重新发明“火”——能源使用的伟大变革

Re-inventing“fire”–a sea-change in energy use

"旧火"即化石燃料的燃烧,对经济、安全、健康、环境的威胁越来越大。因此有必要重新发明"火",彻底改造现有的能源系统。"新火"的关键是最大程度地利用可再生能源和大幅度提高能源利用效率。节能的重点在交通、建筑和工业领域。其中,交通领域节能的重点是汽车"轻量化"和材料"新型化";建筑领域节能的重点是窗户隔热保温和一体化设计;工业领域节能的重点是采用优化设计和改造。电力是通向"新火"时代的关键,也存在巨大的节能潜力。未来的能源供应将逐步转向分布式的可再生能源。利用"新火",到2050年,美国的能源系统将不再使用任何石油、煤炭和核电,同时经济规模将达到目前的2.6倍。重新发明"火"与节能减排的理念完全一致。

'Old fire'means the combustion of fossil fuel which poses an increasing threat to the economy,safety,health and the environment.This necessitates re-inventing'fire' and completely converting the present energy system.The core of'new fire'is maximum use of renewable energy and much improved energy efficiency.Energy conservation work should be focused on transportation,buildings and industry.Energy conservation work in the transportation sector aims to reduce the weight of vehicles and use new types of materials;while in the building trade it aims to adopt thermal insulation of windows and integrated design; and in industry it aims to optimize design and retrofit. Electricity,the main path to the'new combustion'era, has huge potential for energy conservation.The energy supply will gradually shift to distributed renewable energy. With'new fire',the energy system of the US will no longer use petroleum,coal or nuclear power by 2050 and support its economic scale reaching 2.6 times today’s.The reinvention of'fire'coincides with the idea of energy conservation&emission reduction.
