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.
- What you should do to save energy
There are some tips to save power which I think are very easy to apply. Firstly, we should use energy saving light bulbs in our house. It will help us to reduce our electricity bill. Secondly, we should use public transport if we need to go long distance. We can use bicycles for short distances. I think it is good for our health and economical. And remember, before going to bed, we should turn off all lights and other unused electrical devices. It's an easy way to save our planet.
Talk about the advantages and disadvantages of renewable sources of energy and non-renewable sources of energy
( Mn viết thành bài văn hộ ad nha )
Renewable energy describes a collection of energy technologies i.e. solar, wind, geothermal derived from sources that are never-ending and can be replenished time after time. Most countries across the world heavily depend on fossil fuels (oil, coal andnatural gas) as sources of energy to power their economies.
Fossil fuels are non-renewable forms of energy, meaning, they utilize limited resources that will ultimately deplete, hence, driving up overall energy costs. These very countries have responded to the threat by stepping up campaigns to embrace renewable forms of energy like solar and wind
Talk about the advantages and disadvantages of sources of energy you know.
- What kind of the sources of energy? ( renewable or non - renewable)
- What are the advantages/ disadvantages of the sources of energy?
- What do you think people will use it more in the future?
rewable:wind,solar enery,hydro,nuclear,biogas...
non rewable:coal,oil,natural gas...i think people will use it more in the future

In Vietnam there are a lot of traffic problems in my country. First, there are too many people using the roads in the rush hour. Second, there are too many vehicles on the road that leads to traffic jams. Another problem is that many roads are narrow and bumpy. Fourth, there are traffic accidents every day so a lot of people are injured. I think we should obey the traffic rules and traffic signs as well.

talk about the advantages and disadvantages of renewable sources of energy.
Renewable energy comes from a source that will not deplete. Two common examples of this type of energy are solar power and wind power. Geothermal power, hydropower, biomass, and tidal power are additional forms of renewable energy that produce power for our planet right now.
The primary advantage of renewable energy is that fewer potentially harmful emissions are released into the atmosphere. Although fossil fuels are used to create the products that allow for this power to be produced, most forms of renewable energy can become carbon neutral in 5 years or less.
The disadvantage of renewable energy is that it can be costly. Although wind power and solar power have become cost-competitive with coal-fired power and nuclear power in some communities, some forms are not cost-competitive globally yet when the cost per kilowatt hour is compared. In 2015, the lifetime cost per kilowatt hour of conventional coal was 9.5 cents, while the cost of offshore wind was 15.8 cents.
There are additional advantages and disadvantages of renewable energy to consider as well.

Short Article on “Alternative Energy Sources” The rapid increase in the demand of energy has caused worry about its supply. The main sources of energy are conventional sources. They are non-renewable and exhaustible sources. : The demand of energy has increased all over the world and the condition poses a threat on the sources of energy like Petroleum and Natural gas by the year 2030-35 if any alternative sources do not substitute or supplement them. The Government of India gives high priority to the use of alternative, non-conventional and renewable energy sources as supplement to the depleting conventional sources of energy. These alternative sources include – Solar energy, Wind energy, Geo-thermal energy, Tidal energy, Biomass energy etc. These energy sources have huge potential of energy and they can be useful in various ways. Solar energy is a wide source. Solar cells, solar cookers, solar ponds etc are the devices to trap solar energy. It can produce electricity, cook food, heat water and can be converted to other forms of energy. The solar photovoltaic system which uses solar cells to convert the solar energy into electrical energy is the most promising and progressive sources of alternative energy. Wind energy is in form of Kinetic Energy. A blade of windmill is moved by blowing winds and could be exploited for doing work. Theoretically about 60% of the wind energy can be converted into other forms of energy. Wind mill farms are being set up in the world to exploit this energy at suitable places. Geothermal energy can be used to produce electricity. However, the inner heat of the Earth not available everywhere which can be commercially exploited. Such potential has been found in Pegu valley in Jammu and Kashmir in India. Tidal energy associated with the kinetic energy of tides can be converted into electricity by using turbine. In the coastal areas this possibility is available. Biomass energy is being used in villages but improvement in method and scientific equipments can increase utilisation. It reduces waste materials and gives cheap energy. Jathropa is a plant that produces diesel and it is pollution free. Besides the railways lines, Jathropa planting is in implementation. Hydrogen is also proved to be a great advantageous source of energy. Nowadays, nuclear energy is gaining utmost importance. These alternative sources of energy promise a new horizon in sustainable manner.
