Geothermal Power In Australia
Geothermal power in Australia was at one time hoped to provide cost effect, renewable power for Australia. There are locations that have been shown to contain hot granites at depth which hold good potential for development of geothermal energy. Exploratory geothermal wells have been drilled to test for the presence of high temperature geothermal reservoir rocks and such hot granites were detected. However, all these projects have since been abandoned. A small geothermal plant in Queensland experienced problems during commissioning and as at May 2022, remains idle. Exploration Exploration involves finding vast blocks of " hot rocks" with fracture systems that could generate electricity through water being injected, circulated through the fractures, and being returned to surface as steam which could then be used to rotate steam turbines. There are vast deep-seated granite systems in Central Australia that have high temperatures at depth and these have been drilled by companies su ...

Base Load Power Plant
The base load (also baseload) is the minimum level of demand on an electrical grid over a span of time, for example, one week. This demand can be met by unvarying power plants, dispatchable generation, or by a collection of smaller intermittent energy sources, depending on which approach has the best mix of cost, availability and reliability in any particular market. The remainder of demand, varying throughout a day, is met by dispatchable generation which can be turned up or down quickly, such as load following power plants, peaking power plants, or energy storage. Power plants that do not change their power output quickly, such as large coal or nuclear plants, are generally called baseload power plants. Donald G. Fink, H. Wayne Beatty (ed), ''Standard Handbook for Electrical Engineers'', Eleventh Edition, Mc-Graw Hill, 1978 , pp. 12-16 through 12-18 Historically, most or all of base load demand was met with baseload power plants, whereas new capacity based around renewables ofte ...

Biofuel In Australia
Biofuel is fuel that is produced from organic matter ( biomass), including plant materials and animal waste. It is considered a renewable source of energy that can assist in reducing carbon emissions. The two main types of biofuel currently being produced in Australia are biodiesel and bioethanol, used as replacements for diesel and petrol (gasoline) respectively. As of 2017 Australia is a relatively small producer of biofuels, accounting for 0.2% of world bioethanol production and 0.1% of world biodiesel production. In 2016–17, biofuels contributed only 0.5% of the total liquid and gaseous transport fuel energy mix in Australia. Total commercial biofuel production for 2018 is estimated at 290 million liters (ML): 250ML of ethanol and 40ML of biodiesel. This article mainly deals with biofuels for personal vehicles, though cooking, heating and electricity generation can also use biofuel. Historically in Australia cooking and home heating have been accomplished by burning wood, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Power In Australia
Solar power in Australia is a fast growing industry. As of September 2022, Australia's over 3.27 million solar PV installations had a combined capacity of 28,177 MW photovoltaic (PV) solar power, of which at least 4,258 MW was installed in the preceding 12 months. In 2019, 59 solar PV projects with a combined capacity of 2,881 MW was either under construction, constructed or due to start construction having reached financial closure. Solar accounted for 9.9% (or 22.5 TWh) of Australia's total electrical energy production in 2020. The sudden rise in solar PV installations in Australia since 2018 dramatically propelled the country from being considered a relative laggard to a strong leader by mid-2019. With an installed photovoltaic capacity of 16.3 GW at the end of 2019, Australia had the second highest per capita solar capacity at 637 watts per capita. The installed PV capacity in Australia increased 10-fold between 2009 and 2011, and quadrupled between 2011 and 2016. The fi ...

Wind Power In Australia
Wind power is one of the main renewable energy sources in Australia contributing 10% of Australia's total electricity supply in 2020, and making up 37.5% of it's renewable energy supply. Wind resource testing conditions in Australia are optimum, as abundant wind resources may be located close to residential areas in the southern parts of the country and on the slopes of the Great Dividing Range in the east. As of the end of 2020, there was 7,376 megawatts (MW) of installed wind power capacity contributing 9.9% of generation to the electricity sector in Australia, and a further 4,021 MW of capacity was committed or under construction. Wind resources Australia has excellent wind resources by world standards. The southern coastline lies in the roaring forties and many sites have average wind speeds above 8 or even 9 m/s at turbine hub height. The southwest portion of Western Australia, south of South Australia, western Victoria, the north of Tasmania as well as elevated areas ...

