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.

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.

We need energy to live and work. Our major source of energy is oil. Oil is one kind of fossil fuel. The amount ot fossil fuels in the world is limited. Therefore, we must save it, and at the same time, we must find new sources of energy. Geothermal heat and nuclear power are alternative sources of energy. They can give us electricity. Other alternative sources are the sun, waves and water. These sources are not only unlimited and available but also clean and safe for the environment. People should develop and use them more and more in the future.

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure.
Coal gasification can be used to produce syngas, a mixture of carbon monoxide (CO) and hydrogen (H2) gas. . The use of coal as fuel causes adverse health impacts and deaths. Coal mining and coal fueling of power station and industrial processes can cause major environmental damage.

There are many types of natural disasters, storms are one of them, a storm is a turbulent state in the atmosphere and a type of extreme weather.There are many types of storms: Snowstorms: a very heavy snow phenomenon. thick with strong winds. Usually occurs in cold or temperate countries. Sand tornado: also known as sand demon, is a phenomenon of sand swept up very high, occurring at noon in desert areas. To: is the phenomenon of wind speeding up suddenly, accompanied by strong thunderstorms. Thunderstorms: are storms accompanied by thunder, heavy rain or hail. Tornado: is a phenomenon of a circular swirling air stream extending from a thunderstorm cloud down to the ground, especially in that a thunderstorm can descend on empty fields (rural areas) and cities. Fire storm: is a way to call intense fires that have created their own convection system and wind, making it extremely large and difficult to control or extinguish. Tropical cyclones are rapidly rotating storm systems characterized by a center of low pressure, strong winds and a spiral cloud structure that produces heavy rain. lots of homes. The bigger the storm, the more loss of life and property. Storms often break trees and damage homes. A hurricane with a tornado can sweep people and houses away, break trees, cause crop damage, and cause accidents to planes and boats. Therefore, we must take timely measures to prevent storms, we must resist our house carefully, so we can prevent a little hảm from storm.

Flood is considered as one of the most dangerous disasters in the world. There was a “historical flood” that happened in Hanoi in 2008. This must be a year that Hanoians can never forget because the rain was so heavy and lasted for many days consecutively that inundated many streets of Hanoi. The rain was considered heaviest in the last 100 years, which caused people to suffer from a lot of damage. According to statistics, many families even suffered from inundation as high level of water flew into their houses. Offices or schools had to make emergency announcement to let their employees and students be at home to avoid any potential accidents that may caused by the pouring rain. Life then had a lot of disturbance and people had to wait until it stopped raining. The rain triggered inconvenience for people in different fields as high death toll was recorded, traffic was in no order or people stood a high chance of dangerous epidemics. Luckily, after a few days, life began to come back to the way it was thanks to concerted effort of both local authority and many people of the city.

Paragraph:
The Earth is gradually running out of resources. Resources are scarce day by day, so scientists are researching and looking for new resources. In temperate countries, due to have many the wind, the wind is used to generate electricity. In tropical countries, due to having much sunshine, the sunshine is used to generate electricity. And a lot of countries in the world use different resources instead of using water to generate electricity.
Traslate:
Trái đất đang dần cạn kiệt tài nguyên. Nguồn tài nguyên khan hiếm từng ngày, vì vậy các nhà khoa học đang nghiên cứu và tìm kiếm những nguồn tài nguyên mới. Ở các nước ôn đới, do có nhiều gió nên gió được dùng để sản xuất điện. Ở các nước nhiệt đới, do có nhiều ánh nắng mặt trời nên ánh nắng mặt trời được sử dụng để phát điện. Và có rất nhiều quốc gia trên thế giới sử dụng các nguồn tài nguyên khác nhau thay vì chỉ sử dụng nước để tạo ra điện.

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.

In the environment have a lot of sources of energy, especially natural and nuclear power, two completely opposite energies. Natural gas are cheap but we have to use them in the most effective way and of course it does not pollution the anvironment. And nuclear power are expensive, we should not use it if you want life longer because it very dangerous. There are two power in the world, one side is safe, cheap and one side is expensive, dangerous
