it is undoubtedly very irrational? to determine exactly which of the various new sources of energy is more promising. After all,different countries and regions have different natural environment and market need.

But in general terms,solar energy may be more competitive in the renewable energy market. The broad sense of solar energy includes the Earth's wind energy,chemical energy,water energy and so on. In this critical,the main solar energy we are talking about is photovoltaic power generation and photo thermal.

Solar energy,as one of the cleanest sources of energy has little environment impact,is not geographically restricted and does not need to be mined,as compared to other renewable sources.At the same time,however,solar energy is also unstable due to the rotation and topography of the Earth. But with the  development of other energy sources,solar energy can also complement energy journeys such as the wind.

In this world which changes at every time,the technology of application of renewable sources will be more and more mature. We believe that the day renewable sources come completely into our life is coming.
