34 绪言 Introduction 香港所需的能源差?多全赖外地供应.能源 主要经由直接进口(如油产品及煤产品), 或从进口燃?转化而成(如电?及煤气). Hong Kong derives its energy supplies almost entirely from external sources. Energy is either imported directly (as in the case of oil products and coal products), or produced through some intermediate transformation processes using imported fuel inputs (as in the case of electricity and gas). 自2006 ??初开始,香港亦有很小规模的风 ?发电.此外,由2007 ?开始,垃圾堆填区 的沼气已用作生产煤气的燃?. Hong Kong also has very small scale wind power generation as from early 2006. In addition, landfill gas has been utilised as the fuel for gas production as from 2007. 除结集其他刊物内有关的能源统计?字外 (如香港对外贸?统计?字中的燃?进口? 字),本报告书亦包括从其他途径搜集的能 源统计?字,资??源在第2页「能源统计? 字的种?及?源」的章节?内?明. Apart from collating energy statistics published elsewhere (such as those on fuel imports from Hong Kong external trade statistics), this report also contains information obtained from various data sources as mentioned in the section Types and Sources of Energy Statistics on page 2. 本报告书每?出版一次,而每季出版的能源 统计季刊则提供最新的能源统计资?. This report is updated annually, with quarterly supplements to provide the latest energy information. 1997?7月1日,香港成为中华人民共和国的 特别?政区.在本系?报告书中就1997?7月 或以后的统计资?而言,「香港」是指香港 特别?政区. On
