Krafla Geothermal Power Station
The Krafla geothermal power plant ( ) is a geothermal power generating facility located in Iceland, close to the Krafla, Krafla Volcano and the lake Mývatn. With 33 boreholes, it is able to produce 500 GWh of electricity annually, with an installed capacity of 60 megawatts. The construction work started in 1974, but due to volcanic activities in the area, building was slowed. The Krafla power station was officially launched in the early 1977, but was only able to produce at its full 60-megawatt capacity after a second steam turbine was installed in 1996. Originally the power plant was owned by the government, but was purchased in 1985 and has since been operated by Landsvirkjun (National Power Company). About 15 employees work there full-time. Geothermal power station details The Krafla geothermal power plant consists of two 30-megawatt units, with double pressure inlet and dual-flow turbines with 5 steps on each side.

Sustainable Energy
Energy system, Energy is sustainability, sustainable if it "meets the needs of the present without compromising the ability of future generations to meet their own needs." Definitions of sustainable energy usually look at its effects on the environment, the economy, and society. These impacts range from greenhouse gas emissions and air pollution to energy poverty and toxic waste. Renewable energy sources such as wind power, wind, Hydroelectricity, hydro, solar energy, solar, and geothermal energy can cause environmental damage but are generally far more sustainable than fossil fuel sources. The role of Non-renewable resource, non-renewable energy sources in sustainable energy is controversial. Nuclear power does Low-carbon power, not produce carbon pollution or air pollution, but has drawbacks that include radioactive waste, the risk of nuclear proliferation, and the Nuclear and radiation accidents and incidents, risk of accidents. Switching from coal to natural gas has enviro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subsidence
Subsidence is a general term for downward vertical movement of the Earth's surface, which can be caused by both natural processes and human activities. Subsidence involves little or no horizontal movement, which distinguishes it from slope movement. Processes that lead to subsidence include dissolution of underlying carbonate rock by groundwater; gradual compaction of sediments; withdrawal of fluid lava from beneath a solidified crust of rock; mining; pumping of subsurface fluids, such as groundwater or petroleum; or warping of the Earth's crust by tectonic forces. Subsidence resulting from tectonic deformation of the crust is known as tectonic subsidence and can create accommodation for sediments to accumulate and eventually lithify into sedimentary rock. Ground subsidence is of global concern to geologists, geotechnical engineers, surveyors, engineers, urban planners, landowners, and the public in general.National Research Council, 1991.

Wairakei Power Station
The Wairakei Power Station is a geothermal power station near the Wairakei Geothermal Field in New Zealand. Wairakei lies in the Taupō Volcanic Zone. History The power station was built in 1958, the first of its type (wet steam) in the world, and it is currently owned and operated by Contact Energy. A binary cycle power plant was constructed in 2005 to use lower-temperature steam that had already gone through the main plant. This increased the total capacity of the power station to 181 MW. The Wairakei power station is due to be phased out in 2027, replaced by the Te Mihi Power Station, Te Mihi geothermal power station. The Poihipi Power Station was built in 1996 at a nearby site in the same field.

The Geysers
The Geysers is the world's largest geothermal field, containing a complex of 18 geothermal power plants, drawing steam from more than 350 wells, located in the Mayacamas Mountains approximately north of San Francisco, California. Geysers produced about 20% of California's renewable energy in 2019. Calpine, the largest generator of electricity from natural gas and geothermal resources in the US, generates power at the site. History For about 12,000 years, Native Americans built steam baths and thermal pools at The Geysers and used the steam and hot water for healing purposes, as well as spiritual and ceremonial practices, and cooking. The thermal pools were used as a medicinal treatment for rheumatism and arthritis. The heated mud was used to soothe skin rashes and other aches and pains, using the fumaroles as a natural energy source. When European Americans first arrived, six local native tribes inhabited the area around The Geysers. These tribes included three bands of Pomo p ...

Larderello
Larderello is a ''frazione'' of the ''comune'' of Pomarance, in Tuscany in central Italy, renowned for its geothermal productivity. Geography The region of Larderello has experienced occasional phreatic eruptions, caused by explosive outbursts of steam trapped below the surface. The water is contained in metamorphic rocks where it is turned to steam which is then trapped beneath a dome of impermeable shales and clay. The steam escapes through faults in the dome and forces its way out in the hot springs. It possesses a dozen explosion craters 30–250 m in diameter. The largest is the Lago Vecchienna crater which last erupted around 1282, now filled by the Boracifero Lake. Larderello now produces 10% of the world's entire supply of geothermal electricity, amounting to 4,800 GWh per year and powering about a million Italian households. Its geology makes it uniquely conducive to geothermal power production, with hot granite rocks lying unusually close to the surface, prod ...

Piero Ginori Conti, Prince of Trevignano, (Florence, 3 June 1865 – Florence, 3 December 1939) was a businessman and Italian politician. He was the son of Gino Ginori Conti and Pauline Fabbri, an old aristocratic family of Florence. In 1894, Piero Ginori Conti married Adriana de Larderel (1872–1925), daughter of Count Florestan and Marcella de Larderel (who was Piero's cousin), and heir to one of the most significant fortunes in Tuscany. Geothermal electricity and Boric Acid In 1904, Piero Ginori Conti became the head of the boric acid extraction firm founded by his wife's great-grandfather in Larderello, and took the establishment in a new direction, with the use of natural steam to produce electricity. His business plan was: improving the quality of products, increasing production and lowering prices, and exploiting natural dry steam geysers to produce electricity. On 4 July 1904, at Larderello, Conti powered five bulbs from a dynamo driven by a reciprocating steam engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incentive
In general, incentives are anything that persuade a person or organization to alter their behavior to produce the desired outcome. The laws of economists and of behavior state that higher incentives amount to greater levels of effort and therefore higher levels of performance. For comparison, a disincentive is something that discourages from certain actions. Divisions An incentive is a powerful tool to influence certain desired behaviors or action often adopted by governments and businesses. Incentives can be broadly broken down into two categories: intrinsic incentives and extrinsic incentives. Overall, both types of incentives can be powerful tools often employ to increase effort and higher performance according to the "law of behavior." Incentives are most studied in the area of personnel economics where economic analysts, such as those who take part in human resources management practices, focus on how firms make employees more motivated, through pay and career concerns, Fi ...

Carbon Dioxide
Carbon dioxide is a chemical compound with the chemical formula . It is made up of molecules that each have one carbon atom covalent bond, covalently double bonded to two oxygen atoms. It is found in a gas state at room temperature and at normally-encountered concentrations it is odorless. As the source of carbon in the carbon cycle, atmospheric is the primary carbon source for life on Earth. In the air, carbon dioxide is transparent to visible light but absorbs infrared, infrared radiation, acting as a greenhouse gas. Carbon dioxide is soluble in water and is found in groundwater, lakes, ice caps, and seawater. It is a trace gas Carbon dioxide in Earth's atmosphere, in Earth's atmosphere at 421 parts per million (ppm), or about 0.042% (as of May 2022) having risen from pre-industrial levels of 280 ppm or about 0.028%. Burning fossil fuels is the main cause of these increased concentrations, which are the primary cause of climate change.IPCC (2022Summary for pol ...
