不久前,两个独立的研究小组分别在《科学》杂志上报道:他们在利用太阳能合成化学燃料方面都迈出了关键的一步。如果这些新的研究工作能够改进,科学家们就可以利用地球上最丰富的可再生能源,为从工厂到汽车等等一切消耗提供能源,同时不会产生额外的温室气体。现在,人们平均消费15万亿瓦的电能,其中85%来自石油、煤和天然气等化石燃料。大量化石燃料的消耗产生了一些严重的负面效应,包括气候变暖、海洋变酸、石油泄漏等现象。随着全世界能源消耗的增加,预计
Not long ago, two independent research groups reported separately in Science magazine that they took a crucial step towards using solar energy to synthesize chemical fuels. If these new research efforts can be improved, scientists can take advantage of the most abundant renewable energy on earth to provide energy for everything from factories to cars and more without generating additional greenhouse gases. Now, on average, people consume 15 trillion watts of electricity, 85% of which come from fossil fuels such as oil, coal and natural gas. The depletion of large quantities of fossil fuels has had some serious negative effects, including the effects of climate warming, ocean souring and oil spills. As world energy consumption increases, it is expected
