戦前日本の家庭エネルギー消費は薪に大きく依存しており、１９２０年代まで薪の使用は８０％以上の比率を占めていた。木炭も含めた森林エネルギーは１９４０年においてさえ４分の３を占めていた（これは投入ベースでのデータであり、薪炭の重要性は多少誇張されている）。１９１０〜２０年代には電力利用の増加が顕著で、１９３０年代には代用炭が急増した。都市部のエネルギー消費は１９００年代以降順調に増加し、エネルギー源の多様化も進んだ。また郡部に比べると木炭の割合が高く薪と同程度に消費されていた。

Household energy consumption in Japan before WWII was highly dependent on firewood and it had been over 80% until 1920's. Even in 1940, the forest energy including charcoal was three quarters. (this is the input-based data, so the importance of firewood has been somewhat exaggerated.) Increase in power use is remarkable in 1910-20's and the substitute coal penetrated in the 1930s. Energy consumption in urban areas steadily increased after the 1900s and diversification of energy sources also advanced. Further, the ratio of charcoal had been consumed as much as firewood compared to rural districts.

Before the war, Japanese household energy was mainly relying on firewood, and the usage ratio of firewood until the 1920s was over 80%. Forest energy including Charcoal took 3/4 of the all type of energy (this data is based on supply , therefore the importance of firewood and charcoal is slightly exaggerated).
The increase of electricity usage was remarkable from the 1910s to the 1920s, then in the 1930s the alternative charcoal has increased. The Energy consumption in urban area has smoothly increased in the 1990s and the energy resource also became diversified. Compared to rural area, the usage ration of charcoal is high which was consumed as much as firewood.

In the pre-war period, the consumption of energy in general houses was largely dependant on wood fuel, and usage of wood composed more than 80% until 1920s. Forest energy including charcoal consisted three fourths even in the 1940s (this data is based on input, and the importance of wood fuel is somewhat exaggerated).
Between 1910~1920, the increase of electricity usage was drastic, and in the 1930s charcoal substitution increased rapidly. After the 1900s, energy consumption of urban areas rose steadily, and energy source became multifaceted. Also, the ratio of charcoal was higher compared to rural areas, and the amount of consumption was similar to that of wood fuel.

Before the end of WW II, energy consumption by Japanese households was hugely dependent on wood, accounting for more than 80% of the entire energy consumption until the 1920's. Even in 1940, forestry energy including charcoal accounted for three-fourths of the energy use (this figure was based on supply, however, and the importance of charcoal was slightly exaggerated). From 1910 to 1930, the use of electricity increased rapidly. In the 1930s, substitute coal was more widely used. Energy consumption in cities increased gradually after the 1900's, and energy resources became more diversified. Although the use of charcoal and wood was the same in the cities, they consumed a higher percentage of charcoal than rural areas.
