Current status of electricity generation in the world and future of nuclear power industry

It is well known that the electrical-power generation is the key factor for advances in any other industries, agriculture and level of living (see Table 1) [1]. In general, electrical energy (see Fig. 1a) can be generated by: 1) non-renewableenergy sources such as coal, natural gas, oil, and nuclear; and 2) renewable-energy sources such as hydro, wind, solar, biomass, geothermal and marine. However, the main sources for electrical-energy generation are: 1) thermal primary coal and secondary natural gas; 2) “large” hydro and 3) nuclear (see Fig. 1). The rest of the energy sources might have visible impact just in some countries (see Fig. 1c,e). In addition, the renewable-energy sources, for example, such as wind (see Fig. 2) and solar (see Fig. 3) and some others, are not really reliable energy sources for industrial-power generation, because they depend on Mother nature and relative costs of electrical energy generated by these and some other renewable-energy sources with exception of large hydro-electric power plants can be significantly higher than those generated by non-renewable sources.
