Energy crisis and environmental crisis prompted human thinking, looking for a way out. While fossil energy in the past hundred years time, the development of human society has made a huge role, but due to the limitations of its own： the non-renewable nature, environmental pollution and energy politicized, destined to be replaced. New energy in a tough energy and environmental situation become a new impetus for economic development. Of course, the new energy present due to various reasons, in the proportion of human energy consumption structure, the proportion accounted for far less than fossil fuels, technical issues, storage and transportation issues and cost issues still restrict the development and popularization of new energy. Nuclear, solar, wind, tidal energy and hydrogen energy are all new areas. Which in terms of nuclear and solar energy technology, the use is still relatively mature, the market prospects of other energy sources is also very tempting, in this paper, standing industrial perspective analysis of the market prospects of new energy solar and hydrogen energy.展开更多
