Abstract :
The present contribution of DG in the total power production at the great majority of countries is small (presently, in the whole world it is around 3%). But prospects for the future are much higher. An important feature of new DGs is that they predominately deal with clean energy, without pollution of soil, water and air. In that respect, their larger use will help utilities to fulfill strict Kyoto criteria from 1990 on environmental protection and hopefully new ones, expected to be issued in Copenhagen, at the end of 2009.
