法国原本是一个能源并不富裕的国家,依靠进口石油作为主要燃料。70年代的世界石油危机,迫使他们不得不采取节能措施,减少能源消耗,同时开始大力开发核能发电。今天,在法国,能源供应,应该说已经不很紧张。但是他们居安思危,并没有放松对节约能源的努力。在建筑节能方面尤为突出。1984年法国的建筑能耗还占全国总能耗的42％～45％,由于建筑节能的有效开展,到1990年建筑能耗已降到总能耗的28％。目前法国住宅建筑每年的采暖能耗较1973年以前要节约2600多万吨标煤。法国的建筑节能投资,一般在10年之内便可回收,经济效益非常显著。更何况常用的能源大都为一次性不可再生能源,用一点少一点,总有枯竭的一
France was originally a country where energy was not abundant, and it relied on imported oil as its main fuel. The world oil crisis of the 1970s forced them to adopt energy-saving measures to reduce energy consumption and began to vigorously develop nuclear power. Today, in France, energy supply should be said to have been less stressful. However, they were prepared for peacetime and did not relax their efforts to save energy. Especially in building energy efficiency. In 1984, the energy consumption of buildings in France also accounted for 42% to 45% of the total energy consumption in the country. Due to the effective development of building energy efficiency, the energy consumption of buildings had dropped to 28% of the total energy consumption by 1990. At present, the annual heating energy consumption of French residential buildings is more than 26 million tons of standard coal than before 1973. French investment in building energy efficiency is generally recoverable within 10 years and the economic benefits are significant. What’s more, most of the commonly-used energy sources are one-time non-renewable energy sources. With a little less, there is always a depletion.
