Energy is an essential material basis for human survival and development. Over the entire history of mankind, each and every significant step in the progress of human civilization has been accompanied by energy innovations and substitutions. The development and utilization of energy has enormously boosted the development of the world economy and human society. Over more than 100 years in the past, developed countries have completed their industrialization, consuming an enormous quantity of natural resources, especially energy resources, in the process. Today, some developing countries are ushering in their own era of industrialization, and an increase of energy consumption is inevitable for their economic and social development. China is the largest developing country in the world, and developing its economy and eliminating poverty will, for a long time to come, remain the main tasks for the Chinese government and the Chinese people. Since the late 1970s, China, as the fastest growing developing country, has scored brilliant achievements in its economy and society that have attracted worldwide attention, successfully blazed the trail of socialism with Chinese characteristics, and made significant contributions to world development and prosperity. China is now the world's second-largest energy producer and consumer. The sustained growth of energy supply has provided an important support for the country's economic growth and social progress, while the rapid expansion of energy consumption has created a vast scope for the global energy market. As an irreplaceable component of the world energy market, China plays an increasingly important role in maintaining global energy security. Guided by the Scientific Outlook on Development, the Chinese government is accelerating its development of a modern energy industry, taking resource conservation and environmental protection as two basic state policies, giving prominence to building a resource-conserving and environment-friendly society in the course of its industrialization and modernization, striving to enhance its capability for sustainable development and making China an innovative country, so as to make greater contributions to the world's economy and prosperity.
