…There is a range in the calorific value of each type of coal, but in broader calculations, this is ignored and conversion factors such as 1 for anthracite/bituminous coal, 0.78 for subbituminous coal, and 0.3 to 0.6 for lignite (varies by country, with the United States and Canada at 0.5, Russia, China, and India at 0.33, and Australia, Germany, and Poland at 0.3) are used. The result calculated in this way is called the "coal equivalent (CE)." This type of conversion is also applied to calculations that span different energy sources, and it is common to express the amounts of oil and natural gas in terms of coal equivalents, and vice versa. … *Some of the terminology used to refer to "coal equivalent" is listed below.

…各炭質の中でも発熱量には幅があるが,広範な集計ではそれは無視して,無煙炭・歴青炭1,亜歴青炭0.78,褐炭0.3~0.6(国により異なり,アメリカ,カナダは0.5,ロシア,中国,インドは0.33,オーストラリア,ドイツ,ポーランドは0.3)のような換算係数を用いる。こうして計算したものを,〈石炭当量coal equivalent(ce)〉という。この種の換算は,異種のエネルギー源にまたがる集計にも適用され,石油や天然ガスの量を石炭当量であらわし,またその逆の換算をすることもよく行われている。… ※「coal equivalent」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
