Abstract

Being the public resource for the survival of human beings and the development of society, energy is the material guarantee for national and regional economic development. Energy is not only economic resource, but also strategic and political resource. The sustainable development of energy directly infl uences China’s security and modernization. However, owing to the prolonged utilization of tremendous amount of fossil fuel, greenhouse gases are emitted and accumulated in the atmosphere. This exacerbates greenhouse effect, which leads to the significant increase in the frequency of natural disasters and extreme climate conditions, and threatens the sustainable development of human society, and hence challenges the energy structure with fossil fuel as its core. In such a condition, China appeals to the development of new and renewable energy and establishment of efficient, economical, clean and sustainable energy supply system, which will push forward the revolution of technology and advancement of civilization and society.
