Cho bạn nào có câu hỏi giống mình mà vẫn chưa tìm được câu trả lời. 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.
To meet the challenge, various methods have been suggested. One is to minimize the man’s demand in using the energy. Non-essential consumption should be minimized. During certain days of the year, people all over the world turn off the electricity for 1 hour to save the energy. Modern gadgets consuming energy should only be used when they are absolutely necessary.
Energy conservation is possible through modernization of plant and equipment. People should replace the obsolete equipment by the modern ones.
Energy can be saved on transport by the following methods. People should commute by the rail rather than by cars and vans. The transport must be improved with a view to sparing the energy. Cities must be planned in such a way that the commuting distance from this place to others is minimized.
In industry, many things could be done to reduce waste of energy or to economize energy. The machine maintenance needs to be tightened; heater must be utilized properly. When systems are streamlined, economy in fuel is obvious. Instead of using materials requiring higher energy, those which require lower energy should be used.
We hope man with his ever rising urge for existence will cope up with this urgent problem and find alternatives.

+ 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.

Nowadays, energy is being run out more and more so it is one of the most important things of our life. We need to save energy because nobody of us can lives without energy. So why don't we start to do 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. Use a microwave instead of a stove to reheat food. Use rechargeable batteries instead of disposable batteries... Besides, we should use electrical equipments which are energy - saving. Such as using lights and fans that have low capacity, or using equipments which reserve electricty. Not only do 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 summary, we need to save energy so that energy isn't run out and continues to serve human's life.

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.
