The Alternative Energy Sources: Solar Energy

In my opinion, solar energy will be more widely used in the near future. As most of people have known that the sun is a renewable and easily receive energy source. And the natural scientists infer that the sun will expected to shine for 5 billion years at least. The solar energy is non pollution and productive. But one of the most effected drawbacks is too expensive. It cost too much to produce the energy. The next drawback is been limited by terrain and climate. Furthermore, it is inefficiency a cloudy day or a rainy day. Scientists are devoted to cost savings. Solar energy will be wide use in near future.
