This paper describes a new point of view for the environment and energy education that is the important task to teach the urgent and serious issue of the global warming. The key context of this paper is to introduce the tacit knowledge into the environment and energy education also with explicit knowledge. The tacit knowledge, in this field, is a private and social custom to behave alert and agile based on environment friendly mind. The teachers should introduce their class to educate such custom and sense through experiences in the natural environment and field works. The simply way to behave like environment friendly is to say "mottainai" and act with a sense of "mottainai".
