Abstract: Energy is an important material foundation for economic and social development.By analyzing and judging the changes of global energy supply and demand pattern in the future is of great significance for the country to formulate energy strategies and plans.By forecasting global energy demand trends, analyzing global energy consumption structure and the changes of global energy market pattern, this paper predicts the new pattern of global energy supply and demand in the future.Firstly, the developing countries such as China, India and ASEAN will push up global energy demand, but consumption growth rate will slow down.Secondly, climate change promptes energy consumption to turn into more environmentally friendly way which means the proportion of nuclear power、hydro electric、renewable and other non-fossil energy will continue to increase.Thirdly, the United States is expected to basically achieve energy independence in 2020, becoming an important oil and gas supply center besides the Middle East and Russia, and will reshape the global energy market structure.
