Recently, certain political, social and governmental groups have put down the changes in the Earth’s climate to the effect of carbon dioxide (CO₂) of anthropogenic (human, industrial) origin. The first part of the paper provides important arguments to refute this view. Then, through the analysis of the rates of primary fuels in electricity production, it is proven what a significant rate coal types represent in the world and in some leading countries. It is also presented in detail what rates are forecast in electricity supply for the future (2020, 2035, 2050). Comments are made about the fact that in spite of her significant coal resources that can be economically exploited, Hungary is planning an unjustifiably low (4%) coal rate.
