For instance, conscious of the resulting energy savings, we can all take small actions to make things better: the person who commutes by car can try riding a train, bus, or bicycle instead, the person who automatically rides the office elevator can try taking the stairs sometimes, and the person who finds lights and OA equipment on but not in use can turn them off.
If everybody finishes their daily work on time and leaves the office, electricity for office lighting, OA equipment, and air conditioning is saved. But if even one person remains in the office, he uses electricity. He may say that he knows he should leave earlier but it is difficult. At least during the summer solstice period, when days are longest, why not leave the office on time and enjoy your after-work hours?
Does your child tell you: "Daddy, you are leaving the lights on!"? Why not have everybody in the family think about the environment on this day? For instance, participate in "Candle Night" by turning off electric lights, spending time by candle light, and looking up at the night sky. You may find an opportunity to discuss some things normally hard to talk about.
