Solar energy is a renewable source of energy because it comes from the sun. It's clean and safe but it's unpopolar now.
We need energy to live and work. Our major source of energy is oil. Oil is one kind of fossil fuel. The amount ot fossil fuels in the world is limited. Therefore, we must save it, and at the same time, we must find new sources of energy. Geothermal heat and nuclear power are alternative sources of energy. They can give us electricity. Other alternative sources are the sun, waves and water. These sources are not only unlimited and available but also clean and safe for the environment. People should develop and use them more and more in the future.
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure.
Coal gasification can be used to produce syngas, a mixture of carbon monoxide (CO) and hydrogen (H2) gas. . The use of coal as fuel causes adverse health impacts and deaths. Coal mining and coal fueling of power station and industrial processes can cause major environmental damage.

+ 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.

I only know one paragraph.
Nowadays, due to the shortage of energy, the use of green technology from renewable resources such as wind, sun and water is becoming more and more important and urgent.
Among these green energy resources, energy from the sun or so-called solar energy is considered to be the most available one.
First and foremost, solar energy comes directly from the sun which is an abundant source of renewable energy. Thus, it is sustainable. Besides that, thanks to its natural source, this type of energy is environmentally friendly and does not cause pollution. Furthermore, solar energy is available everywhere in the world, especially in countries near the Equator. Additionally, its devices, such as solar panels do not have moving parts and are very quiet to operate. However, the implementation of solar energy consumption has its own drawbacks.
First, it costs lots of money to operate. Solar panels are expensive to produce because they are made from rare and special materials. The technology used to store solar energy is also costly. Secondly, though the sun is available everywhere, the access to sunlight is limited at certain times, such as on rainy days or in the evenings. What's more, although solar energy is greener than fossil fuels, the production of solar panels may cause greenhouse gas emissions. In conclusion, there is no known energy that is totally safe and perfect to use. It is expected that in the near future, new green technology will be developed to reduce or eliminate the disadvantages that are mentioned above.
