I'm not green too. But, when I was elementary school student, I took a bath in dark bathroom not to use much electricity. So, my mother was surprised and said to light on. Now, I try to reduce energy to use but I'm not sure I can reduce it.
By the way, I'm going to go to Enoshima and clean the beach. Enoshima is famous for its beach and many people visit there in Summer. But, some of them leave a lot of garbage. So, the beach is always dirty.
