Renewable Energy In New Zealand
Approximately 40% of primary energy (Heat and power) is from renewable energy sources in New Zealand. Approximately 80% of electricity comes from renewable energy, primarily hydropower and geothermal power. Renewable energy by type Renewable electricity Renewable electricity in New Zealand is primarily from hydropower. In 2017, 82% of the electricity generated in New Zealand came from renewable sources. In September 2007, former Prime Minister Helen Clark announced a national target of 90 percent renewable electricity by 2025, with wind energy to make up much of that increase. Solar power Solar technologies in New Zealand only became affordable alternatives in the mid-2010s, compared to previous renewable offerings. The uptake in the residential and commercial market, though slow, has increased steadily. As with all renewable options, price of generation is key to the sustainability. It is only these recent changes in pricing that may see solar generation plants in the future. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood Processing
Wood processing is an engineering discipline in the wood industry comprising the production of forest products, such as pulp and paper, construction materials, and tall oil. Paper engineering is a subfield of wood processing. The major wood product categories are: sawn timber, wood-based panels, wood chips, paper and paper products and miscellaneous others including poles and railway sleepers. Forest product processing technologies have undergone extraordinary advances in some of the above categories. Improvements have been achieved in recovery rates, durability and protection, greater utilization of NTFPs such as various grain stalks and bamboo, and the development of new products such as reconstituted wood-panels. Progress has not been homogenous in all the forest product utilization categories. Although there is little information available on the subjects of technology acquisition, adaptation and innovation for the forest-based industrial sector, it is clear that sawmillin ...

Renewable Energy By Country
This is a list of renewable energy topics by country and territory. These links can be used to compare developments in renewable energy in different countries and territories and to help and encourage new writers to participate in writing about developments in their own countries or countries of interest. The list refers to renewable energy in general, as well as solar power, wind power, geothermal energy, biofuel, and hydro-electricity. As of 2013, China, Germany, and Japan, and India, four of the world's largest economies generate more electricity from renewables than from nuclear power. Based on REN21's 2014 report, renewables supplied 19% of humans' global energy consumption. This energy consumption is divided as 9% coming from traditional biomass, 4.2% as heat energy (non-biomass), 3.8% hydro electricity and 2% is electricity from wind, solar, geothermal, and biomass. China is the world's largest producer of hydroelectricity, followed by Canada, Brazil, India, U.S and Rus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Hot Water In New Zealand
Solar hot water in New Zealand is increasingly used on both new and existing buildings. Solar thermal technologies had a sizable initial uptake in the pioneering days of the 1970s. By 2001 more than 40GWhr was produced from solar hot water technologies, equating to 0.1% of the total electricity consumption in New Zealand. In 2006 the government announced an investment of $15.5 million over the first three and a half years of a five-year Solar Water Heating program to increase the number of solar hot water heating installations. As of 2006 there were about 35,000 solar hot water installations on domestic and commercial buildings. There are now eleven manufacturers and importers in the industry with most of the collector system being locally made. Barriers to adoption The main barrier for the installation of solar hot water systems is the initial capital investment. Other barriers are the conservatism of the building industry, lack of influence on increasing the sale price of hous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric Power In New Zealand
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Biofuel In New Zealand
There are a number of biofuels used in New Zealand. Biofuels Biodiesel Ecodiesel, a company owned by a group of New Zealand farmers, plans to build a biodiesel plant by the end of 2008. The plant will be built in stages and cheaper than Argent's, and could produce 20 million litres of tallow-based biodiesel per year by April 2009. In the effort to develop an aviation biofuel, Air New Zealand and Boeing are researching the jatropha plant to see if it can provide a renewable alternative to conventional fuel. Bioethanol Gull Force 10, a bioethanol blend, was introduced commercially in New Zealand for the first time by the company Gull on 1 August 2007. It contained 10% ethanol made from dairy by product by Anchor Ethanol, a subsidiary of Fonterra Ltd. On 8 August 2008, Gull introduced a 91-octane bioethanol blend in Albany. The blend, 'regular plus', contained 10% ethanol and included bioethanol made from whey. Gull planned to release the fuel to 33 stations, and marketed it a ...

Ocean Power In New Zealand
New Zealand has large ocean energy resources but does not yet generate any power from them. TVNZ reported in 2007 that over 20 wave and tidal power projects are currently under development. However, not a lot of public information is available about these projects. The Aotearoa Wave and Tidal Energy Association was established in 2006 to "promote the uptake of marine energy in New Zealand". According to their 10 February 2008 newsletter, they have 59 members. However, the association doesn't list its members. From 2008 to 2011, the government Energy Efficiency and Conservation Authority is allocating $2 million each year from a Marine Energy Deployment Fund, set up to encourage the utilisation of this resource. The greater Cook Strait and Kaipara Harbour seem to offer the most promising sites for using underwater turbines. Two resource consents have been granted for pilot projects in Cook Strait itself and in the Tory Channel, and consent is being sought for a project sites at th ...

Wind Power In New Zealand
Wind power constitutes a small but growing proportion of New Zealand's electricity. As of December 2020, wind power accounts for 690 MW of installed capacity and over 5 percent of electricity generated in the country. New Zealand has abundant wind resources. The country is in the path of the Roaring Forties, strong and constant westerly winds, and the funneling effect of Cook Strait and the Manawatu Gorge increase the resource's potential. Over three-quarters (512 MW) of the country's wind generation is installed within a radius of Palmerston North, with some turbines in the area having a capacity factor of over 50 percent. Generation capacity and expansion As of December 2020, New Zealand had an installed wind generation capacity of 690 MW. In the 2020 calendar year, wind power produced 2,282 GWh of electricity, 5.5 percent of the country's electricity generation that year. A further 2,500 MW of wind farms have received resource consent. The New Zeal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Power In New Zealand
Solar power in New Zealand is increasing in capacity, despite no government subsidies or interventions being available. As at the end of December 2022, New Zealand has 255 MW of grid-connected photovoltaic (PV) solar power installed, of which 65 MW (25%) was installed that year. In the 12 months to September 2022, 249 gigawatt-hours of electricity was estimated to have been generated by grid-connected solar, 0.57% of all electricity generated in the country. Although there are no subsidies, the declining costs of photovoltaics has caused a large increase in demand over the last few years. In 2009, the average turnkey price for a standard PV system of three kilowatts (kW) was about NZ$40,000; by 2019 this had dropped to approx. NZ$8,500. Distributed systems As of the end of December 2022, 45,761 solar power systems had been installed in New Zealand. For new installations added in December 2022, the average residential system size was 5.7 kW and the average commerci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renewable Energy Commercialisation
Renewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years. First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy. Third-generation technologies require continued R&D efforts in order to make large contributions on a global scale and include advanced biomass gasification, hot-dry-rock geothermal power, and ocean energy.International Energy Agency (2007)''Renewables in global energy supply: An IEA facts sheet'' (PDF)OECD, 34 pages. As of 2012, renewable energy accounts for about half of new nameplate electrical capacity installed and costs are continuing to fall. Public policy and political l ...

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 percent of primary energy supply coming from hydrocarbon fuels. This ratio decreased to about 60 percent 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 by 33 ...
