新西兰有丰富的煤炭资源,最近又在陆上的卡普尼和海上的毛尼两地发现了天然气,然而至今仍没有发现有开采价值的油田。为了减少30～50％的石油进口量,应该利用下列燃料:液化气、天然气、合成石油和沼气。但是,生产液化气仅能利用10％的天然气,还必须为90％的剩余物另觅用途。除此之外,液化气的生产设备相当昂贵,采用更 New Zealand has abundant coal resources, and recently discovered natural gas in Kapuni on the land and Mauni on the sea. However, there are still no oil fields that have been discovered to date. In order to reduce oil imports by 30 to 50%, the following fuels should be used: liquefied gas, natural gas, synthetic petroleum and biogas. However, the production of liquefied gas can only use 10% of natural gas, and it must also be used for other purposes. In addition, liquefied gas production equipment is quite expensive and more
