Solar Energy

Solar energy should be more widely used in the near future. There are some reasons to support my opinion as follow. At first, solar energy can be used unlimitedly, and secured from anywhere in the earth. Furthermore, the cost of this resource is without charge for it is a kind of natural energy that is free to obtain. And then, it would not cause any pollution to endanger our environment. For example, solar energy can be made hydrogen via electrolysis technology. According to scientists, the hydrogen is the best fuel if it can be used effectively. And its residual product is the only water. Base on these reasons, I deem that the solar energy should be more widely used in the near future.
