*) Talk about ways to save energy:
As you know, our energy has limitation, so we must save energy because of the following ways. Firstly, we have to turn off the electric appliances when we do not use them. Secondly, by using bicycle or public transports instead of motorbikes or cars. Finally, we should not throw all used papers and bottles. I suggest collecting them to reuse and recycle. Therefore, if we follow the above ways, we will not only save money but also conserve the energy.

Talk about the main of transport in the future:
I believe that in 20 years the cars we drive will not be that different. I think most of the cars will move away from traditional fuel sources, but for the most part, will remain unchanged. I think the biggest problem we face isn't changing the vehicle itself, but the infrastructure that it depends on. I believe in the next century we will see a change in the road systems which will allow for greater density of vehicles, reducing the amount of space needed for roads and highways. Americans want a vehicle that can go anywhere, off road, on a race track, or down the freeway, and I believe in the future we will have multiple cars for different uses. One car for cruising around town, probably a fully electric vehicle, and another for commuting and urban driving. For those who still crave a little dirt under their tires, I think there will always be traditional Jeeps, trucks, etc. We will always have a large need for construction equipment, and I don't see those vehicles changing, other than by converting to cleaner fuels. I also believe that before 2050, self-driving cars will be coming on the market. If a 'track' system, or some system of guidance were implemented on major thoroughfares and in urban areas, a commuter could simply pull onto the freeway and switch to autopilot. This would allow cars to flow in a much more organized fashion, allowing higher speeds, safer roads, and fewer emissions caused by road congestion. The other thing I see increasing is the use of air travel. If aircraft could be made easy enough to fly by the average Joe, with a licensing system equivalent to the DMV, I believe more people would travel by air. Whatever happens, I believe or streets will be safer to drive on, and our cars will be more fun to ride in.

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.

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.

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.

Good morning/afternoon ladies and gentlemen,
My name is Dang. Today I’m going to tell you how to save home energy.
Most people use too much electricity and water at home. You can reduce the amount of energy by
-using short shower heads or buy ’low-flow’ showers;
-turning off the lights and air conditioners before leaving home or whenever you are not in your rooms.
-keeping the refrigerator doors closed.
-going to school by bike.
If you take my advice, you won’t have to pay so much for your bills, and you can save necessary energy.
Thanks for listening.
