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 Environment

Solar 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 Bill

Generating 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 Demand

Energy 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 Everywhere

As 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 Security

The 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 Creation

Large 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.

I think it is desirable for secondary school students to wear casual clothes when they are at school.

Firstly, casual clothes make all students feel comfortable. They don't feel constrainted to wear uniform that they don not like.

Secondly, for one thing, casual clothes can also give students freedom of choice. They can choose what sizes, colors, and fashions of clothing they love. And for the other, parents do not worry about their clothes because their children can wear any clothing to school as long as it is clean and tidy. It can be said it is the positive aspect for the poor people in the present difficult economic condition.

Finally, casual clothes can make students feel self-confident when they are in their favorite clothes. And what's more it makes the school more colorful and lively.

In conclusion, in my opinion, all the secondary school students should wear casual clothes.

Unlike in the old days, we could only learn English through radio books, television and in school. There are many more ways to learn English today, especially through the internet, smartphones and many English learning centers opened up. There is no compulsory method to learn English, but each person must find a suitable way to learn it effectively. Many people will think that learning English is difficult, but what we need to do is get our own way of learning and an effort. Using the right vocabulary and sentence structure correctly requires a long process, but we can always invent new learning methods. We can go to parks or join English-speaking clubs for a chance to speak with foreigners, and that helps us improve our grammar and accent. Books, movies, songs, and newspapers in English are also what help us get used to how foreigners use it. The key to learning English is that we should not try to remember everything in the notebook, but we need to meet and practice it in real life. But learning English can be more effective when we can create our own learning styles.

Favourite kind of music:

Most people like music and so do I. I like music because it is my favourite entertainment in my free time. Moreover, music is good for my spiritual relaxation and helps release my work-related stress. My favourite music genre/style is POP due to four reasons.
Firstly, I am most spiritually relaxed by listening to POP music as it makes me feel excited and comfortable. For this reason, I listen to it every afternoon.
Secondly, it makes me more positive and active so that I can do my works better.
Thirdly, by sharing the common interest in POP music, I can make a lot of fiends around the worlds without the need of speaking their own language.
Finally, I believe that listening to POP music makes me smarter in my daily activities.
Different people have different taste in music but I think POP music is the most popular and has the largest number of fans. In America, Taylor Swift is the top POP singers with thousands of followers including me. Nevertheless, there are so many kinds of music in this world and I believe all of them are good in bringing people closer and making people love their lives even more.
