Omo River (Ethiopia)
The Omo River (also called Omo-Bottego) in southern Ethiopia is the largest Ethiopian river outside the Nile Basin. Its course is entirely contained within the boundaries of Ethiopia, and it empties into Lake Turkana on the border with Kenya. The river is the principal stream of an endorheic drainage basin, the Turkana Basin. The river basin is famous for its large number of early hominid fossils and archeological findings such as early stone tools, leading to its inclusion on the UNESCO World Heritage List in 1980. Geography The Omo River forms through the confluence of the Gibe River, by far the largest total tributary of the Omo River, and the Wabe River, the largest left-bank tributary of the Omo at . Given their sizes, lengths and courses one might consider both the Omo and the Gibe rivers to be one and the same river but with different names. Consequently, the whole river basin is sometimes called the ''Omo-Gibe River Basin''. This river basin includes part of the wester ...

Meles Zenawi
Meles Zenawi Asres (Tigrinya and ; , born Legesse Zenawi Asres; 9 May 1955 – 20 August 2012) was an Ethiopian soldier and politician who served as President of Ethiopia from 1991 to 1995 and then Prime Minister of Ethiopia from 1995 until his death in 2012. Born in Adwa to an Ethiopian father and an Eritrean mother, Meles became actively involved in politics after changing his original first name from Legesse to Meles, adopted following the execution of fellow university student Meles Takele by the Derg government in 1975. Shortly that year, he left Haile Selassie I University to join the Tigray People's Liberation Front (TPLF) and fight against the Derg (the Mengistu Haile Mariam-led military dictatorship in Ethiopia). In 1989, he became the chairman of the TPLF, and the head of the Ethiopian People's Revolutionary Democratic Front (EPRDF) after its formation in 1988. After leading the EPRDF to victory in the Ethiopian Civil War, he served as president of the Transitional Go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brownout (electricity)
A brownout is a drop in voltage in an electrical power supply system. Unintentional brownouts can be caused by excessive electricity demand, severe weather events, or a malfunction or error affecting electrical grid control or monitoring systems. Intentional brownouts are used for load reduction in an emergency, or to prevent a total grid power outage due to high demand. The term ''brownout'' comes from the dimming of incandescent lighting when voltage reduces. In some countries, the term ''brownout'' refers not to a drop in voltage but to an intentional or unintentional power outage (or blackout). Effects Different types of electrical apparatus will react in different ways to a voltage reduction. Some devices will be severely affected, while others may not be affected at all. Resistive loads The heat output of any resistive device, such as an electric space heater, is equal to the power consumption, which is directly proportional to the square of the applied voltage if ...

World Bank
The World Bank is an international financial institution that provides loans and grants to the governments of low- and middle-income countries for the purpose of pursuing capital projects. The World Bank is the collective name for the International Bank for Reconstruction and Development (IBRD) and International Development Association (IDA), two of five international organizations owned by the World Bank Group. It was established along with the International Monetary Fund at the 1944 Bretton Woods Conference. After a slow start, its first loan was to France in 1947. In the 1970s, it focused on loans to developing world countries, shifting away from that mission in the 1980s. For the last 30 years, it has included NGOs and environmental groups in its loan portfolio. Its loan strategy is influenced by the Sustainable Development Goals as well as environmental and social safeguards. , the World Bank is run by a president and 25 executive directors, as well as 29 various vice ...

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] |
Djibouti
Djibouti, ar, جيبوتي ', french: link=no, Djibouti, so, Jabuuti officially the Republic of Djibouti, is a country in the Horn of Africa, bordered by Somalia to the south, Ethiopia to the southwest, Eritrea in the north, and the Red Sea and the Gulf of Aden to the east. The country has an area of . In antiquity, the territory, together with Ethiopia, Eritrea and Somaliland, was part of the Land of Punt. Nearby Zeila, now in Somaliland, was the seat of the medieval Adal and Ifat Sultanates. In the late 19th century, the colony of French Somaliland was established following treaties signed by the ruling Dir Somali sultans with the French, and its railroad to Dire Dawa (and later Addis Ababa) allowed it to quickly supersede Zeila as the port for southern Ethiopia and the Ogaden. It was renamed the French Territory of the Afars and the Issas in 1967. A decade later, the Djiboutian people voted for independence. This officially marked the establishment of the ''Rep ...

Dispatchable Generation
Dispatchable generation refers to sources of electricity that can be programmed ''on demand'' at the request of power grid operators, according to market needs. Dispatchable generators may adjust their power output according to an order. Non-dispatchable renewable energy sources such as wind power and solar photovoltaic (PV) power cannot be controlled by operators. Other types of renewable energy that are dispatchable without separate energy storage are hydroelectric, biomass, geothermal and ocean thermal energy conversion. Startup time Dispatchable plants have varying startup times. The fastest plants to dispatch are grid batteries which can dispatch in milliseconds. Hydroelectric power plants can often dispatch in tens of seconds to minutes and natural gas power plants can generally dispatch in tens of minutes. For example, the 1,728 MW Dinorwig pumped storage power plant can reach full output in 16 seconds. Gas turbine (Brayton cycle) thermal plants require around 15 ...

Renewable Energy
Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy often provides energy for electricity generation to a grid, air and water heating/cooling, and stand-alone power systems. Renewable energy technology projects are typically large-scale, but they are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. Renewable energy is often deployed together with further electrification, which has several benefits: electricity can move heat or objects efficiently, and is clean at the point of consumption. In addition, electrification with renewable energy is more efficient and therefore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy In Ethiopia
Energy in Ethiopia is energy and electricity production, consumption, transport, exportation, and importation in Ethiopia. Overview The following table provides some of the most relevant energy sector numbers for Ethiopia, a developing country. The ''primary energy sector'' is by far the most important one in Ethiopia, with mainly wood used for cooking. That together with the population growth in Ethiopia results in issues like deforestation. Ethiopia aims at economic development and removal of poverty and to replace the use of wood by alternatives. This makes the ''secondary energy sector'' (with ''electricity'') most relevant for these efforts. Almost all recent developments are taking place in the secondary energy sector, with the construction of mainly hydropower plants and power transmission lines being most visible. * PE: Ethiopia did not export PE in the years shown. * PE: all PE imports were ''bituminous materials'' (natural asphalt used as engineering material for the ...

Electrical Generator
In electricity generation, a generator is a device that converts motive power (mechanical energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. In addition to electromechanical designs, photovoltaic and fuel cell powered generators utilize solar power and hydrogen-based fuels, respectively, to generate electrical output. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators. Terminology Electromagnetic ...
