Nesjavellir Geothermal Power Station
The Nesjavellir Geothermal Power Station (, ) is the second-largest geothermal power station in Iceland. The facility is located above sea level in the southwestern part of the country, near Þingvellir National Park and the Hengill mountain range, about 30 km east of central Reykjavík. The power station is owned and operated by ON Power. Plans for utilizing the Nesjavellir area for geothermal power and water heating began in 1947, when boreholes were drilled to evaluate the area's potential for power generation. Research continued from 1965 to 1986. In 1987, construction of the plant began, and the cornerstone was laid in May 1990. The station produces approximately 120 MW of electrical power; it also delivers around of hot water per second - with a heating capacity of 300 MWt, serving around half of the space heating and hot water needs of the Capital Region, the rest provided by lower temperature fields and the Hellisheiði Geothermal CHP plant.

The Hellisheiði Power Station (, ) is the eighth-largest geothermal power station in the world and largest in Iceland. The facility is located in Hengill, southwest Iceland, from the Nesjavellir Geothermal Power Station. The plant has a capacity of of electricity and th of hot water for Reykjavík's district heating. The power station is owned and operated by ON Power, a subsidiary of Reykjavík Energy. History Electricity production with two turbines commenced in 2006. In 2007, an additional low pressure steam turbine of was added. In 2008, two turbines were added with steam from Skarðsmýrarfjall Mountain. The hot water plant was introduced in 2010 and the last two high pressure 45 MW turbines were added in 2011. In order to reduce hydrogen sulphide pollution in the capital area, a system was added to the plant in 2014 which reinjects non-condensable gases into the ground.

Buildings And Structures Completed In 1990
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building pract ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renewable Energy In Iceland
Iceland is a world leader in renewable energy. 100% of the electricity in Iceland's electricity grid is produced from renewable resources. In terms of total energy supply, 85% of the total primary energy supply in Iceland is derived from domestically produced renewable energy sources. Geothermal energy provided about 65% of primary energy in 2016, the share of hydropower was 20%, and the share of fossil fuels (mainly oil products for the transport sector) was 15%. The Icelandic government aspires that the nation will be carbon neutral by 2040. The largest obstacles to this are road transport and the fishing industry. In 2015, the total electricity consumption in Iceland was 18,798 GWh. Renewable energy provided almost 100% of production, with 75% coming from hydropower and 24% from geothermal power. Only two islands, Grímsey and Flatey, are not connected to the national grid and so rely primarily on diesel generators for electricity. Most of the hydropower plants are owned by ...

Geothermal Power In Iceland
Geothermal power in Iceland refers to the use of geothermal energy in Iceland for electricity generation. Iceland's uniquely active geology has led to natural conditions especially suitable for harnessing geothermal energy. Icelanders have long used geothermal energy for direct applications, such as heating homes and baths. The more recent, widespread adoption of geothermal energy as an energy source in Iceland was spawned by a need to stabilize energy prices and increase energy independence, allowing Iceland to increase reliance on geothermal energy for direct applications alongside electricity generation and contributing significantly to diminishing Iceland's carbon footprint. The growth of geothermal power in Iceland is due to its continued support from the Icelandic government. As of 2020, Iceland’s installed geothermal power production capacity is 799 megawatts (MW). Geothermal energy produces over a quarter of Iceland's total electricity. Geology Iceland's territory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geothermal Heating
Geothermal heating is the direct use of geothermal energy for some heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004. As of 2007, 28 GW of geothermal heating capacity is installed around the world, satisfying 0.07% of global primary energy consumption. Thermal efficiency is high since no energy conversion is needed, but capacity factors tend to be low (around 20%) since the heat is mostly needed in the winter. Geothermal energy originates from the heat retained within the Earth since the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface. Most high temperature geothermal heat is harvested in regions close to tectonic plate boundaries where volcanic activity rises close to the surface of the Earth. In these areas, ground and groundwater can be found with temper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
