In Freud’s model of the mind, it is the id that contains a pool of primal psychic energy. It is the id that paves way into how we deal with the everyday pleasures of our lives. The id is governed by the pleasure principle were it is highly motivated for doing pleasurable things like hunger, sex, thirst, and many more. It is considered to house primal psychic energy because it is primarily consisted of all the inherited biological aspects that are necessary in our lives. Since it contains the pleasure principle, it is responsible for our impulses as well.
