Nuclear power uses one of the most modern energy technologies, and the fastest growing.
Since the first commercial-scale plant was put into service (1956), nuclear power is currently used in 29 countries, where 439 plants have been built (July 2010). The latter meet approximately 15% of the world’s electricity demand. It’s the main generation source in Europe: this technology meets roughly 30% of power consumption, more than gas and about the same as coal.
The total installed nuclear capacity worldwide amounts to approximately 375,000 MW, which in 2009 generated 2,560 billion kWh.
Furthermore, 59 new plants are under construction in 14 countries, 149 more are planned and 344 have been proposed.
