Today I will update a posting of a dozen years ago, entitled:       WHAT IS THE STATE OF WIND ENERGY TODAY? In that blog of 5 August 2011 I said: In 2010 almost 40,000 MW of new wind energy conversion systems (WECS) became operational, an equivalent of 47 nuclear power plants (850 MW/reactor).  The world total now is at around 200,000 MW of WECS, or said to be  the equivalent of 235 nuclear facilities.    There are   442 nuclear power plants in 30 countries having a net electricity capacity of 375,000 MW, with 63,000 MW in 16 countries under construction .  However, almost half the new nuclear construction projects are in China, which has murmured the possibility of reviewing this option.  Germany will shut down all its nuclear plants by 2022 and Japan is in a real dilemma . So I will first see  how nuclear power has changed during these dozen years . Countries with nuclear power today = 32, or two more Number of power plants = 438, or four less Total capacity in megawatts electricity
