【简答题】
众所周知，煤炭是不可再生能源，地球上储量有限．节约能源关系到子孙后代的生存．火力发电是利用煤炭燃烧来发电的，煤炭在燃烧时会释放大量二氧化碳、二氧化硫等有害气体，能形成酸雨和大气污染．会造成全球气候灾难性的变化．节约1kW?h电约少消耗0.4kg煤，约少排放0.5m 3 二氧化碳和30g二氧化硫．因此，节约用电具有重要的现实意义． （1）现居住在苏州的人口大约有1000多万，约有350万个家庭．假设每个家庭原来用、三盏60W的普通灯泡照明，每天每盏灯正常工作4h，现将60W的普通灯泡都换相当的11W节能灯．请你估算： 苏州市每天能节约多少千瓦时电？这些电若由火力发电厂提供，则需消耗多少千克煤？ 产生多少千克二氧化碳（二氧化碳的密度为1.98kg/m 3 ，估算时可取2kg/m 3 ）？ （2）为增强节能环保意识，倡导低碳生活，请你从节约用电的角度再提出一条合理化建议：______．
