Energy In New Zealand
Despite abundant natural resources and a relatively small population, New Zealand is a net importer of energy, in the form of petroleum products. The ratio of non-renewable and renewable energy sources was fairly consistent from 1975 to 2008, with about 70 per cent of primary energy supply coming from hydrocarbon fuels. This ratio decreased to about 60 per cent in 2018. The proportion of non-renewable energy varies annually, depending on water flows into hydro-electricity lakes and demand for energy. In 2018, approximately 60% of primary energy was from non-renewable hydrocarbon fuels and 40% was from renewable sources. In 2007 energy consumption per capita was 120 gigajoules. Per capita energy consumption had increased 8 per cent since 1998. New Zealand uses more energy per capita than 17 of 30 OECD countries. New Zealand is one of 13 OECD countries that does not operate nuclear power stations. From 1994 to 2018, the energy intensity of the economy per unit of GDP declined b ...

Petajoules
The joule ( , or ; symbol: J) is the unit of energy in the International System of Units (SI). In terms of SI base units, one joule corresponds to one kilogram- metre squared per second squared One joule is equal to the amount of work done when a force of one newton displaces a body through a distance of one metre in the direction of that force. It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889). Definition According to the International Bureau of Weights and Measures the joule is defined as "the work done when the point of application of 1 MKS unit of force ewtonmoves a distance of 1 metre in the direction of the force." In terms of SI base units and in terms of SI derived units with special names, the joule is defined as One joule is also equivalent to any of the following: * The work required to move an e ...

International Energy Agency
The International Energy Agency (IEA) is a Paris-based autonomous intergovernmental organization, established in 1974, that provides policy recommendations, analysis and data on the global energy sector. The 31 member countries and 13 association countries of the IEA represent 75% of global energy demand. The IEA was set up under the framework of the Organisation for Economic Co-operation and Development (OECD) in the aftermath of the 1973 oil crisis to respond to physical disruptions in global oil supplies, provide data and statistics about the global Petroleum industry, oil market and Energy industry, energy sector, promote energy savings and conservation, and establish international technical collaboration. Since its founding, the IEA has also coordinated use of the oil reserves that its members are required to hold. By regularly underestimating the role of renewable energies and overestimating the growth of nuclear energy, the IEA promotes the nuclear industry. In subsequen ...

Natural Gas
Natural gas (also fossil gas, methane gas, and gas) is a naturally occurring compound of gaseous hydrocarbons, primarily methane (95%), small amounts of higher alkanes, and traces of carbon dioxide and nitrogen, hydrogen sulfide and helium. Methane is a colorless and odorless gas, and, after carbon dioxide, is the second-greatest greenhouse gas that contributes to global climate change. Because natural gas is odorless, a commercial odorizer, such as Methanethiol (mercaptan brand), that smells of hydrogen sulfide (rotten eggs) is added to the gas for the ready detection of gas leaks. Natural gas is a fossil fuel that is formed when layers of organic matter (primarily marine microorganisms) are thermally decomposed under oxygen-free conditions, subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other ...

Great South Basin
The Great South Basin is an area of mainly sea to the south of the South Island of New Zealand. Starting in the 1960s, the area was explored and drilled for oil deposits by various, mostly international minerals companies — including Hunt Oil — but by 1984 all of these companies had left empty-handed. With advances in seismic surveying and drilling technology, hopes have been raised once again for a potential oil strike. Since 2006, new tenders for drilling rights have been issued. In 2010, ExxonMobil Exxon Mobil Corporation ( ) is an American multinational List of oil exploration and production companies, oil and gas corporation headquartered in Spring, Texas, a suburb of Houston. Founded as the Successors of Standard Oil, largest direct s ... and Todd Energy relinquished their exploration rights, citing technical difficulties and the harshness of the environment.

Kupe Field
The Kupe natural gas field is located in the Tasman Sea, 30 km off the coast of the town of Manaia in Taranaki, New Zealand. The field was discovered in 1986 and is located in 35 metres of water. The production facility comprises an unmanned offshore platform, a 30 km single three phase pipeline to shore and an onshore production station. Total recoverable reserves are 437 PJ of gas and LPG and of oil and condensate. Development project Project development was led by Technip and the total project cost NZ$1.3b. The first export gas was produced in December 2009. The project was officially opened by Prime Minister John Key on 18 March 2010. Production facility The facility is owned by a joint venture comprising; * Beach Energy (South Australia) (50%), * Genesis Energy (46%), * New Zealand Oil and Gas (4%). At its peak, the gas produced from the Kupe field is expected to meet 10 to 15 per cent of New Zealand's annual gas demand and 50 per cent of New Zealand's LPG dem ...

Maui Gas Field
The Maui natural gas field is the largest gas, natural gas condensate and oil field in New Zealand, producing nearly three-quarters of the country's hydrocarbons, as well as providing energy for electricity generation. It is located in the Tasman Sea, 35 km off the coast of Taranaki Region, Taranaki and to the southwest of New Plymouth. It covers an area of 157 square kilometres and is located in 110 metres of water. The gas field was discovered in 1969 by a joint venture of Royal Dutch Shell, Royal Dutch/Shell, BP, British Petroleum and Todd Corporation, Todd Petroleum. It was considered a "giant" field at the time of discovery. Government investment led to a government organisation later called Petrocorp taking a 50% interest. This was later bought out by Fletcher Challenge Energy. By the end of the Maui gas contract in 2009, the Maui Mining Companies were made up of Shell Oil Company, Shell (83.75%), OMV New Zealand (10%), and Todd Energy (6.25%). OMV New Zealand owns a ...

Kapuni
Kapuni is an onshore natural gas-condensate field located in the Taranaki Basin, a ~100,000 km2 partially-inverted rift basin on the Taranaki Peninsula in the North Island, New Zealand. Discovered in 1959 and brought into production in 1970, Kapuni remained New Zealand's only producing gas-condensate field until the offshore Maui gas field began production in 1979. Geology Geologic history During the Lower Cretaceous (~150–100 Ma) Rangitata Orogeny, an accretionary wedge accumulated and was uplifted on the margin of Gondwana in present-day New Zealand. The resulting topography was eroded throughout the Cretaceous. After the Rangitata Orogeny, seafloor spreading commenced during the Middle Cretaceous. This resulted in the formation of the Tasman Sea as New Zealand separated from Australia. Normal faults, including the Manaia Fault, formed as the Taranaki Basin developed during seafloor spreading. Rifting continued until the Eocene (~56 Ma), when the Taranaki Basin und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand Government
The New Zealand Government () is the central government through which political authority is exercised in New Zealand. As in most other parliamentary democracies, the term "Government" refers chiefly to the executive branch, and more specifically to the Ministry (collective executive), collective ministry directing the executive. Based on the principle of responsible government, it operates within the framework that "the reigns, but the government rules, so long as it has the support of the New Zealand House of Representatives, House of Representatives".Sir Kenneth Keith, quoted in the Cabinet Manual'. The ''Cabinet Manual (New Zealand), Cabinet Manual'' describes the main laws, rules and Constitutional convention (political custom), conventions affecting the conduct and operation of the Government. Executive power is exercised by Ministers in the New Zealand Government, ministers, all of whom are sworn into the Executive Council of New Zealand, Executive Council and accounta ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its Electricity generation, electricity.
