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

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

As you know, energy is very important for our lives. We need energy to live and to work. If there isn’t energy, our lives will be very difficult. However, the natural resources are being used up. So we should know how to save energy in the three following ways: First: how to save water. Second: how to save electricity. Third: how to save petrol or gas.

As for me, we should save water by taking a shower instead of a bath; using less hydro. We should save electricity by turning off the lights, TV, air conditioner,…before leaving the room; using low energy light bulbs. To save petrol or gas, we should use public transport for short trips; try walking or cycling instead of using cars or motorbikes; using less gas when cooking. To sum up, we should save energy because to save is also to money as to as natural resources.

Như bạn đã biết, năng lượng rất quan trọng đối với cuộc sống của chúng ta. Chúng ta cần năng lượng để sống và làm việc. Nếu không có nghị lực, cuộc sống của chúng ta sẽ rất khó khăn. Tuy nhiên, các nguồn tài nguyên thiên nhiên đang được sử dụng hết. Vì vậy chúng ta nên biết cách tiết kiệm năng lượng theo 3 cách sau: Thứ nhất: làm thế nào để tiết kiệm nước. Thứ hai: làm thế nào để tiết kiệm điện. Thứ ba: làm thế nào để tiết kiệm xăng hoặc khí đốt.

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.

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.

We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable.

Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution.

On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like nonrenewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the winds blow throughout the year. The five types include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, energy from moving water; biomass, energy from dead plants and microorganisms and finally, energy from the wind.
