Currently, the portion of natural gas is higher than nuclear one and lower than coal one.

Some dynamic factors explain this: (i) the discovery of significant natural gas reserves and interconnection of markets have changed the perspective, especially in Europe, natural gas as a product with limited availability and reserved for more noble purposes, (ii) the expansion of combined cycle turbines causes generating electricity from natural gas more efficient, increasing its competitiveness against other sources, and (iii) liberalization of industries reduced institutional barriers to new entrants.
