For example, cutting a ton of CO2 with on-shore wind turbines in Germany probably costs about $35, avoiding about 14 cents of climate damage per dollar. But offshore wind turbines cost about $150 per ton of CO2, avoiding just three cents of climate damage per dollar.
比方说，在德国安装海岸风电机组减排一吨二氧化碳约耗资约35美元，每投入1美元能避免约14美分的气候损失。但海上风电机组减排一吨二氧化碳约耗资150美元，每投资1美元只避免了3美分的气候损失。