Australian Renewable Energy Agency
The Australian Renewable Energy Agency (ARENA) is an independent agency of the Australian federal government, established in 2012 to manage Australia's renewable energy programs, with the objective of increasing supply and competitiveness of Australian renewable energy sources. Background ARENA was established in 2012 as an independent statutory authority to manage the government's renewable energy programs. Legal establishment came with the passing of the Australian Renewable Energy Agency Act 2011 (ARENA Act). The legislation passed parliament in November 2011 with the support of the Australian Greens and the Liberal and National coalition opposition as well as the governing Labor Party. ARENA commenced operations on 1 July 2012. The agency resulted from negotiations within the Australian parliament under the Gillard Government, with the intention of providing more secure funding for renewable energy programs in the context of political changes. While ARENA was created ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renewable Energy In Australia
Renewable energy in Australia includes wind power, hydroelectricity, solar PV, heat pumps, geothermal, wave and solar thermal energy. In 2021, Australia produced 74,679 gigawatt-hours of renewable energy, which accounted for 32.5% of electricity production. Australia produced 378.7 PJ of overall renewable energy (including renewable electricity) in 2016-17, which accounted for 6.2% of Australia's total energy use (6,146 PJ). Renewable energy grew by an annual average of 3.2% in the 10 years between 2007 and 2017, and by 5.2% between 2016 and 2017. This contrasts to growth in coal (1.9%), oil (1.7%) and gas (2.9%) over the same 10 year period. Similar to many other countries, development of renewable energy in Australia has been encouraged by government energy policy implemented in response to concerns about climate change, energy independence and economic stimulus.

Geothermal Desalination
Geothermal desalination refers to the process of using geothermal energy to power the process of converting salt water to fresh water. The process is considered economically efficient, and while overall environmental impact is uncertain, it has potential to be more environmentally friendly compared to conventional desalination options. Geothermal desalination plants have already been successful in various regions, and there is potential for further development to allow the process to be used in an increased number of water scarce regions. Process explanation Desalination is the process of removing minerals from seawater to convert it into fresh water. Desalination is divided into two categories in terms of processes: processes driven by thermal energy and processes driven by mechanical energy. Geothermal desalination uses geothermal energy as the thermal energy source to drive the desalination process. There are two types of geothermal desalination: direct and indirect. Direct ge ...

Organic Rankine Cycle
In thermal engineering, the Organic Rankine Cycle (ORC) is a type of thermodynamic cycle. It is a variation of the Rankine cycle named for its use of an organic, high-molecular-mass fluid whose vaporization temperature is lower than that of water. The fluid allows heat recovery from lower-temperature sources such as biomass combustion, industrial waste heat, geothermal heat, solar ponds etc. The low-temperature heat is converted into useful work, that can itself be converted into electricity. The technology was developed in the late 1950s by Lucien Bronicki and Harry Zvi Tabor.Harry Zvi Tabor Cleveland Cutler, , 2007.

Cooper Basin
The Cooper Basin is a Permian-Triassic sedimentary geological basin in Australia. The basin is located mainly in the southwestern part of Queensland and extends into northeastern South Australia. It is named after the Cooper Creek which is an ephemeral river that runs into Lake Eyre. For most of its extent, it is overlain by the Eromanga Basin. It covers 130,000 km². The surface of the Cooper Basin is mostly desert, including parts of the Simpson Desert, the Channel Country and Sturt Stony Desert. Oil and gas exploration of the basin began in 1962. Energy resources Oil and natural gas The Cooper Basin has the most important on-shore petroleum and natural gas deposits in Australia. The oil and gas window is located 1,250 m below the surface and was originally discovered in the 1960s (although there are larger oil and gas deposits off-shore). The first commercial discovery of gas occurred in 1963. It includes Australia's largest onshore oil field, the Jackson oil field. This ...

The Mercury (Hobart)
''The'' ''Mercury'' is a daily newspaper, published in Hobart, Tasmania, Australia, by Davies Brothers Pty Ltd (DBL), a subsidiary of News Corp Australia, itself a subsidiary of News Corp. The weekend issues of the paper are called ''Mercury on Saturday '' and ''Sunday Tasmanian''. The current editor of ''The'' ''Mercury'' is Craig Warhurst. History The newspaper was started on 5 July 1854 by George Auber Jones and John Davies. Two months subsequently (13 September 1854) John Davies became the sole owner. It was then published twice weekly and known as the ''Hobarton Mercury''. It rapidly expanded, absorbing its rivals, and became a daily newspaper in 1858 under the lengthy title ''The Hobart Town Daily Mercury''. In 1860 the masthead was reduced to ''The Mercury'' and in 2006 it was further shortened to simply ''Mercury''. With the imminent demise of the ( Launceston) ''Daily Telegraph'', ''The Mercury'', from March 1928, used the opportunity to increase their penetration th ...
