ABSTRACT
This chapter provides an interdisciplinary understanding of the basis of energy science and proposal of solutions. The law of conservation of energy states that the total amount of isolated energy does not change. For any two different states, the difference in their total energy is zero. In particular, the law of conservation of energy in thermodynamics is called the first law of thermodynamics. It is a basic law of thermodynamics. Power generation converts other forms of energy into electric power. Examples of artificial power generation include hydraulic power generation, wind power generation, solar power generation, geothermal heat generation, thermal power generation, and nuclear power generation. Nuclear fusion energy is extracted by nuclear fusion of atoms and isotopes with small, light nuclei such as hydrogen and helium. The reaction is called nuclear fusion reaction. Nuclear fission reactions like nuclear power generation utilize particularly heavy elements such as uranium.
