private transport. We should travel by bus or train instead of car and motorbike. In addition, we can avoid using cars or motorbikes for short trips. Finally, we should reduce the use of water. Taking showers instead of baths is a good way. Besides, we should turn off the tap when brushing our teeth; this can save 6 liters of water per minute. In conclusion, those ways can save our lives in the future so we should raise our awareness of saving energy
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.
We need to save of energy because nobody of us can lives => live ( sau can là động từ nguyên thể ) without energy. What should we do to save energy? I think we should turn of => off the lights before going to bed, use biogas for cooking at home, go to school by bike,... because we will do to save non-renewable sources of energy. In short, if you follow these simple ways, you will save energy.
We use a lot of energy at home and it costs us a lot. To save energy, we should use low energy light bulbs in our house. It will help us to reduce our electricity bill. Secondly, before going to bed, we should turn off electrical appliances when not using them. Finally, we should turn off the lights in room when we go out, avoid wasting water, shut the kitchen stove when stop cooking.
Tạm dịch:
Chúng ta sử dụng rất nhiều năng lượng ở nhà và chúng ta tốn rất nhiều năng lượng. Để tiết kiệm năng lượng, chúng ta nên sử dụng bóng đèn năng lượng thấp trong ngôi nhà của mình. Nó sẽ giúp chúng tôi giảm hóa đơn tiền điện. Thứ hai, trước khi đi ngủ, chúng ta nên tắt các thiết bị điện khi không sử dụng. Cuối cùng, chúng ta nên tắt đèn trong phòng khi ra ngoài, tránh lãng phí nước, tắt bếp khi ngừng nấu.
1 Now, there are many different transport : truck, car, ..... But I love bicycle best. Because it doesn't need fuel , it is small and simple. Although it makes everyone be tired however cycle is a good activities . We are better if we cycle . But it loads a little merchandise so people use it a little .
- 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.
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?
=> You should: use electricity more efficiently
turn of the lights when we aren't using them
use low energy light bulbs
use public transport
Nowadays, energy is being run out more and more so it is one of the most important things of our life. We need to save energy because nobody of us can lives without energy. So why don't we start to do it right in our home? We have many ways to save energy in our home. One of those ways is using electricity, water and gas economically. Such as we should turn off the light in room when we go out or in unnecessary situations, avoid wasting water, shut the kitchen stove when stop cooking. Use a microwave instead of a stove to reheat food. Use rechargeable batteries instead of disposable batteries... Besides, we should use electrical equipments which are energy - saving. Such as using lights and fans that have low capacity, or using equipments which reserve electricty. Not only do these help us to save money but also they work effectively.
In addition, we should frequently check electrical equipments in our home in order to fix opportunely. In summary, we need to save energy so that energy isn't run out and continues to serve human's life.
2. Write about one types of alternative source energy.
Solar, light and heat radiation from the sun, has been exploited by humans since ancient times using a growing array of technologies than ever before. Solar radiation, along with secondary resources of solar energy such as wind and wave power, water and biomass, make up most of the renewable energy available on Earth. Only a very small fraction of the available solar power is used.
Solar power means generating electricity based on heat and photovoltaic cells. The use of solar energy is limited only by human ingenuity. Partial list of solar applications space heating and cooling through solar architecture, through distillation of drinking water and sterilization, daylight illumination, solar hot water , Solar cooking, and high temperature process heat for industrial purposes. To collect solar energy, the most common way is to use solar panels.
Solar technology is widely described as either passive solar or active solar energy depending on how they capture, convert and distribute solar energy. Active solar engineering involves the use of photovoltaic panels and solar thermal power to harness the power. Passive solar engineering involves orienting a building towards the sun, selecting materials with favorable heat mass or dispersed light property, and designing natural air space.
There are many ways to save energy.
Firstly, you should turn off the lights before going to bed or going out. You should use low energy light bubls or reduce our electricity bills. Secondly, you can also use public transport instead of cars, motorbikes, ... and we should increase the tax on petrol so that people use less petrol. It makes the air will be fresher and less toxic fume. Besides, you should reduce the use of fossil fuels and use other alternative sources of energy. Moreover, you should avoid using cars or motorbikes for short distance so you can save energy.
To sum up, saving energy is very good for us and our environment. Using less electricity, using energy saving light bubls and using public transport are three main ways to prevent our energy from being limited.
