Solar energy brings us both benefits and drawbacks. One of the biggest advantages is that it is a renewable energy source. Energy can be produced as the sun lasts forever. Therefore, solar energy can really be called as a long- term energy source. Furthermore, that is a non- energy source of pollutants such as zero carbon dioxide or other gases in electricity generation. Beside those benefits, solar energy also has some drawbacks. The initial installation cost of solar cells is quite high, so not all people can use it. Also, it can not effectively work in cold weather due to the scarcity of sunlight. In conclusion, we can't deny the advantages of solar energy, but it still exists some disadvantages.

Thứ 3, thay vì đi ô tô hay xe máy, chúng ta có thể đi bộ đi học hoặc đi làm. Bằng những cách này, chúng ta có thể tiết kiệm được rất nhiều năng lượng.
Advantages of renewable energy
The first advantage of renewable energy is that it can be renewable, has an extremely large reserve, can be endless. Forms of energy such as solar, wind, geothermal, ocean waves, rain... are available and free to use, without fuel costs. Biomass energy also has large reserves and low fuel costs. Compared to traditional energy sources such as coal, oil, natural gas, which are increasingly depleted, only meeting human energy needs for about 50-70 years, this advantage is a strength. outstanding.
The second advantage of renewable energy is that it is abundant and can be widely exploited in all different areas of the earth. For example, with solar energy, people can exploit it anywhere, as long as there is sunlight, it can be used to generate heat to make hot water, heating, and generating electricity through the system. Solar power with solar panels… Or with wind energy, this energy source has been used for hundreds of years to move sailing boats, hot air balloons, windmills for irrigation systems. … or the current trend is to produce electricity from wind in many countries around the world.
Despite many great advantages, renewable energy also has some disadvantages, such as:
Due to the influence of nature, renewable energy is less stable than traditional energy sources. Solar energy can only be exploited during the day on sunny days, and at night or on cloudy and rainy days, the system will not work. Or with wind energy, wind turbines can only generate electricity at times when the wind speed is in the range of 4-25 m/s. Wind speed must be at least 4 m/s for the wind turbines to start running smoothly and generate electricity, but if it exceeds 25 m/s, the turbines will stop working to avoid damage in windy conditions. strong.
Requires advanced technology and high cost is also a drawback of renewable energy. To take advantage of renewable energy sources to generate electricity, it requires advanced technology and relatively high investment costs. Currently, the cost of electricity generation from renewable energy is generally higher than the cost from fossil energy. However, the development of renewable energy in the global trend has helped to reduce costs and increase efficiency, gradually improving this shortcoming.

+ Advantages of solar energy:
One of the biggest advantages of solar energy is that it is a renewable energy source. Energy can be produced as long as the sun lasts, which is millions of years. Therefore, solar energy can really be called as a long-term energy source.
-As direct electricity develops from solar energy, there is no scarcity of raw materials, i, sunshine. It is found in abundance.
-The solar cells are very easy to install, can be installed on the roof and so no extra space is needed. Generation of energy at a small scale, on the basis of individual users
-The solar panels are not noisy and stationary. They also require very little maintenance.
-Solar energy can be produced in any part of the world, in any place where more sunlight is available.
One of the most important environmental advantages of solar energy is that it is a non-energy source of pollutants such as zero carbon dioxide or other gases in electricity generation.
Due to the above reasons, solar energy is not dangerous to the environment and therefore, is also known as a clean energy source.
When thinking about the economic advantages of solar power, then one should note that in addition to the initial installation costs, solar generation and use is free. No charge, the bill to tend to!
- Coal, natural gas and petroleum and other fossil fuels tend to increase continuously. Solar, on the other hand, is free.
-Solar energy can be used to cook, heat water, and also to operate various electrical appliances based at home or office.
- Finally, one of the other major benefits of solar power is that this renewable energy is healthier, safer and easier to use at home, on the office or on a large scale.
-Now you know what are the advantages of solar power, you have to wonder is there any difficulty or defect of solar energy? Then the answer is yes, there are some negative aspects of the source of energy. Tell us more about it.
+ Disadvantages of solar energy
-The initial installation cost of solar cells is quite high. However, a need to invest only in installation and then electricity is free.
-Solar energy can not effectively work in cold water due to the scarcity of sunlight.
-For large-scale applications, larger area and higher investment is needed, which can not be met easily.
Solar energy makes us have solar electricity, light to live. If you don't have solar energy, you will have to use electricity, but using electricity will cause a fire, so solar energy is very good

Although it seems that every generation has its own favorite types, I think the passion for music is always maintained over time. I also like listening to music, and I listen to the music of many singers from all around the world. Although sometimes I cannot totally understand the meaning of foreign lyrics, I still feel the soul of the songs through the melodies. Music for me is just like feelings of human because there are always happy, sad or complicated songs that reflect the mood of the composers. Music has been around us for thousands of years as a form of entertainment for human, and I think there will be more and more genres to meet the demand of people.
