| Abstract | The Earth and the oceans have a natural temperature gradient between the surface and given depths. The natural temperature gradient is used to operate renewable energy systems, such as power generation and space heating/cooling, which operate on similar thermodynamic concepts. For a given purpose, different technologies are used to extract heat from the two resources. Even though the concepts of the two systems are the same, their heat energy extracting performance is different. An overview of the similarities between the usage of the two thermal resources is presented in this paper. The energy balances at the surface of the Earth and the oceans are also presented. |
