Renewable Energy In Guyana
The electricity sector in Guyana is dominated by Guyana Power and Light (GPL), the state-owned vertically integrated utility. Although the country has a large potential for hydroelectric and bagasse-fueled power generation, most of its 226 MW of installed capacity correspond to thermoelectric diesel-engine driven generators. Reliability or electricity supply is very low, linked both to technical and institutional deficiencies in the sector, with total losses close to 40% and commercial losses of about 30%. This low reliability has led most firms to install their own diesel generators, which in turn leads to higher than average electricity costs. Electricity supply and demand Installed power generation capacity in Guyana in 2007 was 226 MW or 0.4 kW per capita, which is lower than in other countries in the region and is hardly sufficient to cover the current demand for electricity in the country. Most electricity generation uses Diesel engines to drive generators. There a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electricity Generation
Electricity generation is the process of generating electric power from sources of primary energy. For electric utility, utilities in the electric power industry, it is the stage prior to its Electricity delivery, delivery (Electric power transmission, transmission, Electric power distribution, distribution, etc.) to end users or its Grid energy storage, storage (using, for example, the Pumped-storage hydroelectricity, pumped-storage method). Electricity is not freely available in nature, so it must be "produced" (that is, transforming other forms of energy to electricity). Production is carried out in power stations (also called "power plants"). Electricity is most often generated at a power plant by electromechanical electric generator, generators, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power. There are al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economy Of Guyana
The economy of Guyana is one of the fastest growing in the world with a gross domestic product (GDP) growth of 19.9% in 2021. In 2022, Guyana had a per capita gross domestic product of $42,647 and an average GDP growth of 4.2% over the previous decade. Guyana's economy was transformed in 2015 with the discovery of an offshore oil field in the country’s waters about 120 miles from Georgetown. Crude oil production started in 2019. Overview Developed in conjunction with the World Bank and the International Monetary Fund (IMF), an economic recovery program significantly reduced the government's role in the economy, encouraged foreign investment, enabled the government to clear all its arrears on loan repayments to foreign governments and the multilateral banks, and brought about the sale of 15 of the 41 government-owned (parastatal) businesses. The cellphone company and assets in the timber, rice, and fishing industries also were privatized. International corporations were hired to ...

Guyana
Guyana ( or ), officially the Cooperative Republic of Guyana, is a country on the northern mainland of South America. Guyana is an indigenous word which means "Land of Many Waters". The capital city is Georgetown. Guyana is bordered by the Atlantic Ocean to the north, Brazil to the south and southwest, Venezuela to the west, and Suriname to the east. With , Guyana is the third-smallest sovereign state by area in mainland South America after Uruguay and Suriname, and is the second-least populous sovereign state in South America after Suriname; it is also one of the least densely populated countries on Earth. It has a wide variety of natural habitats and very high biodiversity. The region known as "the Guianas" consists of the large shield landmass north of the Amazon River and east of the Orinoco River known as the "land of many waters". Nine indigenous tribes reside in Guyana: the Wai Wai, Macushi, Patamona, Lokono, Kalina, Wapishana, Pemon, Akawaio and Warao. Histo ...

Weighted Mean
The weighted arithmetic mean is similar to an ordinary arithmetic mean (the most common type of average), except that instead of each of the data points contributing equally to the final average, some data points contribute more than others. The notion of weighted mean plays a role in descriptive statistics and also occurs in a more general form in several other areas of mathematics. If all the weights are equal, then the weighted mean is the same as the arithmetic mean. While weighted means generally behave in a similar fashion to arithmetic means, they do have a few counterintuitive properties, as captured for instance in Simpson's paradox. Examples Basic example Given two school with 20 students, one with 30 test grades in each class as follows: :Morning class = :Afternoon class = The mean for the morning class is 80 and the mean of the afternoon class is 90. The unweighted mean of the two means is 85. However, this does not account for the difference in number of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Power
Wind power or wind energy is mostly the use of wind turbines to electricity generation, generate electricity. Wind power is a popular, sustainable energy, sustainable, renewable energy source that has a much smaller Environmental impact of wind power, impact on the environment than burning fossil fuels. Historically, wind power has been used in sails, windmills and windpumps but today it is mostly used to generate electricity. Wind farms consist of many individual wind turbines, which are connected to the electric power transmission Electrical grid, network. New Onshore wind farm, onshore (on-land) wind farms are cheaper than new Coal-fired power station, coal or Gas-fired power plant, gas plants, but expansion of wind power is being hindered by fossil fuel subsidies.

Power Purchase Agreement
A power purchase agreement (PPA), or electricity power agreement, is a contract between two parties, one which generates electricity (the seller) and one which is looking to purchase electricity (the buyer). The PPA defines all of the commercial terms for the sale of electricity between the two parties, including when the project will begin commercial operation, schedule for delivery of electricity, penalties for under delivery, payment terms, and termination. A PPA is the principal agreement that defines the revenue and credit quality of a generating project and is thus a key instrument of project finance. There are many forms of PPA in use today and they vary according to the needs of buyer, seller, and financing counter parties. Contractual terms of a PPA may last anywhere between 5 and 20 years, during which time the power purchaser buys energy, and sometimes also capacity and/or ancillary services, from the electricity generator. Such agreements play a key role in the financin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guyana Sugar Corporation
The Guyana Sugar Corporation, or GuySuCo, is a Guyanese sugar company owned by the government. It is the country's largest cultivator and producer of sugar, a historically important commodity in the country. They produce Demerara Sugar for export around the world. History The company was formed in 1976, when the government of Guyana nationalised and merged the sugar estates operated by Booker Sugar Estates Limited, Tate and Lyle and Jessels Holdings to form the Guyana Sugar Corporation. GuySuCo initially lacked needed experience and lacked the reserves of foreign capital required to maintain sugar plantations and processing mills during economically difficult periods. When production fell, GuySuCo became increasingly dependent on state support to pay the salaries of its 20,000 workers. During this time, the industry was hard-hit by labor unrest directed at the government of Guyana. A four-week strike in early 1988 and a seven-week strike in 1989 contributed to the low harvests. ...

Greenhouse Gas Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely followed by ...

Bagasse
Bagasse ( ) is the dry pulpy fibrous material that remains after crushing sugarcane or sorghum stalks to extract their juice. It is used as a biofuel for the production of heat, energy, and electricity, and in the manufacture of pulp and building materials. Agave bagasse is similar, but is the material remnants after extracting blue agave sap. Etymology The word comes from ''bagage'' (French) and ''bagazo'' (Spanish), meaning ''refuse'' or ''trash''. It originally referred to the material left after pressing olives, palm nuts, and grapes. The word eventually came to be used in the context of processing of plants such as sugarcane and sugar beets. Today, it usually refers to by-products of the sugarcane mill. Description Bagasse is the solid by-product when the liquid components are extracted from plants. Much of the core of those plants is a heterogeneous "pith" fibre. This fibre is primarily parenchyma tissue, along with bast, rind, or stem fibers of the sclerenchyma. Here's an ...

Kuribrong River
The Kuribrong River is a river of Guyana, a tributary of the Potaro River 2 miles north east of Potaro Landing. The Kuribrong is a part of the Essequibo River basin, and supports endemic fish species. The geological make up of the river is schistose quartz-porphyrite and sericite schist, and quartz boulders making up any major river obstruction. The river was deemed to be of low interest for gold mining, to contrast with other rivers of the region. Economic use There is a settlement at "Kuribrong River, Mona Falls" with a population of 28 in the 2012 census. It was considered for a now-defunct hydroelectric project, at the confluence with the Amaila River. Balata bleeding was once done in the area of the river.
