兄弟们看清楚，小弟要的是太阳能不被广泛利用的文章。

答案

There are three reasons why solar energy has not been made use of widely.One is its high cost,if people wants to use the solar energy,it must cost him a lot to do so.It costs much higher than the water energy and mineral energy.Second reason is about the weather,it is impossible that everyday is sunny day on the earth.So if there is not enough sun in the sky,the solar energy will not be used so much.The last reason is about the techinical person,because there are still few person who are very professional on developing solar energy used.Not only it need a lot of money to develop this techinic,but also this techinic is highly complesity.However,the solar energy is still a good energy that can be used by people in the future.
