Interesting story from my grandmother
I made interview with my grandmother (81years old) the other day. She told me very interesting stories.
When she was very young, major energy source used to be charcoal and firewood.
For example, they used firewood to prepare for hot water, bath, meal, and heating ..etc.
Then, many of new electric tools have developed as we all know.
For me, most interesting things to hear from her in this interview is that there were full of electricity around her life even it was during the World War Ⅱ.
Recent years, we learned electricity has become shortage year by year.
But, my question is that why electricity has become shortage recently although it was quite enough 50-60years ago as my grand mother said.
If her memory is correct, it can be said that we have used too much electric tools compared with 50-60years ago.
I want to point out these facts from my interview with grandmother.
