Not all countries with similar socio-economic development require similar level of per capita energy consumption to function. Even within developed world, there is a huge variation on per capita energy use. At first look at South Asia. In 2014-
Bangladesh-222kg
Pakistan-484kg
India-637k
So, Pakistan's energy consumption is twice of Bangladesh and for India, it is 3 times. but such level of disparity can also be seen among the G7 countries(most developed economies in the world). In 2014-
Italy-2414kg
UK-2777kg
USA-6956kg

So, USA per capita energy use is 2-3 times of UK and Italy. For USA to match UK and Italy, you have to go back at least 100 years, not 1950s. Because even in 1960, US energy consumption was 5641 kg oil equivalent. Now it would be entirely absurd to claim that, UK and Italy's economy function similar like USA in early 1900.
There are several reason why Bangladesh's energy use per capita is less. Bangladesh's main industry, Garments is a low energy consuming industry. It requires mainly human labor. Bangladesh's private motor vehicle fleet is much smaller than India or Pakistan. In Bangladesh, private motor vehicle ownership is discouraged by imposing a very high tariff. Unlike in India, Bangladesh do not have high energy consuming heavy industries, like steel making, automobile manufacturing etc. Bangladesh electricity consumption in 2014 was much less than now. Our climate is much mild compared to many region in India or Pakistan. We do not need central heating during winter or demand of Air Conditioning in summer also less. Our temperature rarely drop below 10 degree Celsius in winter and rarely go beyond 38 degree Celsius in Summer. All these factors weigh on why Bangladesh has low per capita energy use compared to India or Pakistan.
