Cotingo River
The Cotingo River () is a river of Roraima state in northern Brazil, a tributary of the Surumu River. It flows through the Raposa Serra do Sol indigenous territory. For many years there has been discussion over building a major hydroelectric power project on the river. River basin The Cotingo River has its headwaters at the foot of Mount Roraima in the Guayana Highlands region. The upper part of the Cotingo River basin is contained in the Monte Roraima National Park, a protected area created in 1989 that is fully contained in the Raposa Serra do Sol indigenous territory. The river runs for about to its confluence with the Surumu River, of which is the main tributary. It contains continuous stretches of rapids and waterfalls. The savanna region of the river basin has an equatorial climate with tropical monsoon rainfall.

Roraima
Roraima ( ) is one of the 26 states of Brazil. Located in the country's North Region, it is the northernmost and most geographically and logistically isolated state in Brazil. It is bordered by the state of Pará to the southeast, Amazonas to the south and west, Venezuela to the north and northwest, and Guyana to the east. The state covers an area of approximately , slightly larger than Belarus, being the fourteenth largest Brazilian state by area. The city of Boa Vista is the capital and largest city in the state, and is the only capital in the country located entirely in the Northern Hemisphere. Antônio Denarium, a member of the conservative Progressistas party, has been the governor of the state since 2019. Roraima is the least populous state in Brazil, with an estimated population of 631,181 inhabitants as of 2020. It is also the state with the lowest population density in Brazil, with 2.01 inhabitants per square kilometre. Its economy, based mainly on the tertiar ...

Solar Power
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics (PV) were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar panels has fallen, grid-connected solar PV systems' capacity and production has doubled about every three years. Three-quarters of new generation capacity is solar, with both millions of rooftop installatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Power
Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely using wind turbines, generally grouped into wind farms and connected to the electrical grid. In 2024, wind supplied over 2,494 TWh of electricity, which was 8.1% of world electricity. With about 100 Gigawatt, GW added during 2021, mostly Wind power in China, in China and the Wind power in the United States, United States, global installed wind power capacity exceeded 800 GW. 30 countries generated more than a tenth of their electricity from wind power in 2024 and wind generation has nearly tripled since 2015. To help meet the Paris Agreement goals to Climate change mitigation, limit climate change, analysts say it should expand much faster – by over 1% of electricity generation p ...

Branco River
The Branco River (; Engl: ''White River'') is the principal affluent of the Rio Negro from the north. Basin The river drains the Guayanan Highlands moist forests ecoregion. It is enriched by many streams from the Tepui highlands which separate Venezuela and Guyana from Brazil. Its two upper main tributaries are the Uraricoera and the Takutu. The latter almost links its sources with those of the Essequibo; during floods headwaters of the Branco and those of the Essequibo are connected, allowing a level of exchange in the aquatic fauna (such as fish) between the two systems. The Branco flows nearly south, and finds its way into the Negro through several channels and a chain of lagoons similar to those of the latter river. It is long, up to its Uraricoera confluence. It has numerous islands, and, above its mouth, it is broken by a bad series of rapids. Discharge Average, minimum and maximum discharge of the Branco River at near mouth. Period from 1998 to 2022.

Ecotourism
Ecotourism is a form of nature-oriented tourism intended to contribute to the Ecological conservation, conservation of the natural environment, generally defined as being minimally impactful, and including providing both contributions to conservation and environmental education. The definition sometimes also includes being financially beneficial to the host community or making conservation financially possible. There are a range of different definitions, and the correct definition of the term was an active subject of debate as of 2009. The term is also used more widely by many organizations offering nature tourism, which do not focus on being beneficial to the environment. Since the 1980s, ecotourism has been considered an important endeavor by environmentalists for conservation reasons. Organizations focusing on ecotourism often make direct or indirect contributions to conservation or employ practices or technology that reduce impacts on the environment. However (according to Bu ...

Hoary-throated Spinetail
The hoary-throated spinetail (''Synallaxis kollari'') is a Critically Endangered bird species in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Brazil and Guyana.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, G. Del-Rio, A. Jaramillo, D. F. Lane, M. B. Robbins, F. G. Stiles, and K. J. Zimmer.

In the early twentieth century some authors moved it into the newly created genus ''Poecilurus''. By 2000 the merger of ''Poecilurus'' into ''Synallaxis'' was generally accepted and a study published in 2011 confirmed that placement. That study also established that the hoary-throated spinetail is a sister species to the white-whiskered spinetail (''S. candei'') and ...

Sun Parakeet
The sun conure (''Aratinga solstitialis''), also known as the sun parakeet, is a medium-sized, vibrantly colored parrot native to northeastern South America. The adult male and female are similar in appearance, with black beaks, predominantly golden-yellow plumage, orange-flushed underparts and face, and green and blue-tipped wings and tails. Sun conures are very social birds, typically living in flocks. They form monogamous pairs for reproduction, and nest in palm cavities in the tropics. Sun conures mainly feed on fruits, flowers, berries, blossoms, seeds, nuts, and insects. Conures are commonly bred and kept in aviculture and may live up to 30 years. This species is currently threatened by loss of habitat and trapping for plumage or the pet trade. Sun conures are now listed as endangered by the International Union for Conservation of Nature. Taxonomy The sun conure was one of the many species originally described by Carl Linnaeus in his landmark 1758 10th edition of ''System ...
