Of the total 164 sources of geothermal in the northern midlands and mountains of Vietnam, up to 18 sources with surface temperatures > 53 degrees can allow the application of power generation purposes. [68] The geothermal potential throughout the territory of Vietnam is estimated at 300 MW. [10]
In 2017 the energy intensity of Vietnam's economy (E/G) was 5.7 MJ per year-2010 US$, above the world average of 5.2. [37] That was also higher than other ASEAN countries, for example Thailand (5.3) and Indonesia (3.5). This reflects the high level of energy use associated with Vietnam's industrialization and its heavy reliance on coal. [37]
Geothermal energy has been exploited as a source of heat and/or electric power for millennia. Geothermal heating, using water from hot springs, for example, has been used for bathing since Paleolithic times and for space heating since Roman times. Geothermal power (generation of electricity from geothermal energy), has been used since the 20th ...
Indonesia has an estimated potential of 29 GW of geothermal energy resources, the largest in the world; in 2017, its installed capacity was 1.8 GW. Geothermal power is considered to be a sustainable, renewable source of energy because the heat extraction is small compared with the Earth's heat content. [7]
Geothermal activity mostly appears in volcanic provinces, where it is fueled by the presence of a magma chamber. In some rare cases it can be caused by underground fires or by large deposits of radioactive elements. Other sources of internal heating can be gravitational differentiation of substances, tidal friction, metamorphism, or phase ...
Geothermal energy is a type of renewable energy that encourages conservation of natural resources. According to the US Environmental Protection Agency , geo-exchange systems save homeowners 30–70 percent in heating costs, and 20–50 percent in cooling costs, compared to conventional systems. [ 29 ]
Especially, Northwestern Vietnam is the most prospective region for geothermal exploration and development. [3] Dr. Doan Van Tuyen from the Institute of Geological Sciences of the Vietnamese Academy of Science and Technology commented, "Compared with the rest of the world, Vietnam has medium potential for geothermal energy development.
The geothermal gradient has been used for space heating and bathing since ancient Roman times, and more recently for generating electricity. As the human population continues to grow, so does energy use and the correlating environmental impacts that are consistent with global primary sources of energy. This has caused a growing interest in ...
