Province Of Varese
The province of Varese ( it, provincia di Varese) is a Provinces of Italy, province in the region of Lombardy in northern Italy. Its capital is the city of Varese (population of 80,857 inhabitants), but its largest city is Busto Arsizio. The headquarters of the AgustaWestland, the company merged into Leonardo S.p.A., Leonardo since 2016, the world's largest producer of helicopters, is based in Samarate, a ''comune'' of the province. As of 2015, it has a population of 889,410 inhabitants over an area of . History In Roman times, the fortified settlements of Castelseprio (archaeological park), Castelseprio and the port of Angera were of high importance in the region. The Visconti of Milan, House of Visconti conquered the region in the 13th century and completely destroyed Castelseprio. The House of Visconti used the land for agricultural purposes and as part of the territories of Milan. During this Visconti rule, Varese became prosperous due to high levels of trade in the region bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lombardy
Lombardy ( it, Lombardia, Lombard language, Lombard: ''Lombardia'' or ''Lumbardia' '') is an administrative regions of Italy, region of Italy that covers ; it is located in the northern-central part of the country and has a population of about 10 million people, constituting more than one-sixth of Italy's population. Over a fifth of the Italian gross domestic product (GDP) is produced in the region. The Lombardy region is located between the Alps mountain range and tributaries of the Po river, and includes Milan, the largest metropolitan area in the country, and among the largest in the European Union (EU). Of the fifty-eight UNESCO World Heritage Sites in Italy, eleven are in Lombardy. Virgil, Pliny the Elder, Ambrose, Gerolamo Cardano, Caravaggio, Claudio Monteverdi, Antonio Stradivari, Cesare Beccaria, Alessandro Volta and Alessandro Manzoni; and popes Pope John XXIII, John XXIII and Pope Paul VI, Paul VI originated in the area of modern-day Lombardy region.

Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italy
Italy ( it, Italia ), officially the Italian Republic, ) or the Republic of Italy, is a country in Southern Europe. It is located in the middle of the Mediterranean Sea, and its territory largely coincides with the homonymous geographical region. Italy is also considered part of Western Europe, and shares land borders with France, Switzerland, Austria, Slovenia and the enclaved microstates of Vatican City and San Marino. It has a territorial exclave in Switzerland, Campione. Italy covers an area of , with a population of over 60 million. It is the third-most populous member state of the European Union, the sixth-most populous country in Europe, and the tenth-largest country in the continent by land area. Italy's capital and largest city is Rome. Italy was the native place of many civilizations such as the Italic peoples and the Etruscans, while due to its central geographic location in Southern Europe and the Mediterranean, the country has also historically been home ...

Pumped-storage
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roncovalgrande Hydroelectric Plant
The Roncovalgrande Hydroelectric Plant, also known as the Delio Hydroelectric Plant, is located north of Maccagno in the Province of Varese, Lombardy, Italy. Using the pumped-storage hydroelectric method, the power plant has an installed capacity of . The power plant was complete in 1971 and the last generator operational in 1973. During construction, the upper reservoir, Lago Delio, was expanded in capacity with two gravity dams; a northern and southern, and in height, respectively. The lower reservoir, Lago Maggiore, already existed. The power plant itself is located underground in between Delio and Maggiore. To produce electricity, water is released from the upper reservoir to the power plant via two long penstocks. At the power plant, eight four-stage Pelton turbine-generators generate electricity. Power generation occurs during periods of high energy demand and when energy demand is low, pumping usually occurs. The pumps are on the same shaft as the Pelton turbines and send ...
