炊事用のエネルギー消費量が増加しなかった背景には以下の理由が考えられる。まず食生活の充実は70年代半ばまでに既に達成されていた。その時期までに炊事機器の効率改善はある程度進んでおり、70年代以降の外食化やレトルト商品の普及もエネルギー消費を抑える方向に作用した。同時期、暖房用エネルギー消費の伸びも少なかった。理由としては暖房機器の普及が飽和していったこと、それらの熱効率改善が進んだことがある。暖房機器保有数は増加し、暖房を行う住空間は拡大したが、それらの影響は限定的であった。

The following reasons could be considers as reason for the increase in energy consumption for cooking. Firstly, the enhancement of people diets had already taken place by the 70s. Efficiency improvement of cooking equipment had also progressed to some extent by this stage. the spread of retort products and eating out of the 1970s also contributed to the the further reduction of energy consumption. At the same time, growth of the heating energy consumption was small. It was certain that the widespread use of heating equipment had already been, and that the advance of thermal efficiency improvements was the reason. The number of homes with home heating appliances increased, the room size expanded, but their effects were limited.

It is possible to assume the following reasons why energy consumption for cooking did not increase. Firstly, the dietary habit has reached it's peak in mid 70's. Until that period, the improvement of cooking appliances efficiency has progressed to an extent. After the 70's, the popularity of eating out and retort products reduced the rate of energy consumption to a downward trend. Meanwhile, the growth of energy consumption on heaters were also low. To summarize, the reasons are the use of heating systems had saturated and the improvement of heating efficiency was high. Although, the number of the heaters increased and the living space which it heats became larger, it's effect on energy consumption is limited.

The reasons behind amount of energy consumption for cooking didn't increase could be followings. At first, quality of diet was accomplished before late 1970's. Efficiency of kitchen appliances had been improved somewhat then, and also popularization of eat-out and retort pouched foods in 70's and after helped holding energy consumption down. At same time, energy consumption of heating didn't increase a lot. The reason could be slowing down of popularization of heaters, and also improvement of these heaters' thermal efficiency. Number owned of heaters increased, spaces of living to heat was expanded, but the influence was limited.
