We are now facing the excessively increasing consumption of energy all over the world. It is predicted that global energy consumption will rise nearly sixty percent in the next twenty years. This rise is caused by some factors such as population growth, urbanization, and economic and industrial expansion.
Seeking cheap, clean, effective sources of power, some countries are hopeful of being able to produce part of their electricity with renewable means such as wind or solar power. On a cloudy day in Britain, a solar roof can generate enough electricity for the household to play 140 hours of TV and make 35 cups of tea. One kilowatt of solar energy can save up to a ton of CO2 emissions each year. Solar panels and wind generators help to provide alternative sources of energy for private homes, and they are no longer too expensive. These renewable energy systems can lead to big savings for households in the long run and in Britain the government is providing financial help with the cost of installing them.
In addition to the use of renewable energy sources, human beings now know how to save energy more efficiently. Companies make electrical equipment which is environment-friendly and money-saving. Refrigerators, washing machines, tumble dryers and other home appliances are labeled to help consumers compare the energy efficiency of each model with other appliances in the same category. Households also try to save energy in whatever way. Ordinary light bulbs are replaced with energy-saving bulbs. Having a shower instead of a bath becomes more common. TVs, electric fans and air conditioners are turned off when they are not in use. Those are simple actions but they contribute significantly to the energy saving movement.
In a nutshell, using renewable energy sources and saving energy at home not only saves money but also protects the Earth’s resources.

Good morning, everyone! My name is Ha Chi and today I’m going to give you some useful information about how to save water at home .Well, we all know that water is an integral part of our life; thus, we cannot stop using it but just reduce the amount of water we use daily. These following tips will help us to cut down on water waste.
Firstly, we should regularly check faucets, pipes and toilets for cracks to ensure that any leaking toilet tanks or dropping taps are fixed as soon as possible. Secondly, don’t forget to turn off the taps while we are brushing our teeth, washing our face or getting a shave as we can save up to 5 liters of water per minute. Thirdly, having a shower uses much less water than bathing in a bathtub, so try to take a shower every time you can. Another tip is to run washing machines and dishwashers only when we have enough dirty clothes and dishes for full loads. Lastly, never think of using the toilet as an ashtray or a wastebasket for cigarette butts, facial tissues, tea bags and other kinds of small trash because flushing these items can waste about ten liters of water each time . It can be concluded that these five simple actions help us save water, save our own money and prevent water pollution as well. Thanks for your listening!

Chào buổi sáng mọi người! Tôi tên Hà Chi và hôm nay tớ sẽ cung cấp cho bạn một số thông tin hữu ích về làm thế nào để tiết kiệm nước ở nhà. Vâng, chúng ta đều biết rằng nước là một phần không thể tách rời của cuộc sống của chúng tớ; Do đó, chúng ta không thể ngừng sử dụng nó mà chỉ làm giảm lượng nước mà chúng ta sử dụng hàng ngày. Những lời khuyên dưới đây sẽ giúp chúng ta giảm được lượng nước thải.
Thứ nhất, chúng ta nên thường xuyên kiểm tra các vòi nước, đường ống và nhà vệ sinh để đảm bảo rằng các thùng chứa vệ sinh rò rỉ hoặc vòi nước được cố định càng sớm càng tốt. Thứ hai, đừng quên tắt vòi nước trong khi chúng tôi đang đánh răng, rửa mặt hoặc cạo râu vì chúng ta có thể tiết kiệm đến 5 lít nước mỗi phút. Thứ ba, tắm vòi sen sử dụng ít nước hơn tắm trong bồn tắm, vì vậy hãy cố gắng tắm mỗi lần bạn có thể. Một gợi ý khác là chạy các máy giặt và máy rửa chén chỉ khi chúng ta có đủ quần áo bẩn và các món ăn để tải đầy đủ. Cuối cùng, đừng bao giờ nghĩ đến việc sử dụng nhà vệ sinh như một cái gạt tàn hoặc một cái thùng đựng phế liệu, khăn mặt, túi trà và các loại rác nhỏ khác vì việc xối rửa những đồ này có thể tốn khoảng 10 lít nước mỗi lần. Có thể kết luận rằng năm hành động đơn giản này giúp chúng ta tiết kiệm nước, tiết kiệm tiền của mình và ngăn ngừa ô nhiễm nguồn nước. Cảm ơn các bạn đã lắng nghe!

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.
