安全：天然气的气体密度是空气密度的二分之一，比空气轻，极易蒸发，不易爆炸，天然气中所含的甲烷、乙烷、丙烷等自身是无毒性的。而液化气易蒸发、易自燃，毒性较大。
经济：在平等运用量（热值）的条件下比较运用瓶装液化石油气每月节约费用至少为25%—35%左右，不只会省去购买钢瓶和钢瓶定期检验费用开销，更会省去日常日子中转移、替换液化气所带来的费用和烦恼。运用天然气的费用比用电的费用节约35%以上。
环保：天然气的98%成分是甲烷，在彻底焚烧时只发生少数二氧化碳与水蒸气。天然气作为一种优质、清洁性、高效的绿色动力，是国家动力方针推行和遍及的动力。
便利：天然气经过天然气管道直接进入城市的千家万户，管道运送源源不绝，没有断气和替换钢瓶的烦恼，亦不需要在现场储存或增加，因为其便利性被群众称为“自来气”。
