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. Ỉ 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
- Solar energy is a clean and renewable energy source.
- Once a solar panel is installed, solar energy can be produced free of charge.
- Solar energy will last forever whereas it is estimated that the world’s oil reserves will last for 30 to 40 years.
- Solar energy causes no pollution.
- Solar cells make absolutely no noise at all. On the other hand, the giant machines utilized for pumping oil are extremely noisy and therefore very impractical.
- Very little maintenance is needed to keep solar cells running. There are no moving parts in a solar cell which makes it impossible to really damage them.
- In the long term, there can be a high return on investment due to the amount of free energy a solar panel can produce, it is estimated that the average household will see 50% of their energy coming in from solar panels.
Disadvantages of Solar Power?
- Solar panels can be expensive to install resulting in a time-lag of many years for savings on energy bills to match initial investments.
- Electricity generation depends entirely on a countries exposure to sunlight; this could be limited by a countries climate.
- Solar power stations do not match the power output of similar sized conventional power stations; they can also be very expensive to build.
- Solar power is used to charge batteries so that solar powered devices can be used at night. The batteries can often be large and heavy, taking up space and needing to be replaced from time to time.
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.Tet is a national and family festival. It is an occasion for every Vietnamese to have a good time while thinking about the last year and the next year. At Tet, spring fairs are organized, streets and public buildings are brightly decorated and almost all shops are crowded with people shopping for Tet. At home, every is tidied, special food is cooked,offerings of food, fresh water, flowers and betel are made on the family altar with burning joss- sticks scenting the air. First-footing is made when the lucky visitor comes and children are given lucky money wrapped in a red tiny envelope. Tet is also a time for peace and love. During Tet, children often behave well and friends, relatives and neighbors give each other best wishes for the new year.
2.Environment is an essential part of our life. A clean environment is necessary for a peaceful and healthy life. An environment is the natural surroundings which helps human beings, animals and other living things to grow and develop naturally. But nowadays, our environment is disturbing in many different ways. Any type of disturbance in the nature’s balance affects the environment totally. It does not only ruin human lives but also affects on all living beings. We can save our environment with the little step taken by everyone on the earth. We should reduce the amount of waste, throwing wastes properly to its place only…and many other simple ways. It is very important to save environment for human existence. When we protect the environment, we are protecting ourselves and our future as well.

Solar energy is obtained from the sun’s radiation and it can be converted to electricity or heat. It is freely available and thanks to advances in technology, we can now harness even more of the solar energy that is continuously available to us. Here are 7 benefits related to this renewable source of energy.
1.Impact on the EnvironmentSolar energy has the least negative impact on the environment compared to any other energy source. It does not produce greenhouse gases and does not pollute the water. It also requires very little water for its maintenance, unlike nuclear power plants for example, needing 20 times more water. Solar energy production does not create any noise, which is major benefit, since a lot of solar installations are in urban areas.
2.Reduce Your Energy BillGenerating your own electricity means that you will be using less from the utility supplier. This will immediately translate to savings on your energy bill. Plus, you can also make money by selling the unused electricity, which you have generated, back to the grid. The more energy you produce, the less you will need from the supplier which will increase your energy self reliance.
3.Energy Production Matches the Time Frame of Higher DemandEnergy needs tend to be higher in the 11:00-16:00 time frame and then early in the evening. Naturally, this is the period when the price of the electricity peaks. Solar energy happens to reach its maximum production capacity during those hours. Electricity produced at that time has higher value than if it was generated at night. With the additional electricity input of solar energy, prices in those time frames could be driven down to a level close to those of night hours.
4.Solar Energy Is Applicable EverywhereAs long as there is sunshine, solar energy can be deployed anywhere. This is particularly useful for remote regions with no access to any other source of electricity. There is a vast amount of people around the world with no access to electricity. Independent solar systems could be deployed in those regions and improve the lives of millions of people. Moreover, solar energy is also used to power up spacecrafts and boats.
5.Less Electricity Lost During Long-Distance Transport.Some of the energy, around 3-5%, is lost during transportation and distribution. The longer the distances between the production and the supply points, the more energy is lost. Those loses might not seem significant but they can influence the performance of the installation in regions with high population density. Having solar panels on the roof or in the yard significantly reduces this distance, therefore increasing the efficiency of the electrical system.
6.Improves Grid SecurityThe grid is less vulnerable to blackouts if there are many power plants which are spread out. A grid with high penetration of solar energy has thousands of energy production centres which are widely spread out. This improves the security of the grid in case of overload, natural or human-caused disasters.
7.Job CreationLarge part of the cost associated with solar systems comes from the installation of the panels. This contributes to local job creation. Using solar systems boosts the economy and positively affects the local community.
