Energy Infrastructure Completed In 1962
Energy () is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, the internal energy contained within a thermodynamic system, and rest energy associated with an object's rest mass. These are not mutually exclusive. All living organisms constantly take in and release energy. The Earth's climate and ecosystems processes are driven primaril ...

Dams Completed In 1962
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, drinking water, human consumption, Industrial water, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as Dike (construction), dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam (Jorda ...

Buildings And Structures In Gilan Province
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building pract ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alborz (mountain Range)
The Alborz ( ) range, also spelled as Alburz, Elburz or Elborz, is a mountain range in northern Iran that stretches from the border of Azerbaijan along the western and entire southern coast of the Caspian Sea and finally runs northeast and merges into the smaller Aladagh Mountains and borders in the northeast on the parallel mountain ridge Kopet Dag in the northern parts of Greater Khorasan, Khorasan. All these mountains are part of the much larger Alpide belt. The Alborz range is divided into the Western, Central, and Eastern Alborz Mountains. The Western Alborz Range (usually called the Talysh Mountains, Talysh) runs south-southeastward almost along the western coast of the Caspian Sea. The Central Alborz (the Alborz Mountains in the strictest sense) runs from west to east along the entire southern coast of the Caspian Sea, while the Eastern Alborz Range runs in a northeasterly direction, toward the northern parts of the Khorasan region, southeast of the Caspian Sea.

Hydroelectric Power Stations In Iran
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, 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.

Buttress Dams
A buttress is an architectural structure built against or projecting from a wall which serves to support or reinforce the wall. Buttresses are fairly common on more ancient (typically Gothic) buildings, as a means of providing support to act against the lateral (sideways) forces arising out of inadequately braced roof structures. The term ''counterfort'' can be synonymous with buttress and is often used when referring to dams, retaining walls and other structures holding back earth. Early examples of buttresses are found on the Eanna Temple (ancient Uruk), dating to as early as the 4th millennium BC. Terminology In addition to flying and ordinary buttresses, brick and masonry buttresses that support wall corners can be classified according to their ground plan. A clasping or clamped buttress has an L-shaped ground plan surrounding the corner, an angled buttress has two buttresses meeting at the corner, a setback buttress is similar to an angled buttress but the buttresses ar ...

List Of Power Stations In Iran
By 2012, Iran had roughly 400 power plant units. By the end of 2013, it had a total installed electricity generation capacity of 70,000 MW, which had been increased from 90 MW in 1948, and 7024 MW in 1978. There are plans to add more than 5,000 MW of generation capacity annually to the power grid, which would almost double the total power generation capacity to 122,000 MW by 2022. The government of Iran planned to privatize 20 power plants by September 2010. Iran's peak demand for electricity was 45,693 MW during the summer of 2013. It was predicted that Iran would account for 17.08% of MENA power generation by 2014. Natural gas was the major fuel used to generate electricity in Iran in 2009, accounting for an estimated 56.8% of primary energy demand (PED), followed by oil at 40.8% and hydro power at 1.4%. As of 2010, the average efficiency of power plants in Iran was 38 percent. The figure should reach 45 percent within five years and 50 percent under Vision 2025. Electricity ...

Dams In Iran
Major dam construction started in Iran in the 1950s. Some fourteen large dams were built with the help of foreign engineers and advisors during two decades preceding the Islamic Revolution in 1979. In the post-revolution era, Iran's dam building capacity was significantly strengthened, with some 200 contracting companies, 70 consultant firms and 30 corporations as well as hundreds of hydroelectric manufacturing units having been established inside of Iran in less than three decades. In addition to the necessity of generating electricity, Iran needs dams to effectively control and manage a growing water shortage across the country. Iran was constructing 88 small and large dams in 2007. On average, close to two billion cubic meters of water are added to the country's water reserves annually. As of 2010, Iran has constructed 588 |
