2025年教学资料:二年级环保板报
二氧化碳但关心全球气候变暖的人们却把减少二氧化碳实实在在地带入了生活转向低碳生活方式的重要途径之一,是戒除以高耗能源为代价的“便利消费”嗜好。“便利”是现代商业营销和消费生活中流行的价值观。不少便利消费方式在人们不经意中浪费着巨大的能源。比如,据制冷技术专家估算,超市电耗70%用于冷柜,而敞开式冷柜电耗比玻璃门冰柜高出20%。由此推算,一家中型超市敞开式冷柜一年多耗约4.8万度,相当于多耗约19吨标煤,多排放约48吨二氧化碳,多耗约19万升净水。上海约有大中型超市近800家,超市便利店6000家。如果大中型超市普遍采用玻璃门冰柜,顾客购物时只需举手之劳,一年可节气4521万度,相当于节省约1....
