In Vietnam, the tidal energy potential is not large, can only reach 4GW capacity in the coastal areas of the Mekong Delta. However, the large potential area that has not been studied is the coastal waters of Quang Ninh - Hai Phong , especially Ha Long Bay and Bai Tu Long , where the tidal range is high (> 4m), and many islands do dikes for ...
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]
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 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 ...
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 ]
The main motivation to replace fossil fuels with renewable energy sources is to slow and eventually stop climate change, which is widely agreed to be caused mostly by greenhouse gas emissions. In general, renewable energy sources cause much lower emissions than fossil fuels. [12]
The Sonoma Calpine 3 power plant is one of 22 power plants at The Geysers in the United States. This is a list of operational geothermal power stations with a current installed capacity of at least 10 MW. The Geysers in California, United States is the largest geothermal power station in the world with a nameplate capacity of 1,590 MW and an annual generation of 6,516 GWh in 2018. Geothermal ...
