能源挑战我们知道,为了避免气候变化带来最恶劣的影响,人类必须在2050年以前实现全球二氧化碳排放量减半。然而,应对气候变化的措施必须同时兼顾人口增长、经济发展和能源需求迅猛增长等因素。从2000年到2050年,随着全球人口从70亿增长到90亿,加上非经合组织国家的经济持续高速发展,全球能源需求可能会翻 Energy Challenges We know that in order to avoid the worst effects of climate change, mankind must cut its global carbon dioxide emissions by half by 2050. However, measures to combat climate change must take into account both population growth, economic growth and rapid growth in energy demand. From 2000 to 2050, as the global population increases from 7 billion to 9 billion, and the sustained rapid economic growth in non-OECD countries, global energy demand may turn up
