+ 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

Solar, light and heat radiation from the sun, has been exploited by humans since ancient times using a growing array of technologies than ever before. Solar radiation, along with secondary resources of solar energy such as wind and wave power, water and biomass, make up most of the renewable energy available on Earth. Only a very small fraction of the available solar power is used.
Solar power means generating electricity based on heat and photovoltaic cells. The use of solar energy is limited only by human ingenuity. Partial list of solar applications space heating and cooling through solar architecture, through distillation of drinking water and sterilization, daylight illumination, solar hot water , Solar cooking, and high temperature process heat for industrial purposes. To collect solar energy, the most common way is to use solar panels.
Solar technology is widely described as either passive solar or active solar energy depending on how they capture, convert and distribute solar energy. Active solar engineering involves the use of photovoltaic panels and solar thermal power to harness the power. Passive solar engineering involves orienting a building towards the sun, selecting materials with favorable heat mass or dispersed light property, and designing natural air space.
It is Solar-energy plane. It looks a normal plane but it has the solar panel on the wings. The panel will catch the sun shine and create the electricity for the plane. It maybe a great invention helping to create the energy and protect environment.

My first visit to Nha Trang, the coastal city, was three years ago. It was a pleasant and memorable trip.
Nha trang, the capital of Khanh Hoa province, has one of the most popular municipal beaches in all of Viet nam. In Nha Trang, nature beauties are so tempting. Waves crashing onto the cliffs, the soft sigh of the sea breeze, clean white sands and turquoise waters, it all makes for a stunning landscape. On my visit to Nha Trang, I used to get up early each morning to stroll along the beach - a chance to breath in the fresh sea air and enjoy the sunrise across the water. One attraction that captivated me three years ago and still it does is the collection of small offshore islands, that is Hon Tre where is the largest of the islands.
Nha Trang is the city in hamoney, its fine wather, favorite position and friendly people bring it a certain balance. Nha Trang is a great holiday destination. I hope to have chance to come back
