The solar wind is a continuous source of energy for the Earth's magnetosphere. One
very important scientific problem is the energy transfer from the solar wind into the
magnetosphere. This is the main issue when studying the evolution of the
geomagnetic storms or when attempting their prediction, because there is no direct
link between the transferred energy and the magnitude of the storm.
We will overview the current state of this problem and present the methods proposed
to evaluate this transfer. We will also present a synthesis of our results concerning the
energy transfer during intense geomagnetic storms that occurred in solar cycle 23. A
detailed analysis of the geomagnetic storm that occurred on November 6, 2001 will be
included.
