机械和设备制造对未来能源市场的发展和形成起着关键作用。近年来,能源需求在世界范围内持续增长,目前还看不到该增长有结束的迹象。其原因在于世界人口和发展中国家需求的不断增加。根据国际能源协会 (IEA)的资料,过去30年间,每年的能耗从460亿吨增加到730亿吨。其中近60％是石油(约 42．6％)和天然气(16．4％)。且石油的比例有所降低,天然气比例则不断上升。
Machinery and equipment manufacturing play a key role in the development and formation of the future energy market. In recent years, energy demand has continued to grow worldwide. At the moment, there is no sign that the growth is over. The reason for this is the growing demand of the world’s population and developing countries. According to the International Energy Agency (IEA), the annual energy consumption has increased from 46 billion tons to 73 billion tons over the past 30 years. Nearly 60% of them are oil (about 42.6%) and natural gas (16.4%). And the proportion of oil has been reduced, the proportion of natural gas is on the rise.
