   Not sure what you mean by "it", but I doubt that many new coal plants   
   are built in the first world (maybe in Australia?); Wind power faces   
   significant opposition in some countries.   
      
   Concerning nuclear power: it stagnates or is in decline in the first   
   world.  E.g., a number of nuclear power plants were shut down in the   
   2010s in the USA despite being granted lifetime extensions, due to   
   being uneconomical in the fracking age, and the building of new   
   reactors led to huge cost overruns (Nukegate) and the bankruptcy of   
   Westinghouse, and to the cancelation of some of the projects.   
   Similarly, the first EPRs in Finland and in France led to huge delays   
   and cost overruns, and a large part (all?) of the losses were   
   shouldered by the French state, which restructured the companies   
   involved.  The Chinese EPRs also had long delays, but were the first   
   to deliver grid energy.   
      
   In any case, no AP-1000 has been built in Europe, and no EPR in the   
   USA.  Both have been built in China.

   They are willing to build different things.  France has announced the   
   building of 15 EPRs to replace much of its aging reactor fleet (which   
   is not that much less than what China is building).  It will be   
   interesting when in 30 years defects are found in one of the reactor   
   vessels of an EPR (like happened for an older model in 2022), and all   
   EPRs have to be shut down for inspection and repairs (like happened   
   for that model in 2022).
