Hello everyone, today I'd like to tell you some information about types and sources of energy. Energy is classified into two main groups: renewable and non-renewable.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. 2. 1. Use public mode of transportation
Encourage people to use more and more public modes of transportation to reduce pollution. Also, try to make use of carpooling. If you and your colleagues come from the same locality and have same timings you can explore this option to save energy and money.
2. Conserve energySwitch off fans and lights when you are going out. A large number of fossil fuels are burnt to produce electricity. You can save the environment from degradation by reducing the number of fossil fuels to be burned.
3. Understand the concept of Reduce, Reuse and RecycleDo not throw away items that are of no use to you. In-fact reuse them for some other purpose. For e.g. you can use old jars to store cereals or pulses.
4. Emphasis on clean energy resourcesClean energy technologies like solar, wind and geothermal are on high these days. Governments of various countries have been providing grants to consumers who are interested in installing solar panels for their home. This will go a long way to curb air pollution.
5. Use energy efficient devicesCFL lights consume less electricity as against their counterparts. They live longer, consume less electricity, lower electricity bills and also help you to reduce pollution by consuming less energy.
Several attempts are being made worldwide on a personal, industrial and governmental levels to curb the intensity at which air pollution is rising and regain a balance as far as the proportions of the foundation gases are concerned. This is a direct attempt at slacking Global warming. We are seeing a series of innovations and experiments aimed at alternate and unconventional options to reduce pollutants. Air pollution is one of the larger mirrors of man’s follies, and a challenge we need to overcome to see a tomorrow.
3.TYPE OF NATURAL DISATER: Flood
WAYS TO PREPARE:
• – Check for local flood warnings if your area is at risk: look online or call Floodline.
• – Tune in to the local radio or television news for updates. Alert your neighbours, particularly elderly or vulnerable people.
• – Prepare an emergency kit, including emergency numbers, insurance policy, first aid kit, torch and water.
• – Use our home emergency contacts sheet so you have the numbers you need to hand, even if you lose power.
• – Have a list of irreplaceable items to keep safe and put important personal documents into a sealed bag.
• – Pack essential items you will need if evacuated – medication, clothing, toiletries and items for children.
• – Purchase unfilled sandbags and sand from builders’ merchants. Remember that, if there is a flood, demand may exceed supply – as people will rush to buy them.
• – Empty freezers and refrigerators, leaving doors open.
• – If you can, move any vehicles to higher levels.
• – If you have time, take photographs before you leave. This may help later with insurance claims.
• – Turn off the mains power and water, and take mobile phones and chargers with you. Put sandbags in toilet bowls to prevent sewage back-flow.
• – Shut windows, lock doors – and don’t forget to take your pets.

Saving energy is very important but it's also easy. First, we can use low energy light bulbs in our house, our classroom. We can turn off the light when we don't use. Next, we can use biogas to cooking. We can use hand fan instead of using electric fan. Finally, we shouldn't use private cars to traveling

Nowadays, energy is being ran out more and more. We need to save energy because nobody of us can lives without energy. So why don't we start dong 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.
Besides, we should use electrical equipments which is energy - saving. Such as using lights and pans that have low capacity, or using equipments which reserve electricty. Not only 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 sammary, we need to save energy so that energy isn't ran out and continues to serve human's life.

1.Save energy at home:
Energy is very important in human life so we need to save energy.If we go on wasting energy, they will quickly run out.There are some ways to save energy at home. We should use shower heads (bỏ short đi vì có lẽ nó k nên ở đây) or buy" low-flow" showerheads/shower faucets (Thêm từ) and use fewer baths (baths số nhiều).Turn off the lights and air conditioners before you leave home, rooms.We also should keep the refrigerator doors closed and go to school by bike (Có vẻ k liên quan?).It's very easy to save energy at home.If we follow these tips ( ghi cụ thể), we can save energy and save our life.

2.Future mean of transport:
I think in the future, driveless car will be the most popular ( K có đối tượng thứ 2). The driverless car just looks like an odinary car.It will use ( Bỏ Be đi - không phù hợp) solar energy to operate so it runs very fast.People can use it on the ground and it can transport 4 people.This driverless car will bring a lot of benefits.You can work or even sleep while it is driving ( Nên dùng HTTD vì có while ở trước) itself by using sensors and camera systems.Elderly and disabled people are able to drive it.I like this driverless car very much.
Một số chỗ bài này bạn đã copy của trang nào phải không. Dù đúng hay không, biết vận dụng là tốt. Mình đã từng đọc qua 1 bài gần như này :]

Ngày nay,năng lượng ngày càng giảm sút rất nhiều vì vậy nó là 1 trong những thứ quan trọng trong cuộc sống của chúng ta.Chúng ta cần tiết kiệm năng lượng vì ko ai trong chúng ta có thể sống mà ko có nó.Và có rất nhiều cách để tiết kiệm năng lượng
Đầu tiên,chúng ta nên sử dụng điện hiệu quả hơn.Chúng ta nên tắt điện,tivi và các thiết bị điện khác khi chúng ta ko sử dụng chúng.Chúng ta có thể sử dụng bóng đèn tròn để tiết kiệm điện.Thứ 2, chúng ta nên sử dụng ít phương tiện cá nhân hơn.Chúng ta nên đi bộ hoặc đi xe đạp khi di chuyển 1 quãng ngắn hoặc sử dụng phương tiện công cộng khi di chuyển quãng dài.Hơn nữa,chúng ta nên đóng cửa tủ lạnh sau khi sử dụng nó.Chúng ta cũng có thể sử dụng quạt tay hoặc mở cửa sổ để làm mát vào mùa hè.Cuối cùng,chúng ta nên giảm lượng nước mà chúng ta sử dụng.Tắm bằng vòi hoa sen thay vì bằng bồn là 1 cách tốt.Bên cạnh,chúng ta cũng nên đóng vòi nước khi đánh răng
Tóm lại, những cách trên có thể cứu cuộc sống của chúng ta trong tương lai vì vậy chúng ta hãy nâng cao ý thức về việc tiết kiệm năng lượng
