Lower demand reflects both the current weakness of economic activity, particularly in Europe and China, and, more important, the longer-term changes in technology, which will increase cars’ fuel efficiency and induce the use of solar power and other non-oil energy sources. The increase in the future potential supply of oil reflects new output produced by fracking, the development of Canada’s tar sands, and Mexico’s recent decision to allow foreign oil companies to develop the country’s energy sources.
今天的价格所反映的市场预期表明未来需求较低而未来供给较高。低需求反映了当前经济活动的疲软局面（特别是欧洲和中国），更重要的是，它还反映了技术的长期变化——汽车燃油效率将有所提高、太阳能和其他非石油能源资源日益重要等。未来潜在石油供给的增加反映了液压致裂法所带来的新产出、加拿大沥青砂开采和墨西哥最近决定允许外国石油公司开采本国能源资源等。
