Resumen del autor, extraído del trabajo. In the paper the advantages and disadvantages of two energy carriers: coal and natural gas were compared and the „coal-natural gas" model was indicated as most adequate in the Middle European countries conditions. The governmental activities should concentrate on the following issues: n technological and economic-financial optimisation of energy model n diversification of directions of energy carriers import. n necessity to obey international relations with respect to the global environmental policy. n possibility of long-term contracts with energy-exporter countries, taking into account their social and political situation. Attention should be paid to the possible participation in foreign investments giving an access to energy sources. n exploitation requirements, especially saving own energy resources and creation of strategic reserves. n possibility of linking own power systems to the regional structures, e.g. EC systems. It should be born in mind that „energy weapon" exists and once used deliberately and forcefully can bring about serious economic and political conditionings of the Middle European countries. They are in a special situation where the energy model should be re-oriented to the pro-ecological one.
