The first approximation expression for the solar wind-magnetosphere energy coupling function epsilon, which correlates well with the total energy consumption rate Usub (T) of the magnetosphere is described. It is shown that epsilon is the primary factor which controls the time development of magnetospheric substorms and storms.
