Analysis of your energy consumption1.1) Comparison within my energy consumptionFollowing 1.3), energy consumption by time, I use many energy at10:30~16:00 and 23:00~24:0nt. But many percent of energy is used for transportation in my case.Namely transportation energy is much of energy in total energy consumption for today people.And I use many energy from electricity.(68%) Of course it is made with raw materials, but I my case, I use many electricity energy. Because electricity energy is good for transfer, and most of machine operate with electricity today. (Electricity energy is not good to store, so it isn't use for transportation)My total daily energy consumption is 41616KJIt can't feel how much energy.So I will calculate how long use light or machine like refrigerator... etcFirst my daily energy consumption, can light my room for 361 hour with 32W light. Second, my daily energy consumption, can operate my refrigerator for about 9 days. Also It is same energy with '5 days Food calories' for normal person.If I will live till 80, I will consumption energy same with firing 125852Kg coal or 26864Kg of crude oil or 22192Kg of LNG1.2) Comparison with anotby firing 4.31Kg coal. And it is 4 times of energy what I have to use vitally for live.68% of energy consumption is supplied with electricity and 12% is supplied with LNG form.Second, I use small energy than average energy consumption because I don't use many energy for transportation. But when I graduate school and have car or move long distance for office, It will be similar with average energy consumption.Also, Now It isn't cold and hot, so energy for cooling or using heater isn't calculate in my energy consumption. It is essential reason why my energy consumption is very small than average consumption per personThird, My energy consumption isn't any amount of energy comparing with average energy consumption per person, but it isn't small energy. If I will live till 80 years old, My total energy consumption is same with energy which is made by firing 26,864Kg of coal.Not only I know about fact about my energy consumption but also I think about energy consumption deeply.Transportatioe
