Energy Transformation Technologies for Electricity

There are various methods to obtain electricity (i.e., electricity generating methods) from primary energy resources, some of which are being used currently. It is expected that the proportion of electric energy in the total energy consumption (i.e., dependence on electricity) will continue to increase steadily, and therefore the importance of the technology for transformation of energy into electricity, which means methods to obtain necessary electric energy, will grow further in the future. In this paper, we will review the technology for transformation of energy into electricity and outline the technological challenges.
