Hojum Power Station
Hojum Power Station (alt. ''Håjum Power Station'') is the second hydroelectric power station in Trollhättan, the first one being the older Olidan Power Station. While the first two turbines were taken into service in 1938, a third one was built and started in 1992. The first two are rated at 50 MW, while the third is rated at 70 MW. The station is mainly located underground in a large mountain hall. This design was chosen because of the political instability in Europe at the time, which later led to the second world war. The relatively small building above ground was drawn by the Swedish Swedish or ' may refer to: Anything from or related to Sweden, a country in Northern Europe.

Hydroelectric Power
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, 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.

Trollhättan
Trollhättan () is the 23rd-largest city in Sweden, the seat of Trollhättan Municipality, Västra Götaland County. It is situated by Göta älv, near the lake Vänern, and has a population of approximately 50,000 in the city proper. It is located 75 km (46 mi) north of Sweden's second-largest city, Gothenburg. History Trollhättan was granted city rights (which today have no legal effect) in 1916 at which time it had about 15,000 inhabitants, now grown to 59,058. Trollhättan was founded on the river Göta älv, at the Trollhättan Falls. The site was first mentioned in literature from 1413. Trollhättan had a strategic significance on the road between Västergötland and Norway. It was also of a commercial and political significance for shipping to and from Vänern. Utilization of the river falls was the first important business activity in the area. From the Middle Ages milling and sawing operations have been conducted where the city center is now located.

Olidan Power Station
Olidan Power Station ( sv, Olidans kraftverk) is a hydroelectric power station located in Trollhättan Municipality, Trollhättan, Sweden. First opened in 1910, it was the first large scale attempt at generating electricity from water in Sweden. The construction of Olidan led to the founding of the ''Kungliga Vattenfallsstyrelsen'' (Royal Waterfall Board), which later became Vattenfall. While the first four turbines were put into service in 1910, construction continued, and another four were put into operation by 1914. Due to increasing demand, as well as increasing capacity due to the regulation of Göta älv, another five were then built. By 1921, Olidan carried a total of 13 turbines. 10 of these are still functioning, while the other three were cannibalized for parts. However, it is currently rare for more than three to be generating at the one time. Each turbine has a capacity of 10 MW. When Olidan were completed in 1924, planning began for Hojum Power Station, which came in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
