Save Energy! It persuades us to be a wiser when we use energy. Have you did it as your habit? Since last year, in my dormitory, I took initiative to make a note to save more energy. I post a simple sentence like ?save energy, please!? in the power supply terminal. And I and my roommate tried to make it an habit.

This January, I got a chance to take an internship in Indonesia Power, a company which produces electrical energy or called power system generation company. Here, I learned that produces electrical energy is not simply as we imagine, it needs more extra resources untill electrical energy produced. With the resources we have, we never got 100% efficiency, to much energy lost.

Here, with the coal (I know it is not friendly for our mother earth) as main energy, electrical energy produced. In Indonesia, the coal still be a main energy to produces electrical energy. I don?t know when it end, may be until no coal found. The Renewable energy such as Water and Geothermal Energy still didn?t maximal to covered electrical needed in national scale of Indonesia.

Here I realize that our habit as electrical consumer should be change to be wiser.
