Ghosts need energy to manifest, this energy can be of different types but the most often used is thermal energy, that is heat taken from the surroundings that the ghost uses to let itself be known to people in the area.
(I have wondered if the level of heat taken from the area compares to the type of haunting that is witnessed, such as if one amount of heat is used up you get sounds, or if it gets really cold, due to more heat being taken then you get visual phenomenon.)
Poltergeists take there energy from people, and that is why they seem to plague people, due to them staying with that person so it can leach off if them. The Polt takes the energy from people in the form of emotional and actual energy leakage that is given off by the person, hence the throwing of items, to try and scare the people near it so it can feed off the energy they give off.
Psychics do give off an energy, it is one of the ways in which they communicate with the spirit world. They feel drained after the communication due to the energy that they use up in doing so. It is similar to the energy leached by ghosts and polts but with psychics it is the psychic that uses it, and not the ghost.
